Theory and Numerics of Gravitational Waves from Preheating after Inflation
Jean Francois Dufaux, Amanda Bergman, Gary N. Felder +2
Preheating after inflation involves large, time-dependent field inhomogeneities, which act as a classical source of gravitational radiation. The resulting spectrum might be probed…
Weak Lensing of Baryon Acoustic Oscillations
Alberto Vallinotto, Scott Dodelson, Carlo Schimd +1
Baryon Acoustic Oscillations (BAO) have recently been observed in the distribution of distant galaxies. The height and location of the BAO peak are strong discriminators of cosmolo…
Quantization of perturbations during inflation in the 1+3 covariant formalism
Cyril Pitrou, Jean-Philippe Uzan
This note derives the analogue of the Mukhanov-Sasaki variables both for scalar and tensor perturbations in the 1+3 covariant formalism. The possibility of generalizing them to non…
