Thermalised dark radiation in the presence of PBH: and gravitational waves complementarity
Nayan Das, Suruj Jyoti Das, Debasish Borah
We study the possibility of detecting dark radiation (DR) produced by a combination of interactions with the thermal bath and ultra-light primordial black hole (PBH) evaporation in…

Freeze-in Dark Matter via Light Dirac Neutrino Portal
Anirban Biswas, Debasish Borah, Nayan Das +1
We propose a scenario where dark matter (DM) can be generated non-thermally due to the presence of a light Dirac neutrino portal between the standard model (SM) and dark sector par…

Inflation and Reheating in f(R,h) theory formulated in the Palatini formalism
Nayan Das, Sukanta Panda
A new model for inflation using modified gravity in the Palatini formalism is constructed. Here non-minimal coupling of scalar field h with the curvature R as a general function f(…
