A Tale of Two Calibrators: Comparing Newtonian and Photon Calibration in Advanced LIGO after the Third Observing Run
Dana Jones, Michael P. Ross, Ling Sun +5
Precise calibration of LIGO's strain readout plays a vital role in our ability to extract information from gravitational-wave detections. We present a comparative analysis of two i…
The impact of physically motivated calibration errors on search pipeline detection parameters for broadband burst Signals
Milan Wils, Brad Ratto, Jeffrey S. Kissel +4
Imperfections in the calibration of gravitational wave observatories introduce frequency dependent amplitude and phase errors on the measured GW signal. Previous unmodelled burst s…
Toward Low-Latency, High-Fidelity Calibration of the LIGO Detectors with Enhanced Monitoring Tools
M. Wade, J. Betzwieser, D. Bhattacharjee +8
Accurate and reliable calibration of the Advanced LIGO detectors has enabled a plethora of gravitational-wave discoveries in the detectors' first decade of operation, starting with…
Squeezing the quantum noise of a gravitational-wave detector below the standard quantum limit
Wenxuan Jia, Victoria Xu, Kevin Kuns +168
Precision measurements of space and time, like those made by the detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO), are often confronted with fundamental…
physiCal: A physical approach to the marginalization of LIGO calibration uncertainties
Salvatore Vitale, Carl-Johan Haster, Ling Sun +4
The data from ground based gravitational-wave detectors such as Advanced LIGO and Virgo must be calibrated to convert the digital output of photodetectors into a relative displacem…
Machine-learning non-stationary noise out of gravitational wave detectors
Gabriele Vajente, Yiwen Huang, Maximiliano Isi +4
Signal extraction out of background noise is a common challenge in high precision physics experiments, where the measurement output is often a continuous data stream. To improve th…
