GW241011 and GW241110: Exploring Binary Formation and Fundamental Physics with Asymmetric, High-Spin Black Hole Coalescence
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1783
We report the observation of gravitational waves from two binary black hole coalescences during the fourth observing run of the LIGO--Virgo--KAGRA detector network, GW241011 and GW…
Dark photon superradiance: Electrodynamics and multimessenger signals
Nils Siemonsen, Cristina Mondino, Daniel Egana-Ugrinovic +3
We study the electrodynamics of a kinetically mixed dark photon cloud that forms through superradiance around a spinning black hole, and design strategies to search for the resulti…
SuperRad: Modeling the black hole superradiance gravitational waveform
Nils Siemonsen, Taillte May, William E. East
Gravitational signatures of black hole superradiance are a unique probe of ultralight particles that are weakly-coupled to ordinary matter. The existence of an ultralight boson wou…
