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…
Sampler-free gravitational wave inference using matrix multiplication
Jonathan Mushkin, Javier Roulet, Barak Zackay +5
Parameter estimation (PE) for compact binary coalescence (CBC) events observed by gravitational wave (GW) laser interferometers is a core task in GW astrophysics. We present a meth…
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…
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…
