Gulbenkian Awards 2015 Ceremony
The ceremony for distinguising the recipients of the 2015 Gulbenkian Prizes for Stimulus of Research, took place on March 9th 2016, at the Gulbenkian Foundation, in Lisbon. Pedro Cunha was awarded one of the prizes for his project on "Black Hole Shadows".

Abstract: I will present our results of a series of numerical relativity simulations of dynamical nonrotating black holes surrounded by self-gravitating scalar fields. In the non-charged case, even in the non-linear regime, quasistationary configurations of scalar fields are formed around black holes.

Abstract: The ESO/GRAVITY is an adaptive optics and fringe tracker assisted K-band interferometric spectrograph. The instrument development started in the last decade and reached first fringes with the auxiliary telescopes in December 2015.
Resolving black hole singularities

Abstract: We discuss how space-time singularities inside black holes can be resolved using the Palatini approach for modified gravity. In this approach metric and affine connection are taken as independent variables.
Hairy black holes can form dynamically
In 2014, it was found that black hole (BH) solutions in General Relativity exist in stationary equilibrium with (good) matter: hairy BHs. An investigation published in Physical Review Letters shows, in a toy model, that analogous hairy BHs can form dynamically.
