Tidal Deformability of Black Holes Immersed in Matter
Presenting author: Francisco Duque
The tidal deformability of compact objects has a detectable imprint in the gravitational waves emitted by a binary, through quantities known as the Tidal Love Numbers (TLNs). These can be used to constrain the equation of state of neutron stars or to test GR and the nature of black holes. In this talk, we will address the problem of the tidal deformability of black holes immersed in a non-vacuum environment. We will compute the TLNs for specific models of black holes surrounded by matter and apply them to realistic astrophysical scenarios, where the matter describes an accretion disk. We will end by discussing the implications of our results to possible tests of strong-field gravity using TLNs.
