The case for gravitational millilensing in the multiply--imaged quasar B1152+199
Saghar Asadi, Erik Zackrisson, Eskil Varenius +3
Previous Very Long Baseline Interferometry (VLBI) observations of the quasar B1152+199 at 5GHz has revealed two images of a strongly lensed jet with seemingly discordant morphologi…
Probing cold dark matter subhalos with simulated ALMA observations of macrolensed sub-mm galaxies
Saghar Asadi, Erik Zackrisson, Emily Freeland
If the dark matter halos of galaxies contain large numbers of subhalos as predicted by the CDM model, these subhalos are expected to appear in strong galaxy--galaxy lens systems…
Extragalactic SETI: The Tully-Fisher relation as a probe of Dysonian astroengineering in disk galaxies
E. Zackrisson, P. Calissendorff, S. Asadi +1
If advanced extraterrestrial civilizations choose to construct vast numbers of Dyson spheres to harvest radiation energy, this could affect the characteristics of their host galaxi…
A search for Population III galaxies in CLASH. I. Singly-imaged candidates at high redshift
Claes-Erik Rydberg, Erik Zackrisson, Adi Zitrin +6
Population III galaxies are predicted to exist at high redshifts and may be rendered sufficiently bright for detection with current telescopes when gravitationally lensed by a fore…
