Hunting for dark halo substructure using submilliarcsecond-scale observations of macrolensed radio jets
Erik Zackrisson, Saghar Asadi, Kaj Wiik +8
Dark halo substructure may reveal itself through secondary, small-scale gravitational lensing effects on light sources that are macrolensed by a foreground galaxy. Here, we explore…
Detection of isolated population III stars with the James Webb Space Telescope
Claes-Erik Rydberg, Erik Zackrisson, Peter Lundqvist +1
The first population III stars are predicted to form in minihalos at a redshift of approximately 10-30. The James Webb Space Telescope (JWST), tentatively scheduled for launch in 2…
Detecting gravitationally lensed population III galaxies with the Hubble Space Telescope and the James Webb Space Telescope
E. Zackrisson, A. Zitrin, M. Trenti +6
Small galaxies consisting entirely of population III (pop III) stars may form at high redshifts, and could constitute one of the best probes of such stars. Here, we explore the pro…
