          El ministro de Ciencia muestra su apoyo a la instalación del megatelescopio TMT en La Palma      Cache   Translate Page   Web Page Cache   

El ministro de Ciencia, Innovación y Universidades  del Gobierno de España, Pedro Duque, desde Tenerife, ha mantenido una reunión por videoconferencia con la dirección del proyecto del Telescopio de Treinta Metros (TMT, en sus siglas en inglés). Durante este contacto ha mostrado el apoyo de su Ministerio y de las demás Administraciones a la instalación del TMT en La Palma, informa el Instituto de Astrofísica de Canarias (IAC). "Todos trabajaremos unidos para conseguir el éxito del proyecto si se decide instalarlo en La Palma", afirmó Pedro Duque. El Roque de Los Muchachos es la segunda opción para albergar el TMT. La primera es el observatorio de Mauna Kea,  en Hawái. La decisión final, dependiente de un proceso ante los tribunales de la citada isla de EEUU, se conocerá en fechas próximas. 

Plan estratégico de los observatorios de Canarias

El IAC, en comunicado, informa que ministro de Ciencia, Universidades e Innovación y el presidente del Gobierno de Canarias han asistido a la reunión anual del Consejo Rector del Instituto de Astrofísica de Canarias (IAC), que se ha celebrado este martes en su sede central, en La Laguna. Entre otros temas, se han presentado el plan estratégico para los Observatorios de Canarias y un estudio sobre el impacto socioeconómico del sector astrofísico en las Islas.

“La producción científica del IAC puede continuar a la vanguardia del mundo en la Astrofísica”, aseguró en rueda de prensa el ministro de Ciencia, Universidades e Innovación, Pedro Duque, quien estuvo acompañado del presidente del Gobierno de Canarias, Fernando Clavijo, y del director del IAC, Rafael Rebolo, al término de la reunión del Consejo Rector del IAC. En ella se ha informado de la actividad del centro en 2017 así como del plan estratégico para los Observatorios de Canarias, con los proyectos de los futuros grandes telescopios, lo que supondrá importantes inversiones en las Islas durante los próximos años. “En esta reunión”, añadió el ministro, “nos han presentado también un informe adicional que ha elaborado la Universidad de La Laguna sobre el impacto económico que la Astrofísica y que este Instituto tiene sobre la sociedad de Canarias”. El informe afirma que cada euro invertido en Astrofísica por las Administraciones se generan, al menos, 4 euros en el PIB de las Islas.

Fernando Clavijo destacó en la reunión que el Gobierno de Canarias ha aportado a la financiación del IAC y a la creación de los diferentes observatorios e instrumentación de los mismos, incluyendo el Gran Telescopio Canarias, más de 45 millones de euros, desde 2014 hasta 2021. “El IAC sitúa a Canarias como uno de los principales centros de investigación en el campo de la Astrofísica. La excelente calidad astronómica de nuestros cielos hace de los Observatorios del IAC una reserva astronómica global abierta a la comunidad científica internacional desde 1979, que puede considerarse como una concreción del concepto transversal de Laboratorio Natural en la RIS3 de Canarias".

Además, el presidente canario expresó que "este hecho ha colocado a Canarias en el punto de mira para el establecimiento de las grandes infraestructuras científicas más avanzadas en el campo de la Astrofísica, como el Telescopio Solar Europeo (EST), el Telescopio Robótico Liverpool 2 (LT2) y la red de telescopios para altas energías Cherenkov Telescope Array (CTA), entre otros. A estos proyectos se le podría sumar próximamente el Thirty Meter Telescope (TMT), lo que supondría una oportunidad única para la mejora de las capacidades tecnológicas vinculadas a la investigación astrofísica, un impulso para el desarrollo diversificado de la economía canaria con la creación de empresas de base tecnológica y la atracción de grandes empresas del sector, así como de talentos y personal cualificado hacia el Archipiélago, factores que incidirán positivamente en el desarrollo socio económico de nuestra región".

Presupuesto y personal

En cuanto a los temas presupuestarios, sujeto a disponibilidad presupuestaria, se apunta en la nota, se ha aprobado un incremento del 8% en el presupuesto del IAC para el año 2019. En lo relativo al personal del centro, Pedro Duque señaló: “Hemos hablado sobre todo de la estabilización del personal, de la reestructuración de los diversos puestos de trabajo, de manera que se plantee un Instituto con perspectivas de futuro y con la suficiente flexibilidad. La estabilización del personal suele ser una de las primeras reivindicaciones o carencias que hay que suplir y, por supuesto, vamos a seguir apoyando internacionalmente a los diversos países que quieran ubicar instalaciones tanto en La Palma como en Tenerife. Tendremos en cuenta todos los contactos internacionales”.

También se anunció en rueda de prensa la renovación del cargo de director del IAC. “Unánimemente hemos aprobado que Rafael Rebolo sea el director del Instituto por un nuevo periodo de 5 años. Le estamos muy agradecidos por continuar esta labor”, ha declarado Duque.

Encuentro con investigadores

Antes de comenzar la reunión del Consejo Rector, el Ministro realizó un recorrido por las instalaciones del IAC y tuvo un encuentro informal con el personal investigador del centro en el que pudo intercambiar impresiones sobre el sistema científico español. En concreto, sobre la financiación a largo plazo para los proyectos de instrumentación, la estabilización laboral de los posdocs retornados a España con el programa Ramón y Cajal y la retirada de las trabas burocráticas, especialmente en compras y contrataciones. Pedro Duque valoró su visita diciendo: “La impresión que me llevo es de un personal muy motivado y con grandes capacidades. Estoy viendo también todas esas posibilidades de desarrollo tecnológico que se están realizando en este Instituto, muy interesantes desde el punto de vista del desarrollo científico del país. Hay que ponerlas en valor. Vamos a ver cómo conseguimos que este desarrollo tecnológico tenga su utilización en el futuro”.

Objetivos y prioridades

El plan estratégico de los Observatorios de Canarias, se indica en la nota, describe la dirección estratégica, los objetivos y las prioridades que el IAC perseguirá para hacer realidad su visión de futuro. Se han identificado tres objetivos estratégicos –liderazgo, internacionalidad e innovación- que fortalecerán la capacidad de los Observatorios de Canarias para cumplir su misión y contribuir a mantener España a la vanguardia de la investigación en Astrofísica y el desarrollo tecnológico relacionado. Para lograrlo, se requiere la puesta en marcha de un plan que perseguirá las siguientes seis estrategias específicas durante el período 2017-2021: facilitar la investigación astrofísica de primer nivel mundial; mejorar el apoyo científico y las capacidades tecnológicas en los Observatorios, incluyendo el desarrollo conjunto de la instrumentación; continuar mejorando la calidad y cantidad de los servicios y las infraestructuras de apoyo en el Observatorios; proteger la calidad del cielo y el medio ambiente; y fortalecer las habilidades de ciencia, tecnología e ingeniería así como mejorar su percepción social.

“Este plan estratégico –explicó Rafael Rebolo- persigue mejorar las infraestructuras básicas que tienen los Observatorios y favorecer la llegada de nuevas instalaciones de frontera científica. Contempla la participación del Instituto en desarrollos técnicos para esos grandes telescopios, mejoras de todo tipo, los accesos, los suministros eléctricos, haciendo los Observatorios más sostenibles medioambientalmente… En fin, todo lo que lleva consigo una gran infraestructura científica como son los Observatorios de Canarias y que requiere un plan y una previsión. Esta propuesta es lo que les hemos presentado en esta reunión, aunque está sujeta a evaluaciones estrictas que se llevan a cabo en comisiones internacionales y de cuyo resultado nos informará el Ministerio”.

A la reunión anual del Consejo Rector del IAC, que preside el  Ministro de Ciencia, Universidades e Innovación, Pedro Duque, asistieron el presidente del Gobierno de Canarias, Fernando Clavijo; la directora general de Política de Investigación, Desarrollo e Innovación, Clara Eugenia García; la delegada del Gobierno en Canarias, Elena Máñe; el consejero de Economía, Industria, Comercio y Conocimiento del Gobierno de Canarias, Pedro Ortega; el rector de la Universidad de La Laguna (ULL), Antonio Martinón; el presidente en funciones del Cabildo de Tenerife, Aurelio Abreu, y el presidente del Cabildo Insular de La Palma, Anselmo Pestana.

Los Observatorios del Instituto de Astrofísica de Canarias (IAC) y el  Gran Telescopio Canarias (GTC) forman parte de la red de Infraestructuras Científicas y Técnicas Singulares (ICTS) de España.

          HEAVILY REDUCED Revolution Imager R2 Set with lots of Accessories.      Cache   Translate Page   Web Page Cache   
For Sale

PRICED TO SELL! ALMOST $500 OF GEAR GOING FOR $300. PRICE IS FIRM
I am selling the standard Revolution Imager R2 kit with a bunch of added accessories. I used this maybe 4 times. This camera is a very good camera to try EAA with, especially if you do not want to lug a laptop into the field. The Revolution Imager does NOT have a case with it. I lost it in an accident I had with my house. The accessories I have are the following:

DVR for capturing video. This does not need a computer to work and comes with a 16gb micro sd card and adapter. You can then take home the videos you captured and throw them into a program like registax and process them if you wish. This would be great for capturing videos of the planets this summer!

All-Sky Camera for 150-degree views. All of the milky way videos shown are taken with this.

25-foot standoff cable. This allows you to stay inside and view if your telescope has tracking capabilities. I used this MANY times when it was sub-zero celcius outside and I wanted to still do EAA.

The Ball-head mount for the LCD monitor or the camera on a tripod

USB Video capture card. Allows you to capture video and do live stacking with a program like sharpcap. If you pursue AP, you can also use this to access sharpcap's polar alignment tool.

Paypal only. The buyer pays for shipping costs and the PP fee. Calculated shipping to the CONUS via flat rate is around 15 dollars.

Pictures of individual items can be taken if requested.

          Ο Αϊνστάιν επιβεβαιώνεται και στις πιο ακραίες συνθήκες      Cache   Translate Page   Web Page Cache   
Σπύρος Μανουσέλης


Από τα μαθητικά μας χρόνια μαθαίνουμε ότι η βαρύτητα είναι παγκόσμια και ότι όλα τα σώματα, ανεξάρτητα από τη μάζα τους, πέφτουν με την ίδια ταχύτητα. Αυτό επιτάσσει η περίφημη «Αρχή της Ισοδυναμίας»: μια θεμελιώδης αρχή της κλασικής Φυσικής που τη διαφώτισαν με το έργο τους ο Γαλιλαίος, ο Νεύτωνας και ο Αϊνστάιν.

Σύμφωνα με ένα πολύ διαδεδομένο μύθευμα, ο Γαλιλαίος ανακάλυψε πρώτος την ισοδύναμη δράση της βαρύτητας σε όλα τα σώματα ρίχνοντας αντικείμενα διαφορετικών μεγεθών από τον Πύργο της Πίζας.

Στην πραγματικότητα, όμως, ο Γαλιλαίος απέδειξε ότι «σώματα με διαφορετική μάζα επιταχύνονται εξίσου εντός ενός κοινού βαρυτικού πεδίου» μελετώντας τις ταλαντώσεις ενός εκκρεμούς και διαφορετικές σφαίρες ενώ κυλούσαν σε κεκλιμένο επίπεδο. Μια άλλη διατύπωση αυτής της Αρχής Ισοδυναμίας μάς έδωσε ο Νεύτωνας, σύμφωνα με τον οποίο «η αδρανειακή και η βαρυτική μάζα κάθε σώματος είναι ίσες μεταξύ τους».

Πριν από σχεδόν έναν αιώνα, ο Αϊνστάιν με τη γενική θεωρία της σχετικότητας εισάγει μια παρόμοια Αρχή Ισοδυναμίας, την οποία συσχέτισε με την καμπυλότητα του χωροχρόνου.

Μια βασική παραδοχή της γενικής θεωρίας σχετικότητας που, μέχρι σήμερα, δεν είχε επαληθευτεί από αστρονομικές παρατηρήσεις (ούτε όμως και διαψευστεί).

Για να την εξετάσει λοιπόν εμπειρικά μια ομάδα ερευνητών στην Ολλανδία αποφάσισε να μελετήσει τηλεσκοπικά μια περιοχή του Διαστήματος όπου το βαρυτικό πεδίο φτάνει σε ακραία υψηλές τιμές, όπως συμβαίνει με το βαρυτικό πεδίο που δημιουργεί ένας αστέρας νετρονίων.

Η πρόσφατη έρευνα βασίστηκε στο καλά επιβεβαιωμένο γεγονός ότι αν η μάζα ενός αστεριού είναι αρκετά μεγάλη, αν είναι 8 έως 18 φορές μεγαλύτερη από τη μάζα του Ηλίου μας, τότε όταν αυτό το αστέρι «πεθαίνει», όταν δηλαδή καταρρέει βαρυτικά, καταλήγει σε έναν υπέρπυκνο αστέρα νετρονίων, ενώ αν η αρχική μάζα του ήταν πολύ μεγαλύτερη θα κατέρρεε δημιουργώντας τελικά μια μαύρη τρύπα.

Όταν, αντίθετα, το αστέρι έχει πιο μικρή ή μεσαία μάζα, τότε καταρρέει σε λευκό νάνο.

Σύμφωνα με τα δεδομένα μιας πρόσφατης έρευνας, που δημοσιεύτηκε μόλις πριν από τρεις μέρες στο γνωστό περιοδικό «Nature», η Αρχή Ισοδυναμίας που προβλέπεται από τη γενική σχετικότητα ισχύει ακόμη και σε πολύ ακραίες συνθήκες.

Την έρευνα υπογράφει η Anne Archibald, αστροφυσικός στο Πανεπιστήμιο του Αμστερνταμ, η οποία μαζί με μια διεθνή ομάδα ερευνητών μελέτησε, μέσω του ισχυρού ραδιοτηλεσκοπίου GBT (Green Bank Telescope), ένα «τριπλό ηλιακό σύστημα» το οποίο απέχει από τη Γη 4.200 έτη φωτός.

Πρόκειται για το ηλιακό σύστημα «PSR J0337+1715» (βλέπε φωτ.), ένα σπάνιο φυσικό εργαστήριο ιδανικό για τέτοιες παρατηρήσεις, διότι αποτελείται ταυτοχρόνως από έναν αστέρα νετρονίων που περιστρέφεται γύρω από έναν λευκό νάνο κάθε 1,6 ημέρα, ενώ αυτό το διπλό σύστημα αστέρων είναι από κοινού σε τροχιά και εκτελεί μία περιφορά κάθε 327 ημέρες γύρω από έναν άλλον, πολύ πιο απομακρυσμένο λευκό νάνο.

Αναλύοντας τη δυναμική αυτού του σπάνιου συστήματος που αποτελείται από έναν αστέρα νετρονίων και δύο λευκούς νάνους, οι ερευνητές διαπίστωσαν ότι οι προβλέψεις ισοδυναμίας της γενικής σχετικότητας επιβεβαιώνονται: δεν υπάρχει καμιά ορατή διαφορά ανάμεσα στον τρόπο που επιταχύνονται αυτά τα τόσο διαφορετικής μάζας αντικείμενα, όπως το δίπολο αστέρας νετρονίων και λευκός νάνος σε σχέση με τον απομακρυσμένο λευκό νάνο. Με άλλα λόγια, η θεωρία της σχετικότητας επιβεβαιώνεται για μία ακόμη φορά και μάλιστα σε πολύ ακραίες συνθήκες.

Así se investiga en un laboratorio bajo tierra en los Pirineos#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000\

El físico teórico Carlos Peña Garay ha sido nombrado nuevo director del laboratorio de Canfranc. Hipertextual le ha entrevistado para conocer cuál es el presente y futuro de los experimentos que allí se realizan.

El Laboratorio Subterráneo de Canfranc (LSC) es peculiar: se encuentra a 800 metros bajo tierra para evitar que los rayos cósmicos interaccionen con los experimentos que se realizan en el Pirineo Aragonés, bajo la Montaña del Tobazo. Estas investigaciones se pueden agrupar en tres tipos: búsqueda de desintegraciones beta y doble beta; búsqueda de materia oscura y pruebas para el Einstein Telescope y otros interferómetros.

Ahora, este laboratorio subterráneo tiene como nuevo director al físico teórico e investigador del CSIC Carlos Peña Garay, que en los inicios de su carrera participó en el descubrimiento de la masa de los neutrinos.

Más allá del nombramiento de Peña Garay como director, ¿qué es exactamente lo que se cuece entre los científicos a 800 metro bajo tierra?

Desintegraciones beta y doble beta

Uno de los principales experimentos que se desarrolla en Canfranc está relacionado con las desintegraciones "raras", según explica Peña Garay a Hipertextual. "En concreto hay una desintegración, llamada desintegración beta porque es la segunda que se descubrió, que se da cuando un núcleo no es estable y cambia un protón por un neutrón o viceversa. Esta desintegración produce la emisión de un electrón o de un positrón (pareja del electrón con carga contraria, es antimateria). El núcleo (la distribución de protones y neutrones) cambia aunque no lo hacen los nucleones", ilustra el investigador del CSIC.

No obstante, siempre hay núcleos más difíciles de desintegrar: "Cuando un núcleo puede desintegrarse beta, pero no tiene la energía suficiente para hacerlo, se desintegra doble beta: cambia dos protones por dos neutrones o viceversa", comenta el físico. Además, en este proceso se crean "uno o dos neutrinos", añade. "Esto ya se ha medido en algunos núcleos". "Hay algunos núcleos muy especiales que no pueden tener desintegración beta, pero sí doble beta, lo cual es muy raro. La vida de algunos de estos núcleos es de 10 elevado a 21 años. Son núcleos casi estables, es decir, muy poco inestables y eso se puede medir. Para verlo tienes que ir a un laboratorio subterráneo donde suprimes la mayoría del ruido radiactivo que hay alrededor, es decir, los rayos cósmicos, y así poder ver este efecto", explica Peña Garay.

Y esto es lo que están haciendo en el LSC con el experimento NEXT, en el que se utiliza el isótopo Xenón-136, "que no se puede desintegrar beta, pero sí doble beta". Los isótopos son átomos del mismo elemento que varían en el número de neutrones en su núcleo. "Es una desintegración muy especial donde se emiten los dos electrones, pero los neutrinos no salen del núcleo, no se han producido. Esto es teórico, los físicos teóricos hemos convencido a los físicos experimentales que debería de ocurrir", explica el investigador del CSIC.

Entonces, ¿qué implicaría descubrir que esto es así? "Dos cosas. La primera, los neutrinos tienen que ser su propia antipartícula" y es posible ya que no tienen carga ni positiva ni negativa "y necesitaríamos nueva física para explicarlo". "La segunda, más especulativa, trata sobre los neutrinos de Majorana, llamados así por un físico italiano que planteó la posibilidad de que si son su propia antipartícula, en el universo temprano, cuando había tanto partículas como antipartículas, hubo una batalla de aniquilación entre ellas y daban luz. Y todo se convirtió en luz excepto un pequeño exceso de materia frente a antimateria. Este exceso se debió a que el neutrino es de Majorana y generó esa pequeña diferencia de una parte sobre otra. La diferencia es muy pequeña, de una parte entre cuatro mil millones, pero el neutrino la podría generar. Por eso es tan importante buscar esta desintegración", explica a Hipertextual.

Detectores de materia oscura

Al observar una galaxia y seguir su trayectoria se puede determinar cuánta materia hay dentro por la gravedad. Sin embargo, los científicos se han dado cuenta de que al realizar los cálculos de la gravedad los números no les salen: "Sabemos que hay cinco veces más masa de la que vemos en una órbita", señala Peña Garay. A la sustancia desconocida, por el momento, que no vemos, pero que los investigadores saben que está ahí por los efectos de la gravedad se la ha llamado materia oscura. "Todavía no sabemos lo que es y, aunque creemos que interactúa como un partícula, no la hemos podido ver", explica el físico teórico.

El experimento para encontrar a la escurridiza materia oscura es sencillo, aunque eso no quita que sea muy difícil dar con ella: se instalan unos "detectores muy sensibles con los que se ve pasar incluso algo con lo que interactúa muy débilmente", de ahí que se necesiten laboratorios subterráneos para llevar a cabo este experimento, con los que se debería detectar cualquier pequeña variación de la energía al entrar en contacto con otra partícula que la atraviese, como una de materia oscura. "Tenemos varios detectores funcionando y es una de las áreas más importantes en laboratorios subterráneos", comenta el investigador.

Einstein Telescope

"Uno de nuestros proyectos está relacionado con las ondas gravitacionales, que han aparecen tras el colapso de objetos masivos y nos llegan hasta nosotros. Con experimentos de mucha precisión que miden distancias perpendicular una de otra con láseres que conectan espejos a 8 kilómetros de distancia somos capaces de saber que está pasando una onda gravitacional que modifica las distancias en una dirección y en otra. Sabemos que el futuro de estos detectores es que se pondrán bajo tierra porque eso reducirá un tipo de ruido a bajas frecuencias y me permitirá ver más objetos que su evolución genera ondas gravitacionales", explica el físico teórico.

El Einstein Telescope es uno de los proyectos, de origen europeo, que pretende estudiar esto. Se construiría un interferómetro gigante, un instrumento que permite medir largas distancias de una forma muy precisa. Será un triángulo equilátero de ocho kilómetros de lado cuyos vértices se estarán midiendo de forma continua. Aún no se sabe dónde se pondrá, pero se están buscando localizaciones y en Canfranc se estudia "si la roca de aquí es buena para este tipo de instrumentos".

No obstante, hay un segundo proyecto relacionado con interferómetros más pequeños "con los que podemos ver grandes mareas en el golfo de Vizcaya o terremotos en el otro lado del mundo", detalla el investigador.

Bajo tierra también se aprende biología

Un área en el que Peña Garay tiene interés en invertir en un futuro próximo es en el campo de la biología y la física. "Hay un tipo de experimento en superficie que consiste en coger un sistema celular, que puede ser desde células individuales hasta tejidos, e irradiar radiación gamma. Las células se dañan, pero algunas sobreviven porque el ADN tiene un sistema de reparación. Esto se sabe, es parte del campo de la biología", comenta el físico teórico. Pero el equipo de Luigi Satta ha replicado los experimentos en el laboratorio subterráneo de Gran Sasso y ha encontrado "un fenómeno que inicialmente sorprende".

¿Y qué han encontrado? "Que, aunque fueran las mismas condiciones, las células no sobrevivían. Todavía no entendemos todo lo que pasa, pero una hipótesis es que la vida está adaptada a vivir en superficie y, por lo tanto, la radiactividad que está afectándonos a nosotros ahora mismo hace que nuestro sistema esté activado, de modo que está preparado para reparar porque constantemente está siendo agredido. En un laboratorio subterráneo el número de ataques por radioactividad disminuye y, por lo tanto, el sistema de reparación se deprime y no tiene capacidad de reaccionar cuando haces este daño. Es una hipótesis, puede que no sea correcta. Pero es uno de los efectos que queremos estudiar caracterizando qué le ocurre a la vida cuando disminuye el nivel de radiactividad, la radiación electromagnética, los efectos acústicos...", explica el investigador.

Plan estratégico más allá del Gobierno

El nuevo Gobierno formado por Pedro Sánchez ha dado, de nuevo, relevancia a la Ciencia al incluir un ministerio que está dirigido por el astronauta y científico Pedro Duque. Para Peña Garay esto "podría ser un buen signo, tenemos que ver cómo evoluciona". No obstante, cree que para que la ciencia "funcione" en España es necesario un "programa bien definido y a largo plazo, independientemente del Gobierno". Este debería incluir un "plan estratégico" con un esquema "para incorporar nuevos científicos al sistema que sea estable". A nivel económico, además, debería evitarse al máximo que la ciencia se vea "perturbada" por la situación nacional o autonómico. "Sé que es difícil de conseguir... Pero inicialmente los signos del nuevo Gobierno parecen buenos, iremos viendo", concluye.


          Detection of Bursts from FRB 121102 with the Effelsberg 100-m Radio Telescope at 5 GHz and the Role of Scintillation      Cache   Translate Page   Web Page Cache   
arXiv:1807.03722

by: Spitler, Laura G.
Abstract:
FRB 121102, the only repeating fast radio burst (FRB) known to date, was discovered at 1.4 GHz and shortly after the discovery of its repeating nature, detected up to 2.4 GHz. Here we present three bursts detected with the 100-m Effelsberg radio telescope at 4.85 GHz. All three bursts exhibited frequency structure on broad and narrow frequency scales. Using an autocorrelation function analysis, we measured a characteristic bandwidth of the small-scale structure of 6.4$\pm$1.6 MHz, which is consistent with the diffractive scintillation bandwidth for this line of sight through the Galactic interstellar medium (ISM) predicted by the NE2001 model. These were the only detections in a campaign totaling 22 hours in 10 observing epochs spanning five months. The observed burst detection rate within this observation was inconsistent with a Poisson process with a constant average occurrence rate; three bursts arrived in the final 0.3 hr of a 2 hr observation on 2016 August 20. We therefore observed a change in the rate of detectable bursts during this observation, and we argue that boosting by diffractive interstellar scintillations may have played a role in the detectability. Understanding whether changes in the detection rate of bursts from FRB 121102 observed at other radio frequencies and epochs are also a product of propagation effects, such as scintillation boosting by the Galactic ISM or plasma lensing in the host galaxy, or an intrinsic property of the burst emission will require further observations.
          Unveiling the enigma of ATLAS17aeu      Cache   Translate Page   Web Page Cache   
arXiv:1807.03681

by: Melandri, A.
Abstract:
Aim. The unusual transient ATLAS17aeu was serendipitously detected within the sky localisation of the gravitational wave trigger GW170104. The importance of a possible association with gravitational waves coming from a binary black hole merger led to an extensive follow-up campaign, with the aim of assessing a possible connection with GW170104. Methods. With several telescopes, we carried out both photometric and spectroscopic observations of ATLAS17aeu, for several epochs, between $\sim 3$ and $\sim 230$ days after the first detection. Results. We studied in detail the temporal and spectroscopic properties of ATLAS17aeu and its host galaxy. We detected spectral features similar to those of a broad lined supernova superposed to an otherwise typical long-GRB afterglow. Based on analysis of the optical light curve, spectrum and host galaxy SED, we conclude that the redshift of the source is probably $z \simeq 0.5 \pm 0.2$. Conclusions. While the redshift range we have determined is marginally compatible with that of the gravitational wave event, the presence of a supernova component and the consistency of this transient with the E$_{\rm p}$-E$_{\rm iso}$ correlation support the conclusion that ATLAS17aeu was associated with the long gamma-ray burst GRB170105A. This rules out the association of the GRB170105A/ATLAS17aeu transient with the gravitational wave event GW170104, which was due to a binary black hole merger.

A 5,5 mil anos-luz da Terra, na constelação de Vela, há um aglomerado de estrelas fascinante. Trata-se do RCW 38, que une várias estrelas grandes, quentes e jovens. 

O telescópio VLT (Very Large Telescope, em inglês) do Observatório Europeu do Sul (ESO) registrou uma bela imagem do RCW 38. Localizado no Chile, o aparelho foi utilizado em conjunto com uma câmera infravermelha conhecida como HAWK-I e o sistema ótico GRAAL para realizar o clique. 

Foram necessários vários testes entre o HAWK-I e o GRAAL antes do registro oficial: a câmera opera a partir de ondas infravermelhas, enquanto o sistema o ajuda a alinhar sua visão e captar as imagens.

A região azul da foto corresponde ao centro do aglomerado, onde ficam as estrelas mais jovens e as que ainda estão em formação. Segundo o observatório, a radiação intensa emitida pelas novatas deixa o gás em volta delas brilhante. A poeira cósmica mais fria aparece em tons de vermelho e laranja. O contraste entre as duas cria essa imagem espetacular.

Thousands of exoplanets are known to orbit distant stars. Far fewer have had their atmospheres studied. The Webb telescope will bring new capabilities for determining atmospheric compositions, temperatures, and structures. Some of Webb’s earliest observations will focus on gas giants, whose puffy atmospheres should be easier to inspect. Lessons learned there will apply to later observations of small, rocky worlds.

Pirámide de Vandama.

The island of La Palma is a beautiful place filled with inky volcanic beaches, telescopes, and nature reserves. What some visitors don't know is that it's also littered with ancient pre-Hispanic ruins left by the island's indigenous inhabitants, the Guanches. 

Indigenous to the Canary Islands, the Guanches had the bad luck of being discovered by the Spanish, who conquered and absorbed their society. The Spanish did a predictably thorough job, but Guanche ruins can still be found scattered around the islands. 

One of the most impressive ruins is the Pirámide de Vandama, a step pyramid made of smartly stacked stones. Visible from the tourist district of Los Cancajos, it has been subject to many legends and stories. Some skeptics say it's a new structure made for the tourists, while others insist it's an ancient sacrificial ground where captured Spaniards were murdered. Old accounts from a visiting Spanish captain suggest it was used as a place to dry fruits. 

Modern archeologists have determined that the pyramid is indeed pre-Hispanic and information about it can be found in the local museum dedicated to the island's history. The pyramid itself is, however, fully accessible if you know where to go, and unfortunately not currently protected. So if you visit, please do your part to leave the historic pyramid untouched.

          Nearby exoplanet Ross 128 b is looking more and more like Earth’s bigger cousin      Cache   Translate Page   Web Page Cache   
Exoplanet discoveries have been coming fast and furious for several years now, thanks in large part to increasingly power telescope technology that allows us to study the heavens in greater detail than ever. Many of the exoplanets that astronomers spot are very clearly inhospitable to life due to their distance from their star, or the chemical signatures we are able to detect from afar, but Ross 128 b, located just 11 light years away, is much different. Ross 128 b is a planet orbiting the star Ross 128 (see how that works?), and it's within what is known as the "goldilocks" zone, which is the distance from its host star that would make its surface neither too not nor too cold to support life. Scientists have known about Ross 128 b's location for some time already, but new research is giving even more weight to the theory that the planet could indeed be an Earth-alike. Because Ross 128 b is such a rare case — orbiting a bizarrely inactive red dwarf star that is calm enough to potentially allow life to take root on its nearby planet — scientists wanted to figure out what the planet is actually made of. In order to do that, they took a closer look at the star that it orbits. The work was published in Astrophysical Journal Letters. In a planetary system, the star and the planets that surround it are largely made of the same kind of material. The chemical composition of the star is a good indicator for how much of various elements is present within the planets that surround it, and scientists can study the light that the star produces to get a rough idea of what's inside. Ross 128 is looking very, very promising. The star is smaller than our Sun, but it has comparable levels of iron. Combining that with a measurement of the star's magnesium levels, the team was able to determine that its nearby planet is almost certainly rocky, like Earth, and it might even be larger than our own planet. Using size estimates, the planet's levels of heat and light exposure were also calculated, and the planet falls well within the limits to support life as we know it on Earth. "It's exciting what we can learn about another planet by determining what the light from its host star tells us about the system's chemistry," lead researcher Diogo Souto explains. "Although Ross 128 b is not Earth's twin, and there is still much we don't know about its potential geologic activity, we were able to strengthen the argument that it's a temperate planet that could potentially have liquid water on its surface."
          New telescope camera snaps gorgeous image of distant star cluster      Cache   Translate Page   Web Page Cache   
NASA regularly delivers outer space eye candy snapped with its various telescopes, but the European Southern Observatory has plenty of star-gazing power as well, and it just released a new piece of "celestial art" that will stand toe-to-toe with any space photo you've ever seen. Captured with the newly installed HAWK-I infrared imager on the Very Large Telescope in Chile, the photo of star cluster RCW 38 is truly a thing of beauty. What makes the photo so fantastic is the ability of the camera to capture the image in infrared rather than optical wavelengths of light. When relying on optical imaging, any debris between the camera and the light source acts like a mask, but infrared can cut through much of that and reveal the stars and hiding in the background. There's a whole lot going on in this image, and you're forgiven if you can't make sense of all the colors, but ESO has provided a quick rundown of what we're seeing:
The central area of RCW 38 is visible here as a bright, blue-tinted region, an area inhabited by numerous very young stars and protostars that are still in the process of forming. The intense radiation pouring out from these newly born stars causes the surrounding gas to glow brightly. This is in stark contrast to the streams of cooler cosmic dust winding through the region, which glow gently in dark shades of red and orange. The contrast creates this spectacular scene — a piece of celestial artwork.
What's perhaps most amazing about this incredible image is that it's actually just a test run of some of the telescope's new tools. The photos were snapped as part of the science verification process that gives scientists a sense of what the hardware is capable of. If this is just a taste of what's to come, I think we can all be very excited for the future.
