Description
Reheating phase of inflationary Universe can be modeled by parameters Treh, reh and Nreh, which can be constrained by the scalar spectral amplitude As and the scalar spectral index ns. On the other hand the low multipole anomalies in the CMB can be modeled by suitable features in the inflaton potential. We show that the parameters of these features in the inflaton potential provide additional constraints on the reheating parameters. For several single field models we find that the reheating parameters are substantially more constrained by the requirement of compatibility with the proposed explanation for low multipole anomalies.
