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…
Micron-Scale Technosignatures: How a Cubic Metre of Lunar Regolith May Begin to Constrain the Number of Past Technological Civilisations in the Galaxy
Lewis J. Pinault, Brian C. Lacki, Ian A. Crawford +1
Building on Arkhipov's proposal that technogenic artefacts may survive natural interstellar transport and accumulate on Solar System surfaces, we examine the prospects for identify…
Dust to Dust: Prospects for Passive Technosignatures as Relics of ETI
Brian C. Lacki
Technological societies are separated in time, not just space -- that is the lesson of the Drake equation. Might the best way to seek them be to find technosignatures that persist…
Shadows of Giants: Constraints on Stupendously Large Black Holes from Negative Sources against the Cosmic Microwave Background
Brian C. Lacki
Stupendously large astrophysical black holes (SLABs) are hypothetical black holes with masses of more than a trillion Suns. Because observable consequences of their existence have…
Artificial Broadcasts as Galactic Populations: III. Constraints on Radio Broadcasts from the Cosmic Population of Inhabited Galaxies
Brian C. Lacki
Any population of artificial radio broadcasts in a galaxy contributes to its integrated radio luminosity. If this radio emission is bright enough, inhabited galaxies themselves for…
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…
