Quasinormal modes of black holes with scalar hair — •Jose Luis Blazquez-Salcedo — Carl von Ossietzky University of Oldenburg, Oldenburg, Germany

We study quasinormal modes of black holes in several alternative theories of gravity. In particular, we focus on theories that include an additional scalar field coupled non-trivially with gravity. Several models exist that allow to obtain black holes with non-trivial scalar hair. In this talk we will discuss some results concerning linear perturbations of these configurations, their ringdown spectrum and their stability.
