Accurate models for recoil velocity distribution in black hole mergers with comparable to extreme mass-ratios and their astrophysical implications
Tousif Islam, Digvijay Wadekar
Modeling the remnant recoil velocity (kick) distribution from binary black hole mergers is crucial for understanding hierarchical mergers in active galactic nuclei or globular clus…
Data-driven extraction and phenomenology of eccentric harmonics in eccentric spinning binary black hole mergers
Tousif Islam, Tejaswi Venumadhav, Ajit Kumar Mehta +6
Newtonian and post-Newtonian (PN) calculations indicate that the phenomenology of eccentric binary black hole (BBH) merger waveforms is significantly more complex than that of thei…
Binary black hole population inference combining confident and marginal events from the search pipeline
Ajit Kumar Mehta, Digvijay Wadekar, Isha Anantpurkar +6
We present the population properties of binary black hole mergers identified by the pipeline (which incorporates higher-order modes in the search templates) du…
Improving gravitational wave search sensitivity with TIER: Trigger Inference using Extended strain Representation
Digvijay Wadekar, Arush Pimpalkar, Mark Ho-Yeuk Cheung +9
We introduce a machine learning (ML) framework called for improving the sensitivity of gravitational wave search pipelines. Typically, search pipelines only use a s…
Searching for intermediate mass ratio binary black hole mergers in the third observing run of LIGO-Virgo-KAGRA
Mark Ho-Yeuk Cheung, Digvijay Wadekar, Ajit Kumar Mehta +6
Intermediate mass ratio inspirals (IMRIs) of binary black holes with mass ratios are astrophysically interesting sources of gravitational waves. Me…
gwharmone: first data-driven surrogate for eccentric harmonics in binary black hole merger waveforms
Tousif Islam, Tejaswi Venumadhav, Ajit Kumar Mehta +6
We present gwharmone, the first data-driven surrogate model for eccentric harmonics (as well as the full radiation content) of the dominant quadrupolar mode in eccentric, non-spinn…
GWSurrogate: A Python package for gravitational wave surrogate models
Scott E. Field, Vijay Varma, Jonathan Blackman +9
Fast and accurate waveform models are fundamentally important to modern gravitational wave astrophysics, enabling the study of merging compact objects like black holes and neutron…
Data-driven extraction, phenomenology and modeling of eccentric harmonics in binary black hole merger waveforms
Tousif Islam, Tejaswi Venumadhav, Ajit Kumar Mehta +6
Newtonian and post-Newtonian (PN) calculations suggest that each spherical harmonic mode of the gravitational waveforms (radiation) emitted by eccentric binaries can be further dec…
Significant increase in sensitive volume of a gravitational wave search upon including higher harmonics
Ajit Kumar Mehta, Digvijay Wadekar, Javier Roulet +6
Most gravitational wave searches to date have included only the quadrupole mode in their search templates. Here, we demonstrate that incorporating higher harmonics improves the sea…
Post-Newtonian theory-inspired framework for characterizing eccentricity in gravitational waveforms
Tousif Islam, Tejaswi Venumadhav
Characterizing eccentricity in gravitational waveforms in a consistent manner is crucial to facilitate parameter estimation, astrophysical population studies, as well as searches f…
