Unified remnant models for aligned-spin, precessing, and eccentric binary black hole mergers
Tousif Islam, Digvijay Wadekar, Gaurav Khanna
Using approximately numerical-relativity (NR) simulations spanning mass ratios up to and black-hole-perturbation-theory (BHPT) simulations extending to $q=100…
Modeling the merger-ringdown of an eccentric test-mass inspiral into a Kerr black hole using the effective-one-body framework
Guglielmo Faggioli, Alessandra Buonanno, Maarten van de Meent +1
We characterize and phenomenologically model the merger-ringdown of gravitational waves emitted by a small compact object that plunges and merges into a Kerr black hole from equato…
Advancing the Effective-One-Body Framework in the Test-Mass Limit
Nami Nishimura, Alessandra Buonanno, Guglielmo Faggioli +2
We present SEOB-TML, an enhanced effective-one-body (EOB) framework for the test-mass limit, optimized for quasi-circular, spin-aligned binary black holes. On the dynamical side, w…
Analysis of late-time tails in spin-aligned eccentric binary black hole mergers
Tousif Islam, Guglielmo Faggioli, Gaurav Khanna
We present a comprehensive analysis of late-time tails in gravitational radiation from merging spin-aligned eccentric binary black holes, using high-accuracy point-particle black h…
Consistency of spin effects between numerical relativity and perturbation theory for inspiraling comparable-mass black hole binaries
Tousif Islam, Gaurav Khanna, Scott E. Field
Numerical relativity (NR) provides the most accurate waveforms for comparable-mass binary black holes but becomes prohibitively expensive for increasingly asymmetric mass ratios. P…
Peaking into the abyss: Characterizing the merger of equatorial-eccentric-geodesic plunges in rotating black holes
Guglielmo Faggioli, Maarten van de Meent, Alessandra Buonanno +1
We study the gravitational waveforms generated by critical, equatorial plunging geodesics of the Kerr metric that start from an unstable-circular-orbit, which describe the test-mas…
Adding higher-order spherical harmonics in non-spinning eccentric binary black hole merger waveform models
Tousif Islam, Gaurav Khanna, Scott E. Field
gwNRHME is a recently developed framework that seamlessly converts a multi-modal (i.e with several spherical harmonic modes) quasi-circular waveform into multi-modal eccentric wave…
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…
Testing eccentric corrections to the radiation-reaction force in the test-mass limit of effective-one-body models
Guglielmo Faggioli, Maarten van de Meent, Alessandra Buonanno +3
In this work, we test an effective-one-body radiation-reaction force for eccentric planar orbits of a test mass in a Kerr background, which contains third-order post-Newtonian (PN)…
Binary Black Hole Coalescence Phenomenology from Numerical Relativity
Richard H. Price, Ritesh Bachhar, Gaurav Khanna
The major source of ground-based gravitational wave detectors, the inspiral and merger of comparable mass binary black holes (BBH), consists of a slow quasicircular inspiral, a mer…
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…
