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…

Self-Gravity Effects of Ultralight Boson Clouds Formed by Black Hole Superradiance
Taillte May, William E. East, Nils Siemonsen
Oscillating clouds of ultralight bosons can grow around spinning black holes through superradiance, extracting energy and angular momentum, and eventually dissipating through gravi…

Nonlinear treatment of a black hole mimicker ringdown
Nils Siemonsen
We perform the first nonlinear and self-consistent study of the merger and ringdown of a black hole mimicking object with stable light rings. To that end, we numerically solve the…
