Cryogenic suspension design for a kilometer-scale gravitational-wave detector
Takafumi Ushiba, Tomotada Akutsu, Yoichi Aso +43
We report the mirror suspension design for Large-scale Cryogenic Gravitational wave Telescope, KAGRA, during bKAGRA Phase 1. Mirror thermal noise is one of the fundamental noises f…
Overview of KAGRA : KAGRA science
KAGRA Collaboration, T. Akutsu, M. Ando +240
KAGRA is a newly build gravitational-wave observatory, a laser interferometer with 3 km arm length, located in Kamioka, Gifu, Japan. In this paper in the series of KAGRA-featured a…
Prospects for improving the sensitivity of the cryogenic gravitational wave detector KAGRA
Yuta Michimura, Kentaro Komori, Yutaro Enomoto +18
Upgrades to improve the sensitivity of gravitational wave detectors enable more frequent detections and more precise source parameter estimation. Unlike other advanced interferomet…
Current status of space gravitational wave antenna DECIGO and B-DECIGO
Seiji Kawamura, Masaki Ando, Naoki Seto +84
Deci-hertz Interferometer Gravitational Wave Observatory (DECIGO) is the future Japanese space mission with a frequency band of 0.1 Hz to 10 Hz. DECIGO aims at the detection of pri…
Estimation of losses in a 300 m filter cavity and quantum noise reduction in the KAGRA gravitational-wave detector
Eleonora Capocasa, Matteo Barsuglia, Jérôme Degallaix +7
The sensitivity of the gravitational-wave detector KAGRA, presently under construction, will be limited by quantum noise in a large fraction of its spectrum. The most promising tec…
