Nonlinear Independent Component Analysis Scheme and its application to gravitational wave data analysis
Jun'ya Kume, Koh Ueno, Tatsuki Washimi +3
Noise subtraction is a crucial process in gravitational wave (GW) data analysis to improve the sensitivity of interferometric detectors. While linear noise coupling has been extens…
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…
TOrsion-Bar Antenna: A Ground-Based Detector for Low-Frequency Gravity Gradient Measurement
Satoru Takano, Tomofumi Shimoda, Yuka Oshima +12
The Torsion-Bar Antenna (TOBA) is a torsion pendulum-based gravitational detector developed to observe gravitational waves in frequencies between 1 mHz and 10 Hz. The low resonant…
Evaluation of microseismic motion at the KAGRA site based on ocean wave data
S. Hoshino, Y. Fujikawa, M. Ohkawa +2
The microseismic motion, ambient ground vibration caused by ocean waves, affects ground-based gravitational wave detectors. In this study, characteristics of the ocean waves includ…
