Average luminosity distance in inhomogeneous universes

Valentin Kostov

Using numerical ray tracing, the paper studies how the average distance modulus in an inhomogeneous universe differs from its homogeneous counterpart. The averaging is over all dir…

Average luminosity distance in inhomogeneous universes

Valentin Kostov

The paper studies the correction to the distance modulus induced by inhomogeneities and averaged over all directions from a given observer. The inhomogeneities are modeled as mass-…
