Are the red halos of galaxies made of low-mass stars? Constraints from subdwarf star counts in the Milky Way halo
E. Zackrisson, C. Flynn
Surface photometry detections of red and exceedingly faint halos around galaxies have resurrected the old question of whether some non-negligible fraction of the missing baryons of…
Strong lensing by subhalos in the dwarf-galaxy mass range I: Image separations
E. Zackrisson, T. Riehm, O. Moeller +2
The cold dark matter scenario predicts that a large number of dark subhalos should be located within the halo of each Milky-way sized galaxy. One tell-tale signature of such dark s…
Constraining the mass of the GRB 030329 progenitor
G. Ostlin, E. Zackrisson, J. Sollerman +2
The long-duration gamma-ray burst (GRB) 030329, associated with supernova (SN) 2003dh, occurred inside a star-forming dwarf galaxy at redshift . The low redshift, and a r…
The impact of nebular emission on the broadband fluxes of high-redshift galaxies
E. Zackrisson, N. Bergvall, E. Leitet
A substantial fraction of the light emitted from young or star-forming galaxies at ultraviolet to near-infrared wavelengths comes from the ionized interstellar medium in the form o…
Dark matter millilensing and VSOP-2
Kaj Wiik, Erik Zackrisson, Teresa Riehm
According to the cold dark matter scenario, a large number of dark subhalos should be located within the halo of each Milky-way sized galaxy. One promising possibility for detectin…
