Accelerating expansion in the swisscheese model

Published 24 Feb 2010 in astro-ph.CO and gr-qc | (1002.4610v2)

Abstract: A version of the Swiss-cheese model is investigated. The flat Friedmann-Robertson-Walker (FRW) universe is modified by the addition of several spherical regions with Lemaitre-Tolman-Bondi metric. We discuss light propagation in this model in detail to pave the way for a detailed numerical study of the Hubble diagram.
