Asymptotically AdS spacetimes and isometric embeddings

Abstract: We present a simple isometric embedding of the nonrotating BTZ black hole spacetime into (3+2)-dimensional Minkowski space and (3+1)-dimensional mathematical AdS space. A one parameter family of embeddings of the physical (2+1) AdS space (i.e. the universal covering of AdS) is obtained by a double Wick rotation from the BTZ case.
Asymptotic structure in higher dimensional spacetimes and its classification

Abstract: I will discuss the asymptotic structure in higher dimensional spacetimes, especially at null infinity of asymptotically flat spacetimes.
Black Hole collisions

Abstract: We review the topic of black hole collisions. We will give an overview of what has been done so far in four dimensional vacuum gravity and we expand on our group's recent efforts of performing black hole collisions in asymptotically de Sitter spaces, Einstein-Maxwell theory and higher-dimensional vacuum gravity.

From Black Holes to Naked Singularities in Gravitational Collapse

Abstract: We give a brief overview of naked singularities, how these can form from gravitational collapse and their possible relevance in astrophysics. We investigate how the black hole formation process described by the Oppenheimer-Snyder scenario is affected once small pressures are introduced in the collapsing matter cloud.
