Panoramic SETI: searching for technosignatures and astrophysical transients

Optical SETI (Search for Extraterrestrial Intelligence) instruments exploring the very fast time domain, with large effective collecting areas and large sky coverages, are particularly well-suited for the detection of optical techno-signatures and astrophysical transient sources. The Panoramic SETI experiment (PANOSETI) aims to observe optical transients from nanosecond to second precision across a wide instantaneous field-of-view (~100 sq.deg. per telescope pair) by using two or more assemblies of telescopes to reject spurious signals by coincidence detection. On-sky results from pairs of PANOSETI telescopes deployed at Lick Observatory using baselines <700m are presented to evaluate instrument performance and false alarm rates.
