Penn State Numerical Relativity Group

Our group studies some of the most energetic phenomena in the Universe, such as colliding neutron stars and black holes or the explosion of massive stars, using supercomputer simulations.

The visualization on the right shows the matter density from a simulation two colliding neutron stars. The less massive star is tidally deformed by the primary star prior to merger. The image also shows how the spacetime fabric is bent by the two stars as they orbit each other (more precisely we are showing an elevation plot of the lapse function).

We are members of the CoRe collaboration, and we make our simulation code and data publicly available at on the CoRe website and on Zenodo.
