Searching for ultralight bosons with black holes and gravitational waves
Richard Brito (Instituto Superior Técnico in Lisbon)
Description :

Ultralight bosons are compelling dark-matter candidates and arise in a variety of beyond-Standard-Model scenarios. These fields can tap energy and angular momentum from spinning black holes through a process known as "black hole superradiance", during which a macroscopic bosonic condensate develops around the black hole. Striking signatures of this phenomenon that have been studied over the past few years include for example: gaps in the spin-mass distribution of astrophysical black holes, the emission of continuous gravitational-wave signals and signatures in the gravitational waves emitted by binary black holes, opening the exciting possibility to search for extremely light particles using current and future observations of black holes and gravitational waves. In this talk I will give an overview of the status of this research program.
