Non-thermal Hot Dark Matter from Inflaton/Moduli Decay: The Momentum Distribution and Relaxing the Cosmological Mass Bound
Sukannya Bhattacharya, Subinoy Das, Koushik Dutta +3
Decay of the inflaton or moduli which dominated the energy density of the universe at early times leads to a matter to radiation transition epoch. We consider non-thermal sterile d…
Implications of the NANOGrav result on primordial gravitational waves in nonstandard cosmologies
Sukannya Bhattacharya, Subhendra Mohanty, Priyank Parashari
Recently, the NANOGrav collaboration has reported evidence for a common-spectrum stochastic process, which might be interpreted as the first ever detection of stochastic gravitatio…
Non-thermal production of lepton asymmetry and dark matter in minimal seesaw with right handed neutrino induced Higgs potential
Rome Samanta, Anirban Biswas, Sukannya Bhattacharya
Within Type-I seesaw mechanism, Higgs mass can be dynamically generated via quantum effects of the right handed neutrinos assuming the potential is nearly conformal at the Ultra-Vi…
Fibre inflation and precision CMB data
Sukannya Bhattacharya, Koushik Dutta, Mayukh Raj Gangopadhyay +2
Generic features of models of inflation obtained from string compactifications are the correlations between the model parameters and the postinflationary evolution of the universe.…
