Accelerated parameter estimation in Bilby with relative binning
Kruthi Krishna, Aditya Vijaykumar, Apratim Ganguly +5
We describe an implementation of the relative binning technique to speed up parameter estimation of gravitational-wave signals. We first give a pedagogical overview of relative bin…
Probing Correlations in the Binary Black Hole Population with Flexible Models
Jack Heinzel, Sylvia Biscoveanu, Salvatore Vitale
The astrophysical formation channels of binary black hole systems predict correlations between their mass, spin, and redshift distributions, which can be probed with gravitational-…
A Joint Fermi-GBM and Swift-BAT Analysis of Gravitational-Wave Candidates from the Third Gravitational-wave Observing Run
C. Fletcher, J. Wood, R. Hamburg +1696
We present Fermi Gamma-ray Burst Monitor (Fermi-GBM) and Swift Burst Alert Telescope (Swift-BAT) searches for gamma-ray/X-ray counterparts to gravitational wave (GW) candidate even…
Search for Eccentric Black Hole Coalescences during the Third Observing Run of LIGO and Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1772
Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Or…
Characterizing Gravitational Wave Detector Networks: From A to Cosmic Explorer
Ish Gupta, Chaitanya Afle, K. G. Arun +44
Gravitational-wave observations by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo have provided us a new tool to explore the Universe on all scales from n…
An observational upper limit on the rate of gamma-ray bursts with neutron star-black hole merger progenitors
Sylvia Biscoveanu, Eric Burns, Philippe Landry +1
Compact-object binary mergers consisting of one neutron star and one black hole (NSBHs) have long been considered promising progenitors for gamma-ray bursts, whose central engine r…
