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, P. Vereš et autres

Abstract 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 events identified during the third observing run of the Advanced LIGO and Advanced Virgo detectors. Using Fermi-GBM onboard triggers and …

Tests of General Relativity with GWTC-3

The LIGO Scientific Collaboration, the KAGRA Collaboration, R. Abbott, H. Abe et autres

The ever-increasing number of detections of gravitational waves (GWs) from compact binaries by the Advanced LIGO and Advanced Virgo detectors allows us to perform ever-more sensitive tests of general relativity (GR) in the dynamical and strong-field regime of gravity. We perform a …

All-sky search for gravitational wave emission from scalar boson clouds around spinning black holes in LIGO O3 data

The LIGO Scientific Collaboration, the KAGRA Collaboration, R. Abbott, H. Abe et autres

This paper describes the first all-sky search for long-duration, quasi-monochromatic gravitational-wave signals emitted by ultralight scalar boson clouds around spinning black holes using data from the third observing run of Advanced LIGO. We analyze the frequency range from 20~Hz to 610~Hz, over …

Search for intermediate-mass black hole binaries in the third observing run of Advanced LIGO and Advanced Virgo

R. Abbott, T. D. Abbott, F. Acernese, K. Ackley et autres

Intermediate-mass black holes (IMBHs) span the approximate mass range 100−105 M⊙, between black holes (BHs) that formed by stellar collapse and the supermassive BHs at the centers of galaxies. Mergers of IMBH binaries are the most energetic gravitational-wave sources accessible by the …

Upper limits on the isotropic gravitational-wave background from Advanced LIGO and Advanced Virgo’s third observing run

R. Abbott, T. D. Abbott, S. Abraham, F. Acernese et autres

We report results of a search for an isotropic gravitational-wave background (GWB) using data from Advanced LIGO's and Advanced Virgo's third observing run (O3) combined with upper limits from the earlier O1 and O2 runs. Unlike in previous observing runs in the …
