Breakthrough Listen Observations of 3I/ATLAS with the Green Bank Telescope at 1-12 GHz
Ben Jacobson-Bell, Steve Croft, Ellie White +3
3I/ATLAS, an interstellar object, made its closest approach to Earth on 2025 December 19. On 2025 December 18, the Breakthrough Listen program conducted a technosignature search to…
Using anomaly detection to search for technosignatures in Breakthrough Listen observations
Snir Pardo, Dovi Poznanski, Steve Croft +2
We implement a machine learning algorithm to search for extra-terrestrial technosignatures in radio observations of several hundred nearby stars, obtained with the Parkes and Green…
A Novel Technosignature Search in the Breakthrough Listen Green Bank Telescope Archive
Caleb Painter, Steve Croft, Matthew Lebofsky +5
The Breakthrough Listen program is, to date, the most extensive search for technological life beyond Earth. As part of this goal, over the past nine years it has surveyed thousands…
Anomaly Detection and Radio-frequency Interference Classification with Unsupervised Learning in Narrowband Radio Technosignature Searches
Ben Jacobson-Bell, Steve Croft, Carmen Choza +7
The search for radio technosignatures is an anomaly detection problem: Candidate signals represent needles of interest in the proverbial haystack of radio-frequency interference (R…
