title = "From pp-Waves to Galilean Spacetimes",
abstract = "We exhibit all spatially isotropic homogeneous Galilean spacetimes of dimension (n + 1) ≥ 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.",
