ABSTRACT

A new analytical solution for the luminosity distance in flat ΛCDM cosmology is derived in terms of elliptical integrals of first kind with real argument. The consequent derivation of the distance modulus allows evaluating the Hubble constant, H₀=69.77±0.33, Ω_M=0.295±0.008, and the cosmological constant,
