Black hole superradiance may aid quest for dark matter | Space Superradiance can operate on dark photons just as well as it does on normal photons When dark photons collect around black holes, they can get trapped and boosted to high energies, where
Superradiance of rotating black holes surrounded by dark matter In rotating black hole background surrounded by dark matter, we investigated the super-radiant phenomenon of massive scalar field and its associated instability Using the method of asymptotic matching, we computed the amplification factor of scalar wave scattering to assess the strength of super-radiance
Black hole superradiance with dark matter accretion Studies of black hole superradiance often focus on the growth of a cloud in isolation, accompanied by the spin-down of the black hole In this paper, we consider the additional effect of the accretion of matter and angular momentum from the environment
Superradiance: New Frontiers in Black Hole Physics - Springer This book focuses on rotational superradiance which is one of the most interesting mechanism in black hole physics, leading to Penrose processes, black-hole bombs, and Hawking radiation It provides important applications in dark matter searches and in physics beyond the standard model

Black-hole superradiance - KIAS HEP Events (Indico) Black-hole superradiance: probing the dark universe with compact objects and GWs overview: Brito, Cardoso, Pani, “Superradiance” – Springer Lect Notes Phys 971 (2020) gr-qc 1501 06570 (latest update on Jan 2021 and counting)
[2504. 18935] Superradiant dark matter production from primordial black . . . Superradiance leads to an exponential growth of particle occupation numbers in gravitationally bound states We present an analysis of heavy bosonic dark matter (DM) production through three gravitational mechanisms: Hawking radiation, superradiant instabilities, and ultraviolet (UV) freeze-in
Scientists code Milky Way twin galaxies to better understand dark matter Scientists code Milky Way twin galaxies to better understand dark matter USC researchers led the development of a computer simulation that gives astrophysicists a mechanism for testing ideas about dark matter and its behavior in the Milky Way and other galaxies
