Placing Limits on Light Axions with EHT Polarimetry via Closure Traces
(University of Waterloo, 2023-08-31)Black holes can amplify incoming bosonic waves via rotational superradiance, inducing bound states of ultralight bosons around them. This phenomenon has the potential to confine the parameter spaces of new bosons. Axions, ...
