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…
KAGRA: 2.5 Generation Interferometric Gravitational Wave Detector
T. Akutsu, M. Ando, K. Arai +188
The recent detections of gravitational waves (GWs) reported by LIGO/Virgo collaborations have made significant impact on physics and astronomy. A global network of GW detectors wil…
Construction of KAGRA: an Underground Gravitational Wave Observatory
T. Akutsu, M. Ando, S. Araki +222
Major construction and initial-phase operation of a second-generation gravitational-wave detector KAGRA has been completed. The entire 3-km detector is installed underground in a m…
The status of KAGRA underground cryogenic gravitational wave telescope
KAGRA Collaboration, T. Akutsu, M. Ando +146
KAGRA is a 3-km interferometric gravitational wave telescope located in the Kamioka mine in Japan. It is the first km-class gravitational wave telescope constructed underground to…
Estimation of starting times of quasinormal modes in ringdown gravitational waves with the Hilbert-Huang transform
Kazuki Sakai, Ken-ichi Oohara, Hiroyuki Nakano +2
It is known that a quasinormal mode (QNM) of a remnant black hole dominates a ringdown gravitational wave (GW) in a binary black hole (BBH) merger. To study properties of the QNMs,…
Optimal follow-up observations of gravitational wave events with small optical telescopes
Tatsuya Narikawa, Masato Kaneyama, Hideyuki Tagoshi
We discuss optimal strategy for follow-up observations by 1-3 m class optical/infrared telescopes which target optical/infrared counterparts of gravitational wave events detected w…
Amplitude-based detection method for gravitational wave bursts with the Hilbert-Huang Transform
Kazuki Sakai, Ken-ichi Oohara, Masato Kaneyama +1
We propose a new detection method for gravitational wave bursts. It analyzes observed data with the Hilbert-Huang transform, which is an approach of time-frequency analysis constru…
On Investigating EMD Parameters to Search for Gravitational Waves
Hirotaka Takahashi, Ken-ichi Oohara, Masato Kaneyama +2
The Hilbert-Huang transform (HHT) is a novel, adaptive approach to time series analysis. It does not impose a basis set on the data or otherwise make assumptions about the data for…
Prospects for Observing and Localizing Gravitational-Wave Transients with Advanced LIGO, Advanced Virgo and KAGRA
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1319
We present our current best estimate of the plausible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next several years,…
