A Polarization-Decomposed Method for Simulating Inhomogeneous Birefringence in Laser-Interferometric Gravitational-Wave Detectors
Haoyu Wang, Yuta Michimura, Keiko Kokeyama +9
Birefringence in test mass substrates is an emerging limitation for current and future laser-interferometric gravitational-wave detectors, particularly as detectors move toward hig…
Proof-of-principle demonstration of a Polarization-Circulation Speed Meter
Yohei Nishino, Tomotada Akutsu, Yoichi Aso +3
We present the first experimental implementation of a polarization-circulation speed meter. In our experiment, the interferometer was reduced to a single-cavity configuration with…
GW241011 and GW241110: Exploring Binary Formation and Fundamental Physics with Asymmetric, High-Spin Black Hole Coalescence
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1783
We report the observation of gravitational waves from two binary black hole coalescences during the fourth observing run of the LIGO--Virgo--KAGRA detector network, GW241011 and GW…
Theoretical Characteristics of a three-point Roberts Linkage
Munetake Otsuka, Kohei Mitsuhashi, Ryutaro Takahashi +3
The Roberts linkage is recognized for enabling long-period pendulum motion in a compact format. Utilizing this characteristic, we are developing a three-point Roberts linkage for v…
Optimizing Active Seismic Isolation Systems in Gravitational-Wave Detectors
Terrence Tsang, Fabián Erasmo Peña Arellano, Takafumi Ushiba +3
Gravitational wave detectors such as KAGRA, a 3-km long underground laser interferometer in Japan, require elaborate passive and active seismic isolation of their mirrors. With the…
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…
Length sensing and control strategies for the LCGT interferometer
Yoichi Aso, Kentaro Somiya, Osamu Miyakawa
The optical readout scheme for the length degrees of freedom of the LCGT interferometer is proposed. The control scheme is compatible both with the broadband and detuned operations…
