Ultralight boson constraints from gravitational wave observations of spinning binary black holes
P. S. Aswathi, William E. East, Nils Siemonsen +2
In the presence of an ultralight scalar or vector boson, a spinning black hole will be spun down through the superradiant instability. We use spin measurements from gravitational w…

Methodology for constraining ultralight vector bosons with gravitational wave searches targeting merger remnant black holes
Dana Jones, Nils Siemonsen, Ling Sun +4
Ultralight bosons are a hypothetical class of particles predicted under various extensions of Standard Model physics. As a result of the superradiance mechanism, we expect ultralig…
