Distance‐Redshift in Inhomogeneous Ω<sub>0</sub> = 1 Friedmann‐Lemaitre‐Robertson‐Walker Cosmology
Distance-redshift relations are given in terms of associated Legendre functions for partially filled beam observations in spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) cosmologies. These models are dynamically pressure-free and flat FLRW on large scales but, because of mass inhomogeneities, differ in their optical properties. The partially filled beam area-redshift equation is a …
