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 ...

Narrowband Radio Technosignature Search Toward 3I/ATLAS with FAST
The Astrophysical Journal3I/ATLAS is the third confirmed interstellar object passing through the solar system. In this work, we conduct a narrowband radio technosignature search toward 3I/ATLAS using the Five-hundred-meter Aperture Spherical Telescope (FAST) L -band multibeam ...

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 ...

Technosignature Searches of Interstellar Objects
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 discovery of ISOs is quite recent, their utility as targets in the search for technosignatures (historically known as the Search for Extraterrestrial Intelligence -- SETI) has ...

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 ...
