Description
Future space-based gravitational-wave observatories will open a unique avenue to study the environments surrounding black holes, in particular through the detection of extreme mass-ratio inspirals. In this seminar I will discuss the dynamics and gravitational-wave signatures of extreme mass-ratio inspirals evolving in scalar cloud environments — bosonic condensates that can grow around spinning black holes through superradiance, and which also serve as a useful proxy for modelling more complex environments. I will give an overview of recent efforts to model these systems through fully relativistic perturbative calculations, highlighting some of the interesting phenomena that have emerged from these studies.
