GWTC-4.0: Constraints on the Cosmic Expansion Rate and Modified Gravitational-wave Propagation

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

Abstract We analyze data from 142 of the 218 gravitational-wave (GW) sources in the fourth LIGO–Virgo–KAGRA Collaboration (LVK) Gravitational-Wave Transient Catalog (GWTC-4.0) to estimate the Hubble constant H 0 jointly with the population properties of merging compact binaries. We measure the luminosity …

GWTC-4.0: Population Properties of Merging Compact Binaries

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

Abstract We detail the population properties of binary neutron star, neutron star–black hole binary, and binary black hole mergers using 158 events from the cumulative Gravitational-Wave Transient Catalog 4.0. The black hole primary mass distribution consists of a power-law-like continuum that steepens …

Constraints on Gravitational Waves from the 2024 Vela Pulsar Glitch

Adrian Abac, I. Abouelfettouh, F. Acernese, K. Ackley 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 …

Open Data from LIGO, Virgo, and KAGRA through the First Part of the Fourth Observing Run

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

Abstract LIGO, Virgo, and KAGRA form a network of gravitational-wave observatories. Data and analysis results from this network are made publicly available through the Gravitational Wave Open Science Center. This paper describes open data from this network, including the addition of data …

GWTC-4.0: Updating the Gravitational-wave Transient Catalog with Observations from the First Part of the Fourth LIGO–Virgo–KAGRA Observing Run

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

Abstract Version 4.0 of the Gravitational-Wave Transient Catalog (GWTC-4.0) adds new candidates detected by the LIGO, Virgo, and KAGRA observatories through the first part of the fourth observing run (O4a: 2023 May 24 15:00:00 to 2024 January 16 16:00:00 UTC) and a …
