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…
