Constraining gravitational wave amplitude birefringence and Chern-Simons gravity with GWTC-2
We perform a new test of general relativity (GR) with signals from GWTC-2, the LIGO and Virgo catalog of gravitational wave detections. We search for the...
Integrability of eccentric, spinning black hole binaries up to second post-Newtonian order
We show that an eccentric binary of black holes with misaligned spins is integrable at 2PN order. We also construct 4 out of 5 action variables at 1.5PN.
Brans-Dicke theory in Bondi-Sachs form: Asymptotically flat solutions, asymptotic symmetries and gravitational-wave memory effects
We study the structure of asymptotic null infinity in the Brans-Dicke theory of gravity
A fixed point for black hole distributions
Merger dynamics create an attractive fixed-point in the space of distributions
