GW231123: A Binary Black Hole Merger with Total Mass 190–265 M ⊙

Adrian Abac, I. Abouelfettouh, F. Acernese, K. Ackley et autres

Abstract 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 13 7 − 18 + 23 M ⊙ and 10 1 − 50 + 22 M ⊙ …

Directed searches for gravitational waves from ultralight vector boson clouds around merger remnant and galactic black holes during the first part of the fourth LIGO-Virgo-KAGRA observing run

The LIGO Scientific Collaboration, the KAGRA Collaboration, K. Ackley, S Adhicary et autres

We present the first directed searches for long-transient and continuous gravitational waves from ultralight vector boson clouds around known black holes (BHs). We use LIGO data from the first part of the fourth LIGO-Virgo-KAGRA observing run. The searches target two distinct types …

Search for Gravitational Waves Emitted from SN 2023ixf

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

Abstract We present the results of a search for gravitational-wave transients associated with core-collapse supernova SN 2023ixf, which was observed in the galaxy Messier 101 via optical emission on 2023 May 19, during the LIGO–Virgo–KAGRA 15th Engineering Run. We define a five-day …

Search for Gravitational-lensing Signatures in the Full Third Observing Run of the LIGO–Virgo Network

R. Abbott, H. Abe, F. Acernese, K. Ackley et autres

Abstract Gravitational lensing by massive objects along the line of sight to the source causes distortions to gravitational wave (GW) signals; such distortions may reveal information about fundamental physics, cosmology, and astrophysics. In this work, we have extended the search for lensing …

GWTC-3: Compact Binary Coalescences Observed by LIGO and Virgo During the Second Part of the Third Observing Run

The LIGO Scientific Collaboration, the KAGRA Collaboration, R. Abbott, T. D. Abbott et autres

The third Gravitational-Wave Transient Catalog (GWTC-3) describes signals detected with Advanced LIGO and Advanced Virgo up to the end of their third observing run. Updating the previous GWTC-2.1, we present candidate gravitational waves from compact binary coalescences during the second half of …
