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…

Fuzzy Dark Matter and the 21cm Power Spectrum
Dana Jones, Skyler Palatnick, Richard Chen +2
We model the 21cm power spectrum across the Cosmic Dawn and the Epoch of Reionization (EoR) in fuzzy dark matter (FDM) cosmologies. The suppression of small mass halos in FDM model…
