Estimation of the Parameters of Warm Inflationary Models

Observations of the temperature anisotropies in the Cosmic Microwave Background (CMB) radiation reveal key information about the early Universe phenomenon that possibly generated them, known as inflation. Here we study some single field monomial potential models of warm inflation and estimate their parameters that are consistent with the observations. We also obtain the n<inf>s</inf> and r values for these models and find them to be within the Planck allowed range, implying that these are observationally viable models in the context of warm inflation. Also, the values of the tensor-to-scalar ratio, r, for some of our models is within the sensitivity of the future CMB polarisation experiments, that can serve for the testability of these models.
