Project Hephaistos -- III. Characterizing anomalous infrared sources identified as Dyson-sphere candidates
Andreas J. Korn, Matías Suazo, Erik Zackrisson +3
The infrared-flux excess of stars harbouring Dyson spheres represent one potential technosignature of extraterrestrial intelligence. In a previous Project Hephaistos paper, we high…
Project Hephaistos -- IV. James Webb Space Telescope Observations of Two Dyson Sphere Candidates
Erik Zackrisson, Arjan Bik, Anita Ali Asgar +11
We report on JWST/MIRI imaging and spectroscopy of two M-dwarf stars previously singled out by project Hephaistos as potential Dyson-sphere candidates (their candidates D and E) du…
Mirror images of lensed star clusters with mismatched spectral energy distributions: A possible signature of top-heavy stellar initial mass functions and extreme stars in high-redshift star clusters
Erik Zackrisson, Jose M. Diego, Jose M. Palencia +4
Strongly lensed star clusters have recently been detected up to redshift in galaxy cluster fields using the James Webb Space Telescope (JWST). When pairs of mirror im…
