Linear perturbations of self-gravitating spherically symmetric configurations
Eliana Chaverra, Néstor Ortiz, Olivier Sarbach
We present a new covariant, gauge-invariant formalism describing linear metric perturbation fields on any spherically symmetric background in general relativity. The advantage of t…

Conformal diagrams for the gravitational collapse of a spherically symmetric dust cloud
Néstor Ortiz, Olivier Sarbach
We present an algorithm for the construction of conformal coordinates in the interior of a spherically symmetric, collapsing matter cloud in general relativity. This algorithm is b…

Initial data giving rise to naked singularities in spherically symmetric dust collapse
Néstor Ortiz
The phase space corresponding to a particular four-parameter family of initial data for the gravitational collapse of a spherically symmetric dust cloud is investigated. In a certa…
