Statistical-Uncertainty-Driven Selection of Evaluation Frequency for Time-Dependent Sensing Calibration: A Demonstration with KAGRA Data
Shingo Hido, Takahiro Yamamoto, Dan Chen +2
Accurate calibration of the gravitational-wave strain h(t) is essential for both detection and astrophysical inference. In operating detectors, slow temporal variations in the sens…

Statistical Estimation and Correction of Model-Measurement Bias in Time-Dependent Correction Factors of KAGRA
Shingo Hido, Takahiro Yamamoto, Dan Chen +2
Calibration of gravitational-wave detectors reconstructs the strain h(t) from the detector output, and bias and uncertainty in this reconstruction directly affect downstream analys…

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…
