Noise reduction in suspension control with photon-pressure actuator for CHRONOS gravitational wave detector
Daiki Tanabe, Yuki Inoue, Mario Juvenal S. Onglao
Improving sub-Hz sensitivity of gravitational wave (GW) detectors is important to detect heavier binary black hole mergers and study phenomena in stronger gravity fields. Torsion-b…
Improving calibration accuracy with torque coupled gravity field calibrator for sub-Hz gravitational wave observation in CHRONOS
Yuki Inoue, Daiki Tanabe, Vivek Kumar
A fundamental challenge in low-frequency gravitational-wave detectors is the limited signal-to-noise ratio (SNR) of calibration lines, particularly in torsion-bar systems where the…
Cryogenic sub-Hz cROss torsion bar detector with quantum NOn-demolition Speed meter (CHRONOS) for gravitational wave detection
Yuki Inoue, Daiki Tanabe, M. Afif Ismail +3
We present the optical design and sensitivity modeling of the Cryogenic sub-Hz cROss torsion-bar detector with quantum NOn-demolition Speed meter (CHRONOS), a triangular Sagnac spe…
Prospects for Observing Gravity-gradient Noise and Earthquake Gravity Signals with CHRONOS
Mario Juvenal S. Onglao, Yuki Inoue, Daiki Tanabe
Ground-based gravitational-wave detectors operating in the sub-Hertz regime are expected to be strongly limited by environmental gravity-gradient fluctuations, commonly referred to…
Noise budget of Cryogenic sub-Hz cROss torsion bar detector with quantum NOn-demolition Speed meter (CHRONOS)
Mario Juvenal S. Onglao, Hsiang-Yu Huang, Yuki Inoue +2
CHRONOS is a proposed gravitational-wave detector designed to operate in the sub-Hz frequency range (0.1 to 10 Hz), a largely unexplored band due to strong noise sources that hampe…
Probing Yukawa Gravity with Modulated Newtonian Cancellation in the CHRONOS Detector
Yuki Inoue, Hsiang-Yu Huang, Vivek Kumar +1
We investigate the sensitivity of a torsion-bar gravitational-wave detector to Yukawa-type deviations from Newtonian gravity using a differential gravitational calibrator (GCal), w…
