Polytropic Inspired Inflation on the Brane
Mohammad Reza Setare, Arvin Ravanpak, Hossein Farajollahi
The brane inflationary model inspired by a polytropic inflationary idea is studied. In the slow-roll approximation and high energy limit, for a chaotic potential, the model is deve…
Normal DGP in varying speed of light cosmology
Arvin Ravanpak, Hossein Farajollahi, Golnaz Farpoor Fadakar
The varying speed of light (VSL) has been used in cosmological models in which the physical constants vary over time. On the other hand, the Dvali, Gabadadze and Porrati (DGP) bran…
Probing Lambda-DGP Braneworld Model
A. Ravanpak, H. Farajollahi, G. F. Fadakar
In this article we study cosmic dynamics in the context of normal branch of DGP braneworld model. Using the current Planck data, we best fit the model and cosmological parameters i…
Thermodynamics and holography of tachyon cosmology
H. Farajollahi, A. Ravanpak, M. Abolghasemi
Recently, we have investigated the dynamics of the universe in tachyon cosmology with non-minimal coupling to matter \cite{faraj}-\cite{faraj3}. In particular, for the interacting…
Cosmological constraints on Agegraphic dark energy in DGP braneworld gravity
H. Farajollahi, A. Ravanpak, G. F. Fadakar
A proposal to study the original and new agegraphic dark energy in DGP braneworld cosmology is presented in this work. To verify our model with the observational data, the model is…
A 5D Holographic Dark Energy in DGP-Brane Cosmology
H. Farajollahi, A. Ravanpak
This paper is aimed at investigating a 5D holographic dark energy in DGP-BRANE cosmology by employing a combination of Sne Ia, BAO and CMB observational data to fit the cosmologica…
