Model independent constraints on the cosmological expansion rate
Edvard Mortsell, Chris Clarkson
We investigate what current cosmological data tells us about the cosmological expansion rate in a model independent way. Specifically, we study if the expansion was decelerating at…
Prospects and pitfalls of gravitational lensing in large supernova surveys
Jakob Jonsson, Taia Kronborg, Edvard Mortsell +1
To investigate the effect of gravitational lensing of supernovae in large ongoing surveys, we simulate the effect of gravitational lensing magnification on individual supernovae us…
Extinction properties of lensing galaxies
Linda Ostman, Ariel Goobar, Edvard Mortsell
Context. Observations of quasars shining through foreground galaxies, offer a way to probe the dust extinction curves of distant galaxies. Interesting objects for this study are fo…
Supernova Cosmology and the ESSENCE project
Jesper Sollerman, Claudio Aguilera, Andy Becker +27
The proper usage of Type Ia supernovae (SNe Ia) as distance indicators has revolutionized cosmology, and added a new dominant component to the energy density of the Universe, dark…
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…
