We review constructions of three-dimensional 'quantum'black holes. Such spacetimes arise
via holographic braneworlds and are exact solutions to an induced higher-derivative theory …

The literature features many instances of spacetimes containing two black holes held apart
by a thin distribution of matter (strut or strings) on the axis joining the holes. For all such …

The topic of this thesis is the modelling of gravitational waves for perturbed black holes, and
consists of three manuscripts. To do this, we work mainly within two relevant regimes that …

We review constructions of three-dimensional 'quantum'black holes. Such spacetimes arise

We investigate string or branelike solutions for four-dimensional vacuum Einstein equations
in the presence of a cosmological constant. For the case of negative cosmological constant …

For the five-dimensional spacetimes whose four-dimensional sections are static, spherically
symmetric (SO (3)), and flat asymptotically, we study the behavior of Arnowitt-Deser-Misner …

We study the creation of a black hole (BH) pair separated by a domain wall, in the presence
of a cosmological constant. We construct the solution representing a BH pair with a domain …

In this paper, we give a new class of solutions to the vacuum Einstein's field equations. This
class of solutions possesses the naked physical singularity, ie, no event horizon exists …
