LIGO Detector Characterization in the Second and Third Parts of the Fourth Observing Run
J. Glanzer, A. F. Helmling-Cornell, A. Calafat +244
LIGO detector characterization efforts enabled the confident detection of gravitational waves from hundreds of compact binary coalescences during the fourth observing run. Reliable…
The G347.3-0.5 outlier from O3: a follow-up case study for continuous gravitational-wave candidates
L. Mirasola, F. Amicucci, M. Carrio +31
We report a multi-pipeline follow-up study of the continuous gravitational-wave (CW) outlier identified by the Ming et al. Einstein@Home directed search for the young supernova rem…
Spotlight searches for continuous gravitational waves triggered on radiometer candidates in LIGO O4a data
Alan M. Knee, Keith Riles, Ling Sun
We report on a follow-up search for continuous gravitational waves (CWs) targeting sub-threshold candidates from the O4a LIGO-Virgo-KAGRA (LVK) all-sky all-frequency (ASAF) directe…
Narrow spectral artifact investigation and mitigation in LIGO data from the fourth LIGO-Virgo-KAGRA observing run
E. Goetz, A. Neunzert, A. M. Knee +260
We present efforts to identify, characterize, and mitigate narrow spectral artifacts in LIGO detector data during the fourth LIGO-Virgo-KAGRA observing run. Narrow spectral artifac…
Extracting Astrophysical Information of Highly-Eccentric Binaries in the Millihertz Gravitational Wave Band
Zeyuan Xuan, Smadar Naoz, Alvin K. Y. Li +6
Wide, highly eccentric () compact binaries can naturally arise as progenitors of gravitational wave (GW) mergers. These systems are expected to have a significant population…
Coalescing Compact Binary Parameter Estimation with Gravitational Waves in the Presence of non-Gaussian Transient Noise
Yannick Lecoeuche, Jess McIver, Alan M. Knee +7
Data from gravitational-wave (GW) detectors often contains a high rate of non-Gaussian transient noise, known as glitches. The parameters estimated from GW signals coinciding with…
