WISE/CatWISE Constraints On Dysonian Waste-Heat Technosignatures In Nearby Galaxies
We search for galaxy-scale (Dysonian) waste heat in the mid-infrared using WISE. Starting from the 2MASS Redshift Survey (2MRS), we cross-match to CatWISE2020 and AllWISE, apply standard MIR AGN/starburst vetoes […]
