Dyson Swarm Archives

Peak emission wavelength of a Dyson Swarm as a function of swarm temperature, following Wien’s displacement law, λmax = b/TDS. The shaded regions indicate the approximate wavelength coverage of key infrared observatories: JWST/NIRCam (red band with star hatching, 0.6−5.0 µm ) JWST/MIRI (orange band with slanted hatching, 5.0−28.3 µm) and Roman/Euclid (NIR) (blue band with dotted hatching, 0.5−2.0 µm). For example, a swarm at TDS ∼ 300 K peaks near ∼ 10 µm, within JWST- MIRI’s sensitivity, whereas hotter swarms (TDS ≳ 1000 K) peak in the near-IR range of Euclid and Roman. -- astro-ph.IM

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).
