Charged gravastars admitting conformal motion
A A Usmani, Farook Rahaman, Saibal Ray +4
We propose a new model of a {\it gravastar} admitting conformal motion. While retaining the framework of the Mazur-Mottola model, the gravastar is assumed to be internally charged,…
On the energy of Hořava-Lifshitz black holes
I. Radinschi, F. Rahaman, A. Banerjee
In this paper we calculate the energy distribution of the Mu-in Park, Kehagias-Sfetsos (KS) and Lü, Mei and Pope (LMP) black holes in the Hořava-Lifshitz theory of gravity. These b…
Galactic rotation curves inspired by a noncommutative-geometry background
F. Rahaman, Peter K. F. Kuhfittig, K. Chakraborty +2
This paper discusses the observed at rotation curves of galaxies in the context of noncommutative geometry. The energy density of such a geometry is diffused throughout a region du…
Perfect Fluid Dark Matter
F. Rahaman, K. K. Nandi, A. Bhadra +2
Taking the flat rotation curve as input and treating the matter content in the galactic halo region as perfect fluid, we obtain space time metric at the galactic halo region in the…
Five Dimensional Cosmological Models in General Relativity
R. K. Tiwari, Farook Rahaman, Saibal Ray
A Five dimensional Kaluza-Klein space-time is considered in the presence of a perfect fluid source with variable G and . An expanding universe is found by using a relation betwe…
Singularity-free solutions for anisotropic charged fluids with Chaplygin equation of state
Farook Rahaman, Saibal Ray, Abdul Kayum Jafry +1
We extend the Krori-Barua analysis of the static, spherically symmetric, Einstein-Maxwell field equations and consider charged fluid sources with anisotropic stresses. The inclusio…
