On the Anisotropy of the Gravitational Wave Background from Massless Preheating
Laura Bethke, Daniel G. Figueroa, Arttu Rajantie
When a light scalar field is present during inflation, its value will vary on superhorizon scales, modulating the preheating process at the end of inflation. Consequently, the ampl…

Anisotropies in the Gravitational Wave Background from Preheating
Laura Bethke, Daniel G. Figueroa, Arttu Rajantie
We investigate the anisotropies in the gravitational wave (GW) background produced at preheating after inflation. Using lattice field theory simulations of a massless preheating mo…
