From inflation to late acceleration: A new cosmological paradigm
Supratik Pal
A new idea of deriving a cosmological term from an underlying theory has been proposed in order to explain the expansion history of the universe. We obtain the scale factor with th…
Cosmological consequences of generalised RS II braneworlds
Supratik Pal
We discuss certain features of cosmology in a generalised RS II braneworld scenario. In this scenario, the bulk is given by a Schwarzschild-anti de Sitter or a Vaidya-anti de Sitte…
Brane cosmology, Weyl fluid, and density perturbations
Supratik Pal
We develop a technique to study relativistic perturbations in the generalised brane cosmological scenario, which is a generalisation of the multi-fluid cosmological perturbations t…
Bouncing Braneworld with Born-Infeld and Gauss-Bonnet
Sudipta Mukherji, Supratik Pal
We show the existence of some bouncing cosmological solutions in the braneworld scenario. More specifically, we consider a dynamical three-brane in the background of Born-Infeld an…
