Mitigating effects of nonlinearities in homodyne quadrature interferometers
Johannes Lehmann, Artem Basalaev, Jonathan J. Carter +12
Homodyne Quadrature interferometers (HoQI) are an interferometric displacement sensing scheme proven to have excellent noise performance, making them a strong candidate for sensing…
Decadal upgrade strategy for KAGRA toward post-O5 gravitational-wave astronomy
KAGRA Collaboration, T. Akutsu, M. Ando +150
The KAGRA Collaboration has investigated a ten-year upgrade strategy for the KAGRA gravitational wave detector, considering a total of 14 upgrade options that vary in mirror mass,…
Identification of Noise-Associated Glitches in KAGRA O3GK with Hveto
T. Akutsu, M. Ando, M. Aoumi +148
Transient noise ("glitches") in gravitational wave detectors can mimic or obscure true signals, significantly reducing detection sensitivity. Identifying and excluding glitch-conta…
Testing Compact, Fused Silica Resonator Based Inertial Sensors in a Gravitational Wave Detector Prototype Facility
J J Carter, P Birckigt, J Lehmann +15
Future gravitational wave observatories require significant advances in all aspects of their seismic isolation; inertial sensors being a pressing example. Inertial sensors using gr…
Input optics systems of the KAGRA detector during O3GK
T. Akutsu, M. Ando, K. Arai +246
KAGRA, the underground and cryogenic gravitational-wave detector, was operated for its solo observation from February 25th to March 10th, 2020, and its first joint observation with…
Wavefront Sensing with a Coupled Cavity for Torsion-Bar Antenna
Yuka Oshima, Satoru Takano, Ching Pin Ooi +2
Torsion-Bar Antenna (TOBA) is a ground-based gravitational wave detector using torsion pendulums. TOBA can detect intermediate-mass black hole binary mergers, gravitational wave st…
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…
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…
