Demography of galactic technosignatures [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Probabilistic arguments about the existence of technological life beyond Earth traditionally refer to the Drake equation to draw possible estimates of the number of technologically advanced civilizations releasing, either intentionally or not, electromagnetic emissions in the Milky Way.

A Search for Extraterrestrial Technosignatures in Archival FAST Survey Data Using a New Procedure
The Astronomical Journal, 2023 The search for extraterrestrial intelligence (SETI) commensal surveys aim to scan the sky to find possible technosignatures from an extraterrestrial intelligence (ETI). The mitigation of radio frequency interference (RFI) is an important step, especially
