A Model-independent Radio Telescope Dark Matter Search in the L and S Bands

open access: yesThe Astrophysical Journal Letters
Ultralight 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 ...

Multibeam SETI Observations Toward Nearby M Dwarfs with FAST

open access: yesThe Astronomical Journal
The search for extraterrestrial intelligence (SETI) targeted searches aim to observe specific areas and objects to find possible technosignatures. Many SETI researches have focused on nearby stars and their planets in recent years.

Ground to Dust: Collisional Cascades and the Fate of Kardashev II Megaswarms

open access: yesThe Astrophysical Journal
Extraterrestrial 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 ...

Dual-backend Multibeam Position-switching Targeted SETI Observations toward Nearby Active Planet-hosting Systems with FAST

open access: yesThe Astronomical Journal
The Five-hundred-meter Aperture Spherical Telescope (FAST), the world’s largest single-dish radio telescope, lists the search for extraterrestrial intelligence (SETI) as one of its key scientific objectives.
