Stochastic gravitational waves from postinflationary structure formation
Benedikt Eggemeier, J. C. Niemeyer, Karsten Jedamzik, Richard Easther
Abstract
The authors study the (stochastic background) gravitational wave signal from the gravitational collapse of fluctuations in the inflation condensate following inflation and the signal's possible detection in current and future experiments. They manage to quantify this largely unexplored gravitational wave source in the primordial universe and show it might have present-day observable consequences, opening with this a potential window into the earliest moments after the Big Bang.
