Abstract This Living Review updates a previous version [25] which is itself an update of a
review article [31]. Numerical exploration of the properties of singularities could, in principle …

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 study the spherical collapse of a perfect fluid with an equation of state P= k ρ by full
general relativistic numerical simulations. For 0< k≲ 0. 0 3 6, it has been known that there …

We obtain a general spherically symmetric solution of a null dust fluid in n (⩾ 4) dimensions
in Gauss–Bonnet gravity. This solution is a generalization of the n-dimensional Vaidya …

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 addition, we …

We perform a detailed analysis of the properties of stationary observers located on the
equatorial plane of the ergosphere in a Kerr spacetime, including light-surfaces. This study …

Repulsive gravity is a well known characteristic of naked singularities. In this work, we
explore light surfaces and find new effects of repulsive gravity. We compare Kerr naked …

Gravitational collapse is one of the most striking phenomena in gravitational physics. The
cosmic censorship conjecture has provided strong motivation for research in this field. In the …

We find an exact solution in dimensionally continued gravity in arbitrary dimensions which
describes the gravitational collapse of a null dust fluid. Considering the situation where a …
