We report on a search for engineered signals from a sample of 692 nearby stars using the Robert C. Byrd Green Bank Telescope, undertaken as part of the $Breakthrough~Listen~Initiative$ search for extraterrestrial intelligence. Observations were made over 1.1$-$1.9 GHz (L band), with three sets of five-minute observations of the 692 primary targets, interspersed with five-minute observations of secondary targets. By comparing the "ON" and "OFF" observations we are able to identify terrestrial… Expand

Bayesian approach to SETI
TLDR
A Bayesian formulation of SETI is constructed to infer the posterior probability of the mean number of radio signals crossing Earth, given a positive or a null outcome of all-sky searches for nonnatural radio emissions, from the current state of ignorance about the galactic population of nonnatural electromagnetic signals.

TLDR
The Search for Extraterrestrial Intelligence (SETI) attempts to address the possibility of the presence of technological civilizations beyond the Earth by identifying and removing four kinds of radio frequency interference (RFI) and ranks interesting narrow band candidate ET signals. Expand
