As first discovered by Choptuik, the black hole threshold in the space of initial data for
general relativity shows both surprising structure and surprising simplicity. Universality …

It is now known that when a massive star collapses under the force of its own gravity, the
final fate of such a continual gravitational collapse will be either a black hole or a naked …

We develop here a new procedure within Einstein's theory of gravity to generate equilibrium
configurations that result as the final state of gravitational collapse from regular initial …

In general relativity black holes can be formed from regular initial data that do not contain a
black hole already. The space of regular initial data for general relativity therefore splits …

We give a model of the higher-dimensional spherically symmetric gravitational collapse of a
dust cloud including the perturbative effects of quantum gravity. The n (≥ 5)-dimensional …

An outstanding problem in gravitation theory and relativistic astrophysics today is to
understand the final outcome of an endless gravitational collapse. Such a continual collapse …

Gravitational collapse is one of the most fruitful subjects in gravitational physics. It is well
known that singularity formation is inevitable in complete gravitational collapse. It was …

We investigate here spherically symmetric gravitational collapse in a space-time with an
arbitrary number of dimensions and with a general type I matter field, which is a broad class …

In 1990, based on numerical and formal asymptotic analysis, Ori and Piran predicted the
existence of selfsimilar spacetimes, called relativistic Larson-Penston solutions, that can be …

We investigate a class of three parameter metrics that contain both the γ-metric and Janis-
Newman-Winicour (JNW) metric at special values of the parameters. To see the effect of the …
