Dark energy and possible alternatives
M. Sami
We present a brief review of various approaches to late time acceleration of universe. The cosmological relevance of scaling solutions is emphasized in case of scalar field models…
Prospects of inflation with perturbed throat geometry
Amna Ali, R. Chingangbam, Sudhakar Panda +1
We study brane inflation in a warped deformed conifold background that includes general possible corrections to the throat geometry sourced by coupling to the bulk of a compact Cal…
Delicate f(R) gravity models with disappearing cosmological constant and observational constraints on the model parameters
Abha Dev, D. Jain, S. Jhingan +3
We study the theory of gravity using metric approach. In particular we investigate the recently proposed model by Hu-Sawicki, Appleby Battye and Starobinsky. In this mod…
