RT Journal Article T1 Non-singular radiation cosmological models A1 Fernández Jambrina, Leonardo A1 González Romero, Luis Manuel AB In this paper we analyse the possibility of constructing singularity-free inhomogeneous cosmological models with a pure radiation field as matter content. It is shown that the conditions for regularity are very easy to implement and therefore there is a huge number of such spacetimes.
