SILVIA: Ultra-precision formation flying demonstration for space-based interferometry
Takahiro Ito, Kiwamu Izumi, Isao Kawano +26
We propose SILVIA (Space Interferometer Laboratory Voyaging towards Innovative Applications), a mission concept designed to demonstrate ultra-precision formation flying between thr…
Cross-Correlated Force Measurement for Thermal Noise Reduction in Torsion Pendulum
Yusuke Okuma, Kiwamu Izumi, Kentaro Komori +1
The torsion pendulum is a prevailing instrument for measuring small forces acting on a solid body or those between solid bodies. While it offers powerful advantages, the measuremen…
Demonstration of an amplitude filter cavity at gravitational-wave frequencies
Kentaro Komori, Dhruva Ganapathy, Chris Whittle +4
Quantum vacuum fluctuations fundamentally limit the precision of optical measurements, such as those in gravitational-wave detectors. Injection of conventional squeezed vacuum can…
Optimal detuning for quantum filter cavities
Chris Whittle, Kentaro Komori, Dhruva Ganapathy +4
Vacuum quantum fluctuations impose a fundamental limit on the sensitivity of gravitational-wave interferometers, which rank among the most sensitive precision measurement devices e…
Compact integrated optical sensors and electromagnetic actuators for vibration isolation systems in the gravitational-wave detector KAGRA
Tomotada Akutsu, Fabián Erasmo Peña Arellano, Ayaka Shoda +18
This paper reports on the design and characteristics of a compact module integrating an optical displacement sensor and an electromagnetic actuator for use with vibration-isolation…
Frequency-Dependent Squeezing for Advanced LIGO
L. McCuller, C. Whittle, D. Ganapathy +13
The first detection of gravitational waves by the Laser Interferometer Gravitational-wave Observatory (LIGO) in 2015 launched the era of gravitational wave astronomy. The quest for…
A Cryogenic Silicon Interferometer for Gravitational-wave Detection
Rana X Adhikari, Odylio Aguiar, Koji Arai +108
The detection of gravitational waves from compact binary mergers by LIGO has opened the era of gravitational wave astronomy, revealing a previously hidden side of the cosmos. To ma…
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…
