Millimetre/Sub-Millimetre SETI: Expanding the Radio Technosignature Parameter Space with ALMA2040
Louisa A. Mason, Michael A. Garrett, Sofia Z. Sheikh +5
The search for extraterrestrial intelligence (SETI) has been largely concentrated at centimetre wavelengths, and in particular in the 'water hole' (1.42-1.66 GHz) range. The millim…
Opportunity Lost in Searching for Technosignatures
Steve Prabu, David DeBoer, Andrew Siemion +6
The sensitivity of radio technosignature searches has improved dramatically over the last five decades; however, as the RFI environment from which these searches are conducted has…

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.…
Archival Diagnostics for Potential Background Contaminantsof Project Hephaistos Dyson Sphere Candidates
Tongtian Ren, Michael A. Garrett, Erik Zackrisson +4
We report on the diagnostic investigation of nine Project Hephaistos Dyson Sphere candidate M-dwarfs based on archival data. By comparing the Gaia DR3 positions with epoch 2016.0,…
Searching for Extraterrestrial Intelligence with the SKA
Chenoa D. Tremblay, Alex Andersson, Joe Bright +19
The search for technosignatures (also known as the Search for Extraterrestrial Intelligence or SETI) depends critically on our ability to distinguish artificial signals from the ri…
On the Deepest Search for Galactic Center Pulsars and an Examination of an Intriguing Millisecond Pulsar Candidate
Karen I. Perez, Vishal Gajjar, Slavko Bogdanov +6
We report results of one of the most sensitive pulsar surveys to date targeting the innermost region of the Galactic Center (GC) using the Robert C. Byrd Green Bank Telescope (GBT)…
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…
Technosignature Searches of Interstellar Objects
James R. A. Davenport, Sofia Z. Sheikh, Steve Croft +17
With the discovery of the third confirmed interstellar object (ISO), 3I/ATLAS, we have entered a new phase in the exploration of these long-predicted objects. Though confirmed disc…
Radio Emission from a Nearby M dwarf Binary
Kelvin Wandia, Michael A. Garrett, Robert J. Beswick +7
We present the detection of the binary system 2MASS J02132062+3648506 AB using the Karl G. Jansky Very Large Array (VLA) archive data observed at 4-8 GHz. The system is a triple co…
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…
MeerKAT observations of Procyon at 815.5 MHz
Ian Heywood, Andrew P. V. Siemion, Daniel Czech +5
We have conducted observations of the nearby (11.46 ly) star system Procyon, using MeerKAT's UHF (544-1087 MHz) receivers. We produce full-Stokes time and frequency integrated cont…
