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…
Upper Limits on Radio Emission from the K2-18 System
Kelvin Wandia, Chenoa Tremblay, Michael A. Garrett +11
Stellar and planetary magnetic fields play a crucial role in the habitability of a planet and the integrity of its atmosphere. The recently claimed detection of biosignatures, meth…
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…
New Metrics for Identifying Variables and Transients in Large Astronomical Surveys
Shih Ching Fu, Arash Bahramian, Aloke Phatak +5
A key science goal of large sky surveys such as those conducted by the Vera C. Rubin Observatory and precursors to the Square Kilometre Array is the identification of variable and…
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…
