Narrowband searches for continuous gravitational waves from known pulsars in the first two parts of the fourth LIGO--Virgo--KAGRA observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1853
Rotating non-axisymmetric neutron stars (NSs) are promising sources for continuous gravitational waves (CWs). Such CWs can, if detected, inform us about the internal structure and…
Mirror Surface Evaluation for the Einstein Telescope Using Virtual Mirror Maps
A. Bianchi, A. C. Green, J. Degallaix +3
The performance of mirrors in optical interferometers is critically influenced by their surface quality. Accurate metrology enables mirror surfaces to be characterized through phas…
Searches for Continuous Gravitational Waves from Supernova Remnants in the first part of the LIGO-Virgo-KAGRA Fourth Observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1764
We present results from directed searches for continuous gravitational waves from a sample of 15 nearby supernova remnants, likely hosting young neutron star candidates, using data…
GWTC-4.0: Tests of General Relativity. III. Tests of the Remnants
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1779
This is the third paper of the set recording the results of the suite of tests of general relativity (GR) performed on the signals from the fourth Gravitational-Wave Transient Cata…
GWTC-4.0: Tests of General Relativity. II. Parameterized Tests
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1785
In this second of three papers on tests of general relativity (GR) applied to the compact binary coalescence signals in the 4th Gravitational-Wave Transient Catalog (GWTC-4.0), we…
GWTC-4.0: Tests of General Relativity. I. Overview and General Tests
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1781
The worldwide LIGO-Virgo-KAGRA network of gravitational-wave (GW) detectors continues to increase in sensitivity, thus increasing the quantity and quality of the detected GW signal…
