Integrated cosmological memory: A dark-siren method to probe dark energy
Indranil Chakraborty, Sayantan Ghosh, Susmita Jana +2
Gravitational-wave (GW) cosmology is currently bottlenecked by the scarcity of electromagnetic counterparts for bright sirens and the systematic uncertainties of galaxy catalogs fo…
Improving the detection significance of gravitational wave transient searches with CNN models
Johann Fernandes, Archana Pai, Koustav Chandra
Gravitational wave (GW) transient searches rely on signal-noise discriminators to distinguish astrophysical signals from noise artefacts. These discriminators are typically tuned t…
Unmasking noise transients masquerading as intermediate-mass black hole binaries
Sayantan Ghosh, Koustav Chandra, Archana Pai
In the first three observation runs, ground-based gravitational wave (GW) detectors have observed close to 100 compact binary coalescence (CBC) events. The GW detection rates for C…
Probing eccentric higher-order modes through an effective chirp mass model
Ravikiran Hegde, Nirban Bose, Archana Pai
The three observational runs of advanced LIGO and Virgo detectors have detected 90 compact binary coalescence events with most of them being quasicircular compact binary mer…
Impact of Bayesian Priors on the Inferred Masses of Quasi-Circular Intermediate-Mass Black Hole Binaries
Koustav Chandra, Archana Pai, Samson H. W. Leong +1
Observation of gravitational waves from inspiralling binary black holes has offered a unique opportunity to study the physical parameters of the component black holes. To infer the…
