Linear stability of nonbidiagonal black holes in massive gravity
Eugeny Babichev, Richard Brito, Paolo Pani
We consider generic linear perturbations of a nonbidiagonal class of static black-hole solutions in massive (bi)gravity. We show that the quasinormal spectrum of these solutions co…
Accretion of dark matter by stars
Richard Brito, Vitor Cardoso, Hirotada Okawa
Searches for dark matter imprints are one of the most active areas of current research. We focus here on light fields with mass , such as axions and axion-like candidates. Usi…
Proca Stars: gravitating Bose-Einstein condensates of massive spin 1 particles
Richard Brito, Vitor Cardoso, Carlos A. R. Herdeiro +1
We establish that massive complex Abelian vector fields (mass ) can form gravitating solitons, when minimally coupled to Einstein's gravity. Such Proca stars (PSs) have a statio…
Superradiance in stars
Vitor Cardoso, Richard Brito, Joao L. Rosa
It has long been known that dissipation is a crucial ingredient in the superradiant amplification of wavepackets off rotating objects. We show that, once appropriate dissipation me…
Black holes in massive gravity
Eugeny Babichev, Richard Brito
We review the black hole solutions of the ghost-free massive gravity theory and its bimetric extension and outline the main results on the stability of these solutions against smal…
Superradiance -- the 2020 Edition
Richard Brito, Vitor Cardoso, Paolo Pani
Superradiance is a radiation enhancement process that involves dissipative systems. With a 60 year-old history, superradiance has played a prominent role in optics, quantum mechani…
