Lensing magnification of supernovae in the GOODS-fields
Jakob Jonsson, Tomas Dahlen, Ariel Goobar +3
Gravitational lensing of high-redshift supernovae is potentially an important source of uncertainty when deriving cosmological parameters from the measured brightness of Type Ia su…

Corrections for gravitational lensing of supernovae: better than average?
Christofer Gunnarsson, Tomas Dahlen, Ariel Goobar +2
We investigate the possibility of correcting for the magnification due to gravitational lensing of standard candle sources, such as Type Ia supernovae. Our method uses the observed…
