Understand

This is a supplement to an earlier paper (PRD 84, 023510 (2011)), where those shearfree normal cosmological models were identified, in which all light rays have repeatable paths.

All of them are conformally flat, but less general than the Stephani model and more general than Robertson --Walker.
In this note, their defining feature is identified: in each of them, in comoving coordinates, the time-dependence factors out so that the cofactor is a static metric.
Some related properties of conformal transformations are briefly discussed.
