From pp-Waves to Galilean Spacetimes

Abstract

We exhibit all spatially isotropic homogeneous Galilean spacetimes of dimension $(n+1)\ge 4$, including the novel torsional ones, as null reductions of homogeneous pp-wave spacetimes. We also show that the pp-waves are sourced by pure radiation fields and analyse their global properties.
