Probing the Perturbative Reheating History of Decaying Oscillatory Inflation with ACT Constraints

Li-Yang Chen, Rongrong Zhai, Feng-Yi Zhang

Precision measurements of the Cosmic Microwave Background (CMB) now offer a powerful probe of the unknown reheating epoch. In this work, we scrutinize a decaying oscillatory inflat…

Reconciling the ACT Preference in Gravity: Inflation and Reheating Constraints

Feng-Yi Zhang, Rongrong Zhai, Li-Yang Chen

Compared with the results of Planck-only analyses, recent measurements from the Atacama Cosmology Telescope (ACT) indicate a preference for a slightly bluer scalar spectral index,…
