Black Hole Quasinormal Mode Resonances and Reconnections in Coupled Systems
Leah Jenks, Hayato Motohashi, Kazufumi Takahashi +2
Black hole quasinormal modes (QNMs) provide a window into the underlying structure of black holes and the environments in which they arise. QNMs have particularly rich dynamics in…
Gravitational Waves in Chern-Simons-Gauss-Bonnet Gravity
Tatsuya Daniel, Leah Jenks, Stephon Alexander
It is known that the four-dimensional effective field theory arising from heterotic string theory is general relativity with both a Chern-Simons and Gauss-Bonnet term. We study the…
Birefringence tests of gravity with multi-messenger binaries
Macarena Lagos, Leah Jenks, Maximiliano Isi +7
Extensions to General Relativity (GR) allow the polarization of gravitational waves (GW) from astrophysical sources to suffer from amplitude and velocity birefringence, which respe…
A New Probe of Gravitational Parity Violation Through (Non-)Observation of the Stochastic Gravitational-Wave Background
Thomas Callister, Leah Jenks, Daniel Holz +1
Parity violation in the gravitational sector is a prediction of many theories beyond general relativity. In the propagation of gravitational waves, parity violation manifests by in…
Parameterized Parity Violation in Gravitational Wave Propagation
Leah Jenks, Lyla Choi, Macarena Lagos +1
Gravitational parity violation arises in a variety of theories beyond general relativity. Gravitational waves in such theories have their propagation altered, leading to birefringe…
Black Hole Superradiance in Dynamical Chern-Simons Gravity
Stephon Alexander, Gregory Gabadadze, Leah Jenks +1
Black hole superradiance provides a window into the dynamics of light scalar fields and their interactions close to a rotating black hole. Due to the rotation of the black hole, th…
Probing Noncommutative Gravity with Gravitational Wave and Binary Pulsar Observations
Leah Jenks, Kent Yagi, Stephon Alexander
Noncommutative gravity is a natural method of quantizing spacetime by promoting the spacetime coordinates themselves to operators which do not commute. This approach is motivated,…
Gravity waves in parity-violating Copernican Universes
Stephon Alexander, Leah Jenks, Pavel Jiroušek +2
In recent work minimal theories allowing the variation of the cosmological constant by means of a balancing torsion, have been proposed. It was found that such theories contain par…
