Nonlinear Independent Component Analysis Scheme and its application to gravitational wave data analysis
Jun'ya Kume, Koh Ueno, Tatsuki Washimi +3
Noise subtraction is a crucial process in gravitational wave (GW) data analysis to improve the sensitivity of interferometric detectors. While linear noise coupling has been extens…
Response of the underground environment of the KAGRA observatory against the air-pressure disturbance from the Tonga volcano eruption on January 15th, 2022
T. Washimi, T. Yokozawa, A. Takamori +11
On January 15, 2022, at 04:14:45 (UTC), the Hunga Tonga-Funga Ha'apai, a submarine volcano in the Tongan archipelago in the southern Pacific Ocean, erupted and generated global sei…
Identifying multichannel coherent couplings and causal relationships in gravitational wave detectors
Piljong Jung, Sang Hoon Oh, Young-Min Kim +4
The gravitational-wave detector is a complex and sensitive collection of advanced instruments that are impacted not only by mechanical/electronics systems but also by the surroundi…
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…
The KAGRA underground environment and lessons for the Einstein Telescope
Francesca Badaracco, Camilla De Rossi, Irene Fiori +6
The KAGRA gravitational-wave detector in Japan is the only operating detector hosted in an underground infrastructure. Underground sites promise a greatly reduced contribution of t…
Design and experimental demonstration of a laser modulation system for future gravitational-wave detectors
Kohei Yamamoto, Keiko Kokeyama, Yuta Michimura +12
Detuning the signal-recycling cavity length from a cavity resonance significantly improves the quantum noise beyond the standard quantum limit, while there is no km-scale gravitati…
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…
First cryogenic test operation of underground km-scale gravitational-wave observatory KAGRA
KAGRA Collaboration, T. Akutsu, M. Ando +198
KAGRA is a second-generation interferometric gravitational-wave detector with 3-km arms constructed at Kamioka, Gifu in Japan. It is now in its final installation phase, which we c…
Improving the absolute accuracy of the gravitational wave detectors by combining the photon pressure and gravity field calibrators
Yuki Inoue, Sadakazu Haino, Nobuyuki Kanda +5
The absolute accuracy of the estimated parameters of gravitational wave sources will be fundamentally limited by the calibration uncertainties of the detectors in upcoming observat…
