Confronting Kähler moduli inflation with CMB data
Sukannya Bhattacharya, Koushik Dutta, Mayukh R. Gangopadhyay +1
In models of inflation obtained from string compactification, moduli vacuum misalignment leads to an epoch in the post-inflationary history of the universe when the energy density…
Constraining Warm Inflation with CMB data
Mar Bastero-Gil, Sukannya Bhattacharya, Koushik Dutta +1
We confront the warm inflation observational predictions directly with the latest CMB data. We focus on a linear temperature (T) dissipative coefficient combined with the simplest…
Constraints on Kähler moduli inflation from reheating
Sukannya Bhattacharya, Koushik Dutta, Anshuman Maharana
We present predictions of the Kähler moduli inflation model for the spectral tilt by parametrising the reheating epoch by an effective equation-of-state parameter and the number of…
Attractor Models in Scalar-Tensor Theories of Inflation
Sukannya Bhattacharya, Kumar Das, Koushik Dutta
In this work we study the cosmological attractor models of inflation in connection with certain scalar-tensor theories of gravity, e.g gravity and Brans-Dicke theory. For so…
