We explore the possibility of a non-singular bounce in our universe from warped braneworld scenario with dynamical branes and non-zero brane cosmological constant. Such models naturally incorporate scalar sector known as radion originating modulus theory. The presence constant renders to be non-flat gives rise potential non-canonical kinetic term for field four dimensional effective action. exh...

We solve for the behaviour of cosmological perturbations in the Dvali-Gabadadze-Porrati (DGP) braneworld model using a new numerical method. Unlike some other approaches in the literature, our method uses no approximations other than linear theory and is valid on large scales. We examine the behaviour of late-universe density perturbations for both the self-accelerating and normal branches of D...
