Black hole superradiance of self-interacting scalar fields
Masha Baryakhtar, Marios Galanis, Robert Lasenby +1
Black hole superradiance is a powerful probe of light, weakly-coupled hidden sector particles. Many candidate particles, such as axions, generically have self-interactions that can…

The Large-Misalignment Mechanism for the Formation of Compact Axion Structures: Signatures from the QCD Axion to Fuzzy Dark Matter
Asimina Arvanitaki, Savas Dimopoulos, Marios Galanis +3
Axions are some of the best motivated particles beyond the Standard Model. We show how the attractive self-interactions of dark matter (DM) axions over a broad range of masses, fro…
