Novel Algorithmic and Astrophysical Methods in the Search for Radio Technosignatures [PDF]
Over the 60 years since the first published search for radio technosignatures, relatively established methods have come about for the detection and analysis of narrowband radio signals in the Search for Extraterrestrial Intelligence (SETI).

Natural-Like Technosignatures and Artificial Intelligence
, 2023 Natural-like technosignatures candidates may represent a detection problem for both artificial systems and humans. We tested traditional computer vision models with natural formations with special characteristics, Ahuna Mons region in Ceres in this particular case. We looked if these artificial models may represent a trustful aid to human detection and

A Model-independent Radio Telescope Dark Matter Search in the L and S Bands
The Astrophysical Journal LettersUltralight bosonic dark matter in its most general form can be detected through its decay or annihilation to a quasimonochromatic radio line. Assuming only that this line is consistent with the most general properties of the expected phase space of our ...

Anticipation in the Search for Technosignatures: a viewpoint
, 2020 The concept of “technosignatures” has been defined within the encompassing endeavor of searching for life beyond Earth as “evidence of some technology that modifies its environment in ways that are detectable”. This poster proposes the application of insights from the study of anticipation to the Search for Technosignatures, in order to proactively ...

Ground to Dust: Collisional Cascades and the Fate of Kardashev II Megaswarms
The Astrophysical JournalExtraterrestrial intelligences are speculated to surround stars with structures to collect their energy or to signal distant observers. If they exist, these most likely are megaswarms, vast constellations of satellites (elements) in orbit around the ...
