Probing the shape of the primordial curvature power spectrum and the energy scale of reheating with pulsar timing arrays
Lele Fan, Jie Zheng, Fengge Zhang +1
The stochastic gravitational wave background (SGWB) provides a unique opportunity to probe the early Universe, potentially encoding information about the primordial curvature power…

Primordial black holes and scalar induced gravitational waves from the model with a Gauss-Bonnet term
Fengge Zhang
We study an inflationary model with the Gauss-Bonnet coupling, which can enhance the curvature perturbation at small scales and thus produce a significant abundance of primordi…
