Inhomogeneities and the Intergalactic Distance-Redshift Relation

Astrophysics 2007-05-23 v1

Abstract

Modifications in Friedmann-Lemaitre-Robertson-Walker (FLRW) Hubble diagrams caused by mass density inhomogeneities are used to illustrate possible effects on a determination of the mass parameter Ωm\Omega_m and the cosmological constant Λ\Lambda. The values of these parameters inferred from a given set of observations depend on the fractional amount of matter in inhomogeneities and can differ from those obtained by using standard FLRW Hubble diagrams by as much as a factor of two.
