Revisiting the history of the evolution of the universe from radiation dominated to dark energy dominated
Muhammad Yarahmadi, Amin Salehi
Most of our knowledge of the universe has been obtained from the anisotropy spectrum of the cosmic microwave background and observations of large-scale structures. During the histo…
Cosmography of chameleon gravity
Amin. Salehi
The paper discusses a particular model of chameleon gravity where the scalar field has an exponential as and an exponential coupling to the matter…
Does stability in Einstein frame guarantee stability in Jordan frame?
Amin Salehi
Scalar tensor theories of gravity can be formulated in the Einstein or in the Jordan frame, which are related by the conformal transformations. Although the two frames are describe…
Searching for Cosmological Preferred Axis using cosmographic approach
Amin Salehi, Mohammad Reza Setare
Recent released Planck data and other astronomical observations show that the universe may be anisotropic on large scales. This hints a cosmological privileged axis in our anisotro…
Phase plane analysis and statefinder diagnostic of agegraphic dark energy in 5D Brans-Dicke cosmology
Amin Salehi, Hossein Farajollahi, Jafar Sadeghi +1
We present an autonomous phase-plane describing the evolution of field equations containing an agegraphic dark energy in 5D Brans- Dicke cosmology. To observationally verify the nu…
Searching for a Cosmological Preferred Axis in complicated class of cosmological models:Case study model
Amin Salehi, S. Aftabi
Recent astronomical observations show that the universe may be anisotropic on large scales. The Union2 SnIa data hint that the universe has a preferred direction. If such a cosmolo…
