Microlensing Signatures Of Dyson Sphere-like Structures Around Primordial Black Holes As Technosignatures Of Extraterrestrial Advanced Civilizations
We investigate the microlensing detectability of extraterrestrial technosignatures originating from Dyson sphere – like structures, such as Dyson Swarms surrounding primordial black holes (PBHs).
