Multibeam SETI Observations Toward Nearby M Dwarfs with FAST

The 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.

Optical SETI Observations of the Anomalous Star KIC 8462852

, 2015
To explore the hypothesis that KIC 8462852's aperiodic dimming is caused by artificial megastructures in orbit (Wright et al. 2015), rather than a natural cause such as cometary fragments in a highly elliptical orbit (Marengo et al.

Bayesian approach to SETI

, 2018
The search for technosignatures from hypothetical galactic civilizations is going through a new phase of intense activity. For the first time, a significant fraction of the vast search space is expected to be sampled in the foreseeable future ...

The FAST-SETI Milky Way Globular Cluster Survey. I. A Pilot Multibeam On-the-fly Search of Five Globular Clusters at the L Band

The Astronomical Journal
We report a narrowband technosignature search toward five Milky Way globular clusters—NGC 6171, NGC 6218, NGC 6254, NGC 6838, and IC 1276—using Five-hundred-meter Aperture Spherical radio Telescope (FAST)’s 19 beam L -band receiver (1.05–1.45 GHz).

WISE/CatWISE Constraints on Dysonian Waste-heat Technosignatures in Nearby Galaxies

The Astronomical Journal
We search for galaxy-scale (Dysonian) waste heat in the mid-infrared using WISE. Starting from the 2MASS Redshift Survey, we crossmatch to CatWISE2020 and AllWISE, apply standard MIR AGN/starburst vetoes (Stern, Assef R90, Jarrett), and treat W1 and W2 ...

Microlensing Signatures of Dyson Sphere–like Structures around Primordial Black Holes as Technosignatures of Extraterrestrial Advanced Civilizations

The Astrophysical Journal
We investigate the microlensing detectability of extraterrestrial technosignatures originating from Dyson sphere-like structures, such as Dyson swarms surrounding primordial black holes.
