The Dyer-Roeder distance-redshift relation in inhomogeneous universes
E. Mortsell
Using Monte-Carlo methods, we determine the best-fit value of the homogeneity parameter alpha in the Dyer-Roeder distance-redshift relation for a variety of redshifts, inhomogeneit…

Determining the fraction of compact objects in the Universe using supernova observations
E. Moertsell, A. Goobar, L. Bergstrom
We investigate the possibility to determine the fraction of compact objects in the Universe by studying gravitational lensing effects on Type Ia supernova observations. Using simul…
