Gravitational waves from black hole emission
Tousif Islam, Gaurav Khanna, Steven L. Liebling
Using adiabatic point-particle black hole perturbation theory, we simulate plausible gravitational wave~(GW) signatures in two exotic scenarios (i) where a small black hole is emit…
Gravitational wave surrogate model for spinning, intermediate mass ratio binaries based on perturbation theory and numerical relativity
Katie Rink, Ritesh Bachhar, Tousif Islam +6
We present BHPTNRSur2dq1e3, a reduced order surrogate model of gravitational waves emitted from binary black hole (BBH) systems in the comparable to large mass ratio regime with al…
Phenomenology and origin of late-time tails in eccentric binary black hole mergers
Tousif Islam, Guglielmo Faggioli, Gaurav Khanna +3
We investigate the late-time tail behavior in gravitational waves from merging eccentric binary black holes (BBH) using black hole perturbation theory. For simplicity, we focus onl…
Mapping between black-hole perturbation theory and numerical relativity II: gravitational-wave momentum
Tousif Islam
We report an approximate, non-trivial mapping of angular (linear) momentum in gravitational waves obtained from numerical relativity (NR) and adiabatic point-particle black hole pe…
