Description
The recent detection of gravitational waves by the LIGO/Virgo collaboration has shown we have a new tool to study the physics of binary systems and compact objects, like Black Holes and Neutron Stars. One of the problems we are interested in studying is the existence of new types of particles beyond the Standard Model.
Due to the instability of a process called superradiance, it is theoretically possible that ultralight bosons, which only interact through gravity and are weakly coupled to ordinary matter, condensate in the ergoregion of a black hole and, if they are in the presence of another compact object, such as in binary systems, the gravitational waves emitted by the binary will allow us to probe particles with mass between $10^{-20}$ eV (such as dark matter candidates) and $10^{-10}$ eV (like QCD axions) with future gravitational wave detectors like LISA. In this work, I will focus on the signatures of self-interacting scalar (spin-0) and vector (spin-1) fields due to different physical processes like tidal deformations and accretion effects.
