"David Defeats Goliath: How Ultralight Fields Affect The Dynamics of Massive Black Holes"

Paolo Pani
Centro Multidisciplinar de Astrofísica, Instituto Superior Técnico (Lisbonne, Portugal)

In the last few years several interesting phenomena associated to the interaction between massive black holes and fundamental bosonic fields have been discovered. I present a selection of them, including superradiance instabilities of spin-0, spin-1 and spin-2 fields, floating orbits in extreme-mass ratio inspirals and black-hole spontaneous scalarization. The theoretical potential of these effects as almost-model-independent smoking guns for exotic particles and modified gravity, as well as their limitations in realistic astrophysical scenarios, are discussed.
