The gravitational redshift of photons traversing a collapsing dust cloud and observable consequences
Néstor Ortiz, Olivier Sarbach
We analyze the frequency shift of photons propagating on an asymptotically flat spacetime describing a collapsing, spherical dust cloud. We focus on the case where the interaction…

Cauchy horizon stability in a collapsing spherical dust cloud I: geometric optic approximation and spherically symmetric test fields
Néstor Ortiz, Olivier Sarbach
A spherical dust cloud which is initially at rest and which has a monotonously decaying density profile collapses and forms a shell-focussing singularity. Provided the density prof…
