Abstract: At the end of the 19th century the existence os a planet beyond Neptune was in debate. In 1930, Pluto was discovered, but too far from the prediction. In 1992 we found out that Pluto is actually a member of a huge belt of icy bodies orbiting beyond Neptune.
Abstract: Active galactic nuclei (AGNs) are extreme astrophysical environment that result in copious emission of X-rays. I describe how large archival datasets from X-ray telescopes can be used to search for new physics using the X-ray spectrum of AGNs.
For the second time C. Herdeiro was the guest interviewee of Porto Canal's "Mentes que Brilham". Watch and listen to the conversation (from minute 18 onwards) (Watch and listen to the first interview) with interviewer Cláudia Fonseca about black holes and some of the research work made at Gr@v in this area.
Gr@v member António P. Morais gave a talk at Escola Secundária José Régio in Vila do Conde with title "Do Infinitamente Grande ao Infinitamente Pequeno - uma jornada pelas interações fundamentais na natureza". António was an invited speaker to participate in a sequence of seminars entitled "A Biblioteca convida...", and presented to 11th and 12th grade Science and Technology students the four fundamental interactions in nature and how have they shaped our Universe.
Gr@v member Carlos Herdeiro was one of the invited speakers of the 5th UTQuest workshop, with the theme "Hidden Sector Physics and Cosmophysics", that took place at the Yukawa Insitute for Theoretical Physics, Kyoto University, Kyoto, Japan.
Gr@v's Ph.D. student (in collaboration with IST-Lisbon) Pedro Cunha produced a short movie illustrating a voyage into a black hole, and in particular the lensing effects visualized by an observer undergoing such journey. The journalist Catarina Lázaro (voice) and Gr@v researcher C. Herdeiro (scientific advising) collaborated in the movie, which will have a premiere on December 3rd 2016 at "Observatório Geofísico e Astronómico da Universidade de Coimbra".
The European Space Agency (ESA) Advanced Concepts Team (ACT) has created a cool interactive webpage for visualization of the lensing due to a black hole, featuring black holes with scalar hair found by our group. Try it here! (Works better with the Chrome browser)
The proceedings of the third Amazonian Symposium on Physics, held in Belém, Brazil (28th Sep - 2nd Oct 2015), have been published as a special issue of IJMPD. This meeting closed the successful NRHEP Marie Curie action (2012-2015), coordinated by our group, and the proceedings are edited by the action's node coordinators.
The 20th National Meeting of the Portuguese Physics Society (SPF) took place at the University of Minho, in Braga, in the 8-9 September 2016. Gr@v member C. Herdeiro was one of the invited plenary speakers.
