Accounting for detector calibration uncertainty in black-hole ringdown analysis
Rowina S. Nathan, Shingo Hido, Neil Lu +3
Detector calibration systematics can bias measurements of a remnant black hole's mass and spin, producing spurious evidence against general relativity if unaccounted for. The ringd…

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…
