Photon Calibration Performance of KAGRA during the 4th Joint Observing Run (O4)
Dan Chen, Shingo Hido, Darkhan Tuyenbayev +9
KAGRA is a kilometer-scale cryogenic gravitational-wave (GW) detector in Japan. It joined the 4th joint observing run (O4) in May 2023 in collaboration with the Laser Interferomete…
Performance of the KAGRA detector during the first joint observation with GEO 600 (O3GK)
KAGRA Collaboration, H. Abe, R. X. Adhikari +212
KAGRA, the kilometer-scale underground gravitational-wave detector, is located at Kamioka, Japan. In April 2020, an astrophysics observation was performed at the KAGRA detector in…
Application of the independent component analysis to the iKAGRA data
KAGRA Collaboration, T. Akutsu, M. Ando +244
We apply the independent component analysis (ICA) to the real data from a gravitational wave detector for the first time. Specifically we use the iKAGRA data taken in April 2016, a…
Improving astrophysical parameter estimation via offline noise subtraction for Advanced LIGO
J. C. Driggers, S. Vitale, A. P. Lundgren +228
The Advanced LIGO detectors have recently completed their second observation run successfully. The run lasted for approximately 10 months and lead to multiple new discoveries. The…
Identification and mitigation of narrow spectral artifacts that degrade searches for persistent gravitational waves in the first two observing runs of Advanced LIGO
P. B. Covas, A. Effler, E. Goetz +260
Searches are under way in Advanced LIGO and Virgo data for persistent gravitational waves from continuous sources, e.g. rapidly rotating galactic neutron stars, and stochastic sour…
Reconstructing the calibrated strain signal in the Advanced LIGO detectors
A. D. Viets, M. Wade, A. L. Urban +14
Advanced LIGO's raw detector output needs to be calibrated to compute dimensionless strain h(t). Calibrated strain data is produced in the time domain using both a low-latency, onl…
Calibration Uncertainty for Advanced LIGO's First and Second Observing Runs
Craig Cahillane, Joe Betzwieser, Duncan A. Brown +13
Calibration of the Advanced LIGO detectors is the quantification of the detectors' response to gravitational waves. Gravitational waves incident on the detectors cause phase shifts…
Effects of transients in LIGO suspensions on searches for gravitational waves
M. Walker, T. D. Abbott, S. M. Aston +200
This paper presents an analysis of the transient behavior of the Advanced LIGO suspensions used to seismically isolate the optics. We have characterized the transients in the longi…
The Advanced LIGO Photon Calibrators
S. Karki, D. Tuyenbayev, S. Kandhasamy +24
The two interferometers of the Laser Interferometry Gravitaional-wave Observatory (LIGO) recently detected gravitational waves from the mergers of binary black hole systems. Accura…
Improving LIGO calibration accuracy by tracking and compensating for slow temporal variations
D. Tuyenbayev, S. Karki, J. Betzwieser +9
Calibration of the second-generation LIGO interferometric gravitational-wave detectors employs a method that uses injected periodic modulations to track and compensate for slow tem…
