- Description
- We derive the exact expression of the angular size-distance redshift relation for a flat Friedmann-Robertson-Walker universe with a cosmological constant, depending on the parameters $\Omega_{\Lambda}$ and $\Omega_M$. Expressions in terms of $\gamma =\left(\Omega_{\Lambda} /\Omega_M\right)^{1/6}$ and its inverse are given, in particular reproducing Mattig's relation with a $O(\gamma^5)$ correction due to the cosmological constant.
