Time evolution of the equation of state during perturbative reheating and its impact on the inflationary tensor perturbation spectrum
Avirup Ghosh, Deep Ghosh
The spectrum of inflationary tensor perturbations is one of the very few available probes of the post-inflationary reheating epoch, and it is strongly influenced by the Universe's…

Prospects of measuring the atmospheric muon neutrino and anti-neutrino flux ratio with the ATLAS detector
Deep Ghosh, Satyanarayan Mukhopadhyay, Biswarup Mukhopadhyaya
There is a significant uncertainty in the prediction of atmospheric muon neutrino and anti-neutrino flux ratio using different flux models, especially at higher energies. We study…

Improved Treatment of Bosonic Dark Matter Dynamics in Neutron Stars: Consequences and Constraints
Koushik Dutta, Deep Ghosh, Biswarup Mukhopadhyaya
It is conceivable that a bosonic dark matter (DM) with non-gravitational interactions with SM particles will be accumulated at the center of a neutron star (NS) and can lead to bla…
