Gravitational Wave Detection with Photometric Surveys

Understand

Gravitational wave (GW) detections have enriched our understanding of the universe.

• To date, all single-source GW events were found by interferometer-type detectors.
• We study a detection method using astrometric solutions from photometric surveys and demonstrate that it offers a highly flexible frequency range, uniquely complementing existing detection methods.
• From repeated point-source astrometric measurements, we may extract GW-induced deflections and infer wave parameters.
