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.
The XXVI National Meeting of Astronomy and Astrophysics will take place at the University of Aveiro, on the 8th and 9th September 2016. This meeting is organized by the Department of Physics of the University of Aveiro and the Center for Research and Development in Mathematics and Applications (CIDMA), in partnership with the Portuguese Astronomy Society (SPA).
Abstract: We review different aspects of the construction and perturbations of homogeneous black strings in Gauss-Bonnet and third-order Lovelock theory, which are unstable under s-wave perturbations.
The awakening of the gravitational astronomy era, together with the ever increasing precision of electromagnetic observations, motivates scrutinizing models of alternative compact objects and their phenomenology. As a contribution to this effort, Gr@v researchers will be guest editors of a Focus issue of Classical and Quantum gravity on hairy black holes.
Abstract: The talk is devided into two parts: I will talk about the current status and the prospects of relativistic geodesy and a very interesting project related to this that is called „geoQ“.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
