Two phase reheating: CMB constraints on inflaton and dark matter phenomenology
Md Riajul Haque, Debaprasad Maity, Pankaj Saha
We propose a two-phase reheating scenario where the initial preheating dynamics is described by an effective dynamics followed by the standard perturbative reheating. Some of the i…
PBHs and secondary GWs from ultra slow roll and punctuated inflation
H. V. Ragavendra, Pankaj Saha, L. Sriramkumar +1
[Abridged] The primordial scalar power spectrum is well constrained on large scales, primarily by the observations of the anisotropies in the cosmic microwave background (CMB). Ove…
Accounting for the time evolution of the equation of state parameter during reheating
Pankaj Saha, Sampurn Anand, L. Sriramkumar
One of the important parameters in cosmology is the parameter characterizing the equation of state (EoS) of the sources driving the cosmic expansion. Epochs that are dominated by r…
