An inhomogeneous alternative to dark energy?
Havard Alnes, Morad Amarzguioui, Oyvind Gron
Recently, there have been suggestions that the apparent accelerated expansion of the universe is not caused by repulsive gravitation due to dark energy, but is rather a result of i…

Cosmological constraints on f(R) gravity theories within the Palatini approach
M. Amarzguioui, O. Elgaroy, D. F. Mota +1
We investigate f(R) theories of gravity within the Palatini approach and show how one can determine the expansion history, H(a), for an arbitrary choice of f(R). As an example, we…

Can a dust dominated universe have accelerated expansion?
H. Alnes, M. Amarzguioui, O. Gron
Recently, there has been suggestions that the apparent accelerated expansion of the universe is due not to a cosmological constant, but rather to inhomogeneities in the distributio…
