The Age-Redshift Relation for Standard Cosmology
R. C. Thomas, R. Kantowski
Abstract
We present compact, analytic expressions for the age-redshift relation τ(z) for standard Friedmann-Lema\ -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.
