Breakthrough Listen's Automated Commensal Technosignature Survey with MeerKAT
Daniel J. Czech, David H. E. MacMahon, Ian Heywood +20
The search for extraterrestrial intelligence (SETI) is an ongoing effort to detect technosignatures, evidence of technologically capable life beyond Earth. Conducting a comprehensi…
A search for narrowband technosignatures from LTT 3780 with the Allen Telescope Array and the Karl G. Jansky Very Large Array
Chenoa D. Tremblay, Sofia Z. Sheikh, Vishal Gajjar +9
The LTT3780 system hosts two known exoplanets-LTT3780b, a rocky super-Earth, and LTT3780c, a temperate sub-Neptune-orbiting a nearby M dwarf on opposite sides of the radius valley.…
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…
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…
SETI@home: Data Acquisition and Front-End Processing
Eric J. Korpela, David P. Anderson, Jeff Cobb +3
SETI@home is a radio Search for Extraterrestrial Intelligence (SETI) project, looking for technosignatures in data recorded at multiple observatories from 1998 to 2020. Most radio…
