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.

A Narrowband Technosignature Search toward the Hycean Candidate K2-18 b Using the VLA and MeerKAT

The Astronomical Journal
K2-18 b, a sub-Neptune exoplanet located in the habitable zone of its host star, has emerged as an important target for atmospheric characterization, and assessments of potential habitability.

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

The 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.

In Search of Extraterrestrial Artificial Intelligence Through Dyson Sphere–like Structures around Primordial Black Holes

The Astrophysical Journal
Are we alone? It is a compelling question that human beings have confronted for centuries. The search for extraterrestrial life is a broad range of quests for finding simple forms of life up to intelligent beings in the Universe. The plausible assumption

CARGOISM AND SCIENTIFIC JUSTIFICATION IN THE SEARCH FOR EXTRATERRESTRIAL INTELLIGENCE

Zygon, 2019
This article compares justifications of the search for extraterrestrial intelligence (SETI) presented by scientists with ideational constructs associated with cargo cults in Melanesia. In focusing on similarities between cargoism and SETI, I argue that,
