Black Hole Scattering with Numerical Relativity
![N/A](/sites/default/files/styles/large/public/migrated2016/images/Hirotada%20Okawa.jpg?itok=Db5HdZmX)
Abstract: Numerical relativity in higher dimensional spacetimes has been one of powerful tools to study various phenomina such as the stability of higher dimensional black holes and the verification for higher dimensional gravity.

Asymptotically AdS spacetimes and isometric embeddings
![N/A](/sites/default/files/styles/large/public/migrated2016/images/Swillison.jpg?itok=Nl4jquUa)
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
![N/A](/sites/default/files/styles/large/public/migrated2016/images/KentaroTanabe.jpg?itok=TjvJSIwW)
Abstract: I will discuss the asymptotic structure in higher dimensional spacetimes, especially at null infinity of asymptotically flat spacetimes.
Black Hole collisions
![N/A](/sites/default/files/styles/large/public/migrated2016/images/Zilhao.jpg?itok=Nem_yaO0)
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.
