Observational constraints on the braneworld model with brane-bulk energy exchange
M. Sadegh Movahed, Ahmad Sheykhi
We investigate the viability of the braneworld model with energy exchange between the brane and bulk, by using the most recent observational data related to the background evolutio…
Consistency of Gravity with the Cosmological Observations in Palatini Formalism
M. Sadegh Movahed, Shant Baghram, Sohrab Rahvar
In this work we study the dynamics of universe in modified gravity with Palatini formalism. We use data from recent observations as Supernova Type Ia (SNI…
An Inhomogeneous Model Universe Behaving Homogeneously
Sh. Khosravi, E. Kourkchi, R. Mansouri +1
We present a new model universe based on the junction of FRW to flat Lemaitre-Tolman-Bondi (LTB) solutions of Einstein equations along our past light cone, bringing structures with…
Observational Constraints with Recent Data on the DGP Modified Gravity
M. Sadegh Movahed, Marzieh Farhang, Sohrab Rahvar
We study one of the simplest covariant modified-gravity models based on the Dvali-Gabadadze-Porrati (DGP) brane cosmology, a self-accelerating universe. In this model gravitational…
Power-law Parameterized Quintessence Model
Sohrab Rahvar, M. Sadegh Movahed
We introduce a power-law parameterized quintessence model for the dark energy which accelerate universe at the low redshifts while behaves as an ordinary matter for the early unive…
Quantum Effects and Cluster Formation
Ali Shojai, Fatimah Shojai
The causal interpretation of quantum mechanics is applied to the universe as a whole and the problem of cluster formation is studied in this framework. It is shown that the quantum…
