Abstract
A procedure for computing distance–redshift statistics in inhomogeneous universes is described. We interpret the generalized Dyer–Roeder equation [Dyer, C. C.; Roeder, R. C. The distance-redshift relation for universes with no intergalactic medium. Astrophys. J. 1972, 174, L115–L117; Dyer, C. C.; Roeder, R. C. Distance-redshift relations for universes with some intergalactic medium. Astrophys. J. 1972, 180, L31–L34] as a stochastic differential equation which treats the shearing forces as Brownian movement and yields a Monte-Carlo procedure. Shear distributions taken from N-body simulations produce a redshift dependent diffusion coefficient Show more
