Eccentricity-induced systematic error on parametrized tests of general relativity: Hierarchical Bayesian inference applied to a binary black hole population
Pankaj Saini, Sajad A. Bhat, Marc Favata +1
One approach to testing general relativity (GR) introduces free parameters in the post-Newtonian (PN) expansion of the gravitational-wave (GW) phase. If systematic errors on these…
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…
Testing general relativity via direct measurement of black hole kicks
Parthapratim Mahapatra, Marc Favata, K. G. Arun
Asymmetric emission of gravitational waves during a compact binary coalescence results in the loss of linear momentum and a corresponding "kick" or recoil on the binary's center of…
Search for gravitational-lensing signatures in the full third observing run of the LIGO-Virgo network
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1692
Gravitational lensing by massive objects along the line of sight to the source causes distortions of gravitational wave-signals; such distortions may reveal information about funda…
Open data from the third observing run of LIGO, Virgo, KAGRA and GEO
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1741
The global network of gravitational-wave observatories now includes five detectors, namely LIGO Hanford, LIGO Livingston, Virgo, KAGRA, and GEO 600. These detectors collected data…
