Abstract

We present compact, analytic expressions for the age-redshift relation \ensuremathτ(z) for standard Friedmann-Lema\^\itre-Robertson-Walker (FLRW) cosmology. The new expressions are given in terms of incomplete Legendre elliptic integrals and evaluate much faster than by direct numerical integration.
