Ten years of extreme gravity tests of general theory of relativity with gravitational-wave observations
Anuradha Gupta
Ten years ago, the first direct detection of gravitational waves (GWs) from the merger of two black holes, GW150914, provided the very first opportunity to test Einstein's general…

Tracing the evolution of eccentric precessing binary black holes: a hybrid approach
Amitesh Singh, Nathan K. Johnson-McDaniel, Anuradha Gupta +1
To describe a general bound binary black hole system, we need to consider orbital eccentricity and the misalignment of black holes' spin vectors with respect to the orbital angular…

Evolution of precessing binary black holes on eccentric orbits using orbit-averaged evolution equations
Khun Sang Phukon, Nathan K. Johnson-McDaniel, Amitesh Singh +1
The most general bound binary black hole (BBH) system has an eccentric orbit and precessing spins. The detection of such a system with significant eccentricity close to the merger…
