Abstract: Anti-de Sitter is not a globally hyperbolic spacetime. When studying a field theory on anti-de Sitter, one needs an appropriate choice of boundary conditions at the conformal boundary such that the classical field equation is well-posed.
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)
Jorge Delgado successfully finished his Physics M.Sc. at Aveiro University, on September 20th 2016, by defending a thesis with title "Kerr black holes with electric charge and scalar hair". This thesis was supervised by Gr@v researchers and examined by Prof. Filipe Mena, from the University of Minho. Well done Jorge!
Abstract: On 14 September 2016, the Laser Interferometer Gravitational-WaveObservatory (LIGO) detected the first gravitational wave signal everdirectly observed. This observation also represents the first directobservation of a black-hole binary and has opened up a qualitatively newwindow to the universe.
In the wake of the detection of gravitational waves from black hole mergers and at the door step of an era of precision electromagnetic observations of the horizon scale for black hole candidates, in particular with the Event Horizon Telescope, the gravitation groups at Aveiro University, Gr@v, and at IST-Lisbon, Grit, will organize a two days workshop on Gravitational Lensing and Black Hole Shadows, held at the University of Aveiro (Portugal), on the 3rd and 4th of November 2016.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
