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…
