Analysis of Kepler mission data suggests that the Milky Way includes billions of Earth-like planets in the habitable zone of their host star. Current technology enables the detection of technosignatures emitted from a large fraction of the Galaxy. We describe a search for technosignatures that is sensitive to Arecibo-class transmitters located within ~420 ly of Earth and transmitters that are 1000 times more effective than Arecibo within ~13 000 ly of Earth. Our observations focused on 14… Expand

The Breakthrough Listen Search for Intelligent Life: Public Data, Formats, Reduction, and Archiving
TLDR
The hardware and software pipeline used for collection, reduction, archival, and public dissemination of Listen data is described, the data formats and tools are described, andBLDR 1.0 is presented, a defined set of publicly-available raw and reduced data totalling 1 PB. Expand
A Machine-Learning-Based Direction-of-Origin Filter for the Identification of Radio Frequency Interference in the Search for Technosignatures
TLDR
This work designed and trained a CNN that can determine whether or not a signal detected in one scan is also present in another scan, and it is found that the CNN reduces the number of signals requiring visual inspection after the application of traditional DoO filters by a factor of 6–16 in nominal situations.

Exo-Astrosociology and the Search for Technosignatures
The search for extraterrestrial societies on exoplanets, exomoons, and artificial structures has thus far proven unsuccessful. Nevertheless, astrosociology focuses on the human dimension of spaceExpand
The radio search for technosignatures in the decade 2020-2030
TLDR
A modest budgetary increment can expand the search for life in the universe from primitive to complex life and from the solar neighborhood to the entire Galaxy. Expand
A Search for Technosignatures around 31 Sun-like Stars with the Green Bank Telescope at 1.15–1.73 GHz
TLDR
An improved candidate signal detection procedure that relies on the topographic prominence of the signal power, which nearly doubles the signal detection count of some previously analyzed data sets is applied, as well as improvements to the data processing pipeline. Expand
