WISE/CatWISE Constraints On Dysonian Waste: A Mid-Infrared Scan for Galaxy-Scale Heat Signatures
Introduction: The Dysonian Search in the Mid-Infrared Dysonian SETI seeks indirect indicators of advanced civilizations by looking for large-scale astroengineering signatures, notably waste heat in the mid-infrared. This study leverages all-sky infrared data from WISE and CatWISE to probe galaxy-scale systems for anomalous, diffuse infrared emission that could signify large-scale energy usage. Starting from the…

WISE/CatWISE Constraints On Dysonian Waste in Galaxy-Scale Searches
Introduction: The Dysonian Approach in Galaxy-Scale Searches Dysonian SETI searches seek techno-signatures in the energy budgets of galaxies, looking for the waste heat from megastructures or advanced civilizational activities. In the mid-infrared (MIR), thermal emission from engineered structures or anomalous energy use could reveal itself as excess radiation relative to starlight. This article discusses how…

WISE/CatWISE Constraints On Dysonian Waste: Probing Galaxy-Scale Heat Signatures in the Mid-IR
Overview In the search for technosignatures, astronomers increasingly turn to Dysonian methods—looking for evidence of galaxy-scale engineering that radiates heat at mid-infrared (MIR) wavelengths. Using data from the Wide-field Infrared Survey Explorer (WISE) and the CatWISE catalog, researchers cross-match large galaxy samples with mid-IR measurements to identify anomalous heat signatures that could indicate megastructures such…
