Description

Superradiance offers a unique link between particle and black hole physics. Through this process, a cloud of light particles can build up around a spinning black hole that resembles the hydrogen atom. If the black hole is part of a binary system, the cloud can be disrupted and the particles transition from one state of the atom to another. In this talk, I will analyze a new gravitational signal that originates from the time dependent quadrupole moments of the gravitational atom and discuss observational prospects with the future space-based interferometer LISA.
