Search for continuous gravitational waves directed at sub-threshold radiometer candidates in O3 LIGO data
Alan M. Knee, Helen Du, Evan Goetz +7
We present results of a follow-up search for continuous gravitational waves (CWs) associated with sub-threshold candidates from the LIGO-Virgo-KAGRA (LVK) All-Sky All-Frequency (AS…
Search for Eccentric Black Hole Coalescences during the Third Observing Run of LIGO and Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1772
Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Or…
Rotational and radio emission properties of PSR J0738-4042 over half a century
M. E. Lower, S. Johnston, A. Karastergiou +14
We present a comprehensive study of the rotational and emission properties of PSR J07384042 using a combination of observations taken by the Deep Space Network, Hartebeesthoek,…
A new small glitch in Vela discovered with a hidden Markov model
L. Dunn, A. Melatos, C. M. Espinoza +2
A striking feature of the Vela pulsar (PSR J08354510) is that it undergoes sudden increases in its spin frequency, known as glitches, with a fractional amplitude on the order of…
Search for gravitational-lensing signatures in the full third observing run of the LIGO-Virgo network
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1692
Gravitational lensing by massive objects along the line of sight to the source causes distortions of gravitational wave-signals; such distortions may reveal information about funda…
The 2022 high-energy outburst and radio disappearing act of the magnetar 1E 1547.0-5408
Marcus E. Lower, George Younes, Paul Scholz +19
We report the radio and high-energy properties of a new outburst from the radio-loud magnetar 1E 1547.05408. Following the detection of a short burst from the source with Swift-…
Open data from the third observing run of LIGO, Virgo, KAGRA and GEO
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1741
The global network of gravitational-wave observatories now includes five detectors, namely LIGO Hanford, LIGO Livingston, Virgo, KAGRA, and GEO 600. These detectors collected data…
Search for subsolar-mass black hole binaries in the second part of Advanced LIGO's and Advanced Virgo's third observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1702
We describe a search for gravitational waves from compact binaries with at least one component with mass 0.2 -- and mass ratio in Advanced LIGO…

Deeksha Beniwal, Patrick Clearwater, Liam Dunn +4
We present a search for continuous gravitational wave signals from an unidentified pulsar potentially powering HESS~J1427-608, a spatially unresolved TeV point source detected by t…
Model-based cross-correlation search for gravitational waves from the low-mass X-ray binary Scorpius X-1 in LIGO O3 data

We present the results of a model-based search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1 using LIGO detector data from the third observing run…
Validating continuous gravitational-wave candidates from a semicoherent search using Doppler modulation and an effective point spread function
Dana Jones, Ling Sun, Julian Carlin +9
Following up large numbers of candidates in continuous gravitational wave searches presents a challenge, particularly in regard to computational power and the time required to manu…
