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…
Near-IR search for lensed supernovae behind galaxy clusters: III. Implications for cluster modeling and cosmology
Teresa Riehm, Edvard Mörtsell, Ariel Goobar +6
Massive galaxy clusters at intermediate redshifts act as gravitational lenses that can magnify supernovae (SNe) occurring in background galaxies. We assess the possibility to use l…
A model independent measure of the large scale curvature of the Universe
Edvard Mortsell, Jakob Jonsson
Cosmological distances as a function of redshift depend on the effective curvature density via the effect on the geometrical path of photons from large scale spatial curvature and…
Constraining dark matter halo properties using lensed SNLS supernovae
J. Jonsson, M. Sullivan, I. Hook +7
This paper exploits the gravitational magnification of SNe Ia to measure properties of dark matter haloes. The magnification of individual SNe Ia can be computed using observed pro…
Gravitational lensing in the Supernova Legacy Survey (SNLS)
T. Kronborg, D. Hardin, J. Guy +18
The observed brightness of Type Ia supernovae is affected by gravitational lensing caused by the mass distribution along the line of sight, which introduces an additional dispersio…
Weighing dark matter haloes with gravitationally lensed supernovae
Jakob Jonsson, Tomas Dahlen, Isobel Hook +2
High redshift Type Ia supernovae (SNe Ia) are likely to be gravitationally lensed by dark matter haloes of galaxies in the foreground. Since SNe Ia have very small dispersion after…
