Radiation from a D-dimensional collision of shock waves: an insight allowed by the D parameter

Abstract

We consider the radiation emitted in a collision of shock waves, in D-dimensional General Relativity (GR), and describe a remarkably simple pattern, hinting at a more fundamental structure, unveiled by the introduction of the parameter D.
