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…
Measurements of tropospheric ice clouds with a ground-based CMB polarization experiment, POLARBEAR
Satoru Takakura, Mario A. O. Aguilar-Faúndez, Yoshiki Akiba +45
The polarization of the atmosphere has been a long-standing concern for ground-based experiments targeting cosmic microwave background (CMB) polarization. Ice crystals in upper tro…
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…
CHRONOS: Cryogenic sub-Hz cROss torsion bar detector with quantum NOn-demolition Speed meter
Yuki Inoue, Hsiang-Chieh Hsu, Hsiang-Yu Huang +7
We propose a next-generation ground-based gravitational-wave detector, Cryogenic sub-Hz cROss torsion-bar detector with quantum NOn-demolition Speed meter (CHRONOS), optimized for…
High-precision temperature monitoring system for room-temperature equipment in astrophysical observations
Daiki Tanabe, Masaya Hasegawa, Masashi Hazumi +5
We present a precise thermometry system to monitor room-temperature components of a telescope for radio-astronomy such as cosmic microwave background (CMB) observation. The system…
