We analyze the redshift suffered by photons originating from an external source, traversing a collapsing dust cloud and finally being received by an asymptotic observer. In additio…

On the behaviour of non-radial null geodesics in self-similar Tolman-Bondi collapse
Néstor Ortiz, Olivier Sarbach, Thomas Zannias
Motivated by recent work on the structure of the singularity in inhomogeneous Tolman-Bondi collapse models, we investigate the behaviour of null geodesics in the particular case wh…
