Deep Search for Joint Sources of Gravitational Waves and High-Energy Neutrinos with IceCube During the Third Observing Run of LIGO and Virgo

The IceCube Collaboration, R. Abbasi, M. Ackermann, J. Adams et autres

The discovery of joint sources of high-energy neutrinos and gravitational waves has been a primary target for the LIGO, Virgo, KAGRA, and IceCube observatories. The joint detection of high-energy neutrinos and gravitational waves would provide insight into cosmic processes, from the dynamics …

Constraints on Gravitational Waves from the 2024 Vela Pulsar Glitch

A.G Abac, R Abbott, I. Abouelfettouh, F. Acernese et autres

Abstract Among known neutron stars, the Vela pulsar is one of the best targets for gravitational-wave searches. It is also one of the most prolific in terms of glitches, which are sudden frequency changes in a pulsar’s rotation. Such glitches could cause …

Searches for Continuous Gravitational Waves from Supernova Remnants in the First Part of the LIGO-Virgo-KAGRA Fourth Observing Run

A. Abac, R Abbott, I. Abouelfettouh, F. Acernese et autres

Abstract We present results from directed searches for continuous gravitational waves from a sample of 15 nearby supernova remnants, likely hosting young neutron star candidates, using data from the first eight months of the fourth observing run (O4) of the LIGO–Virgo–KAGRA Collaboration. …

GW231123: A Binary Black Hole Merger with Total Mass 190265 M⊙

A. G. Abac, R. Abbott, I. Abouelfettouh, F. Acernese et autres

On 2023 November 23, the two LIGO observatories both detected GW231123, a gravitational-wave signal consistent with the merger of two black holes with masses 137−18+23M⊙ and 101−50+22M⊙ (90% credible intervals), at a luminosity distance of 0.7–4.1 Gpc, a redshift of 0.40−0.25+0.27 , …
