The observable universe could be a 1+ 3-surface (the “brane”) embedded in a 1+ 3+ d-
dimensional spacetime (the “bulk”), with Standard Model particles and fields trapped on the …

We start by reviewing the existing literature on the creation of black holes during high-
energy particle collisions, both in the absence and in the presence of extra, compact …

The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

The minimal geometric deformation approach was introduced in order to study the exterior
spacetime around spherically symmetric self-gravitating systems, such as stars or similar …

The general parametrization for spacetimes of spherically symmetric Lorentzian, traversable
wormholes in an arbitrary metric theory of gravity is presented. The parametrization is similar …

In the context of the Randall-Sundrum braneworld, the minimal geometric deformation
approach<? format?> is used to generate an analytic interior solution to four-dimensional …

The condition R= 0, where R is the four-dimensional scalar curvature, is used for obtaining a
large class (with an arbitrary function of r) of static, spherically symmetric Lorentzian …

Gravitational lensing by traversable Lorentzian wormholes is a new possibility which is
analyzed here in the strong field limit. Wormhole solutions are considered in the Einstein …

We study strong gravitational lensing by a class of static wormhole geometries. Analytical
approaches to the same are developed, and the results differ substantially from strong …

Echoes are known as modifications of the usual quasinormal ringing of a black hole at late
times because of the deviation of space-time from the initial black hole geometry in a small …
