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…
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…
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 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…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
