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…
Black hole-neutron star mergers in Einstein-scalar-Gauss-Bonnet gravity
Maxence Corman, William E. East
Gravitational wave observations of black hole-neutron star binaries, particularly those where the black hole has a lower mass compared to other observed systems, have the potential…
Nonlinear effect of absorption on the ringdown of a spinning black hole
Taillte May, Sizheng Ma, Justin L. Ripley +1
The ringdown gravitational wave signal arising e.g., in the final stage of a black hole binary merger, contains important information about the properties of the remnant, and can p…
Nonlinear studies of modifications to general relativity: Comparing different approaches
Maxence Corman, Luis Lehner, William E. East +1
Studying the dynamical, nonlinear regime of modified theories of gravity remains a theoretical challenge that limits our ability to test general relativity. Here we consider two ge…
