This three-year, $365,233 Project Grant from the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) supports research in gravitational wave signal reconstruction and advanced noise modeling at Montana State University. The award goals are to significantly improve gravitational wave signal processing speed to analyze the increasing volume of detections from LIGO and Virgo; develop new tools to detect and characterize unmodeled or poorly understood exotic signals, including deviations from general relativity; and deploy advanced noise modeling techniques to account for non-stationary and non-Gaussian instrument noise, such as glitches. The research is expected to develop signal reconstruction methods that can jointly infer gravitational wave signals, noise transients, and non-stationary noise floor drifts in minutes versus days or weeks for prior analyses. A new low-latency glitch removal algorithm will also be implemented to safely clean LIGO-Virgo data in real time, important for analyzing longer signals prone to noise encounters.
