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 …

All-sky search for short gravitational-wave bursts in the third Advanced LIGO and Advanced Virgo run

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

This paper presents the results of a search for generic short-duration gravitational-wave transients in data from the third observing run of Advanced LIGO and Advanced Virgo. Transients with durations of milliseconds to a few seconds in the 24--4096 Hz frequency band are …

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 …

Constraints on cosmic strings using data from the first Advanced LIGO observing run

B. P. Abbott, R. Abbott, T. D. Abbott, F. Acernese et autres

Cosmic strings are topological defects which can be formed in grand unified theory scale phase transitions in the early universe. They are also predicted to form in the context of string theory. The main mechanism for a network of Nambu-Goto cosmic strings …

First low-frequency Einstein@Home all-sky search for continuous gravitational waves in Advanced LIGO data

B. P. Abbott, R. Abbott, T. D. Abbott, F. Acernese et autres

We report results of a deep all-sky search for periodic gravitational waves from isolated neutron stars in data from the first Advanced LIGO observing run. This search investigates the low frequency range of Advanced LIGO data, between 20 and 100 Hz, much …

Search for continuous gravitational waves from neutron stars in globular cluster NGC 6544

B. P. Abbott, R. Abbott, T. D. Abbott, M. R. Abernathy et autres

We describe a directed search for continuous gravitational waves in data from the sixth initial LIGO science run. The target was the nearby globular cluster NGC 6544 at a distance of $\ensuremath{\approx}2.7\text{ }\text{ }\mathrm{kpc}$. The search covered a broad band of frequencies …
