Comparing numerical relativity and perturbation theory waveforms for a non-spinning equal-mass binary
Tousif Islam, Scott E. Field, Gaurav Khanna
Past studies have empirically demonstrated a surprising agreement between gravitational waveforms computed using adiabatic-driven-inspiral point-particle black hole perturbation th…
Mapping between black-hole perturbation theory and numerical relativity: gravitational-wave energy flux
Tousif Islam
We investigate the - mapping, as previously introduced by Islam et al.~\cite{Islam:2022laz}, which relates numerical relativity (NR) and adiabatic point-particle black hole p…
Analysis of GWTC-3 with fully precessing numerical relativity surrogate models
Tousif Islam, Avi Vajpeyi, Feroz H. Shaik +6
The third Gravitational-Wave Transient Catalog (GWTC-3) contains 90 binary coalescence candidates detected by the LIGO-Virgo-KAGRA Collaboration (LVK). We provide a re-analysis of…
On the approximate relation between black-hole perturbation theory and numerical relativity
Tousif Islam, Gaurav Khanna
We investigate the interplay between numerical relativity (NR) and adiabatic point-particle black hole perturbation theory (ppBHPT) in the comparable mass regime for quasi-circular…
Interplay between numerical-relativity and black hole perturbation theory in the intermediate-mass-ratio regime
Tousif Islam
We investigate the interplay between numerical relativity (NR) and point-particle black hole perturbation theory (ppBHPT) for quasi-circular non-spinning binary black holes in the…
Interplay between numerical relativity and perturbation theory : finite size effects
Tousif Islam, Gaurav Khanna
We investigate the interplay between numerical relativity (NR) and point-particle black hole perturbation theory (ppBHPT) in the comparable mass ratio regime. In the ppBHPT framewo…
Remnant black hole properties from numerical-relativity-informed perturbation theory and implications for waveform modelling
Tousif Islam, Scott E. Field, Gaurav Khanna
During binary black hole (BBH) mergers, energy and momenta are carried away from the binary system as gravitational radiation. Access to the radiated energy and momenta allows us t…
White dwarf mass-radius relation in theories beyond general relativity
Khursid Alam, Tousif Islam
We explore the internal structures of the white dwarfs in two different modified theories of gravity: (i) scalar-tensor-vector gravity and (ii) beyond Horndeski theories of t…
