An arm length stabilization system for KAGRA and future gravitational-wave detectors
T. Akutsu, M. Ando, K. Arai +198
Modern ground-based gravitational wave (GW) detectors require a complex interferometer configuration with multiple coupled optical cavities. Since achieving the resonances of the a…
Reanalysis of the binary neutron star mergers GW170817 and GW190425 using numerical-relativity calibrated waveform models
Tatsuya Narikawa, Nami Uchikata, Kyohei Kawaguchi +4
We reanalyze gravitational waves from binary-neutron-star mergers GW170817 and GW190425 using a numerical-relativity (NR) calibrated waveform model, the TF2+_Kyoto model, which inc…
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…
Searching for black hole echoes from the LIGO-Virgo Catalog GWTC-1
Nami Uchikata, Hiroyuki Nakano, Tatsuya Narikawa +3
We have examined gravitational wave echo signals for nine binary black hole merger events observed by Advanced LIGO and Virgo during the first and second observation runs. To const…
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…
Vibration isolation system with a compact damping system for power recycling mirrors of KAGRA
Y. Akiyama, T. Akutsu, M. Ando +169
A vibration isolation system called Type-Bp system used for power recycling mirrors has been developed for KAGRA, the interferometric gravitational-wave observatory in Japan. A sus…
