Growth of matter perturbations in clustered holographic dark energy cosmologies
Ahmad Mehrabi, Spyros Basilakos, Mohammad Malekjani +1
We investigate the growth of matter fluctuations in holographic dark energy cosmologies. First we use an overall statistical analysis involving the latest observational data in ord…
Gaugessence: a dark energy model with early time radiation-like equation of state
A. Mehrabi, A. Maleknejad, V. Kamali
In this work, we study a new quintessence model associated with non-Abelian gauge fields, minimally coupled to Einstein gravity. This gauge theory has been recently introduced and…
On the possibility of magnetic field detection on a microlensed source star
Ahmad Mehrabi, Habib khosroshahi, Hadi Rahmani
In a microlensing event, a large magnification occurs at caustic crossing and provides an opportunity to obtain a stronger signal associated with the object. In this paper we study…
How clustering dark energy affects matter perturbations
A. Mehrabi, S. Basilakos, F. Pace
The rate of structure formation in the Universe is different in homogeneous and clustered dark energy models. The degree of dark energy clustering depends on the magnitude of its e…
