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.…
A Narrowband Technosignature Search Toward the Hycean Candidate K2-18b Using the VLA and MeerKAT
C. D. Tremblay, S. Chaudhary, Megan G. Li +12
K2-18b, a sub-Neptune exoplanet located in the habitable zone of its host star, has emerged as an important target for atmospheric characterization and assessments of potential hab…
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…
The First High Frequency Technosignature Search Survey with the Sardinia Radio Telescope
Lorenzo Manunza, Alice Vendrame, Luca Pizzuto +30
The quest for radio signals from technologically-advanced extraterrestrial intelligence has traditionally concentrated on the vicinity of 1.4 GHz. In this paper, we extend the sear…
