Interaction of Bianchi Type-I Anisotropic Cloud String Cosmological Model Universe with Electromagnetic Field

Here, we have investigated the interaction of Bianchi type I anisotropic cloud string cosmological model universe with electromagnetic field in the context of general relativity. In this paper, the energy momentum tensor is assumed to be the sum of the rest energy density and string tension density with an electromagnetic field. To obtain exact solutions of Einstein field equations, we take average scale factor as an integrating function of time. Also, the dynamics and significance of various physical parameters of model are discussed.

Anisotropic Cloud String Cosmological Model With Bianchi Type-I Space-Time in General Relativity

Anisotropic cloud string cosmological model with Bianchi type I space time is investigated in the context of general relativity. The exact solutions of Einstein field equations are obtained with when the source for energy momentum tensor is generated by a cloud of strings with particles attached to them. The dynamical and physical properties of the model universe are discussed by comparing with the present observational findings. The interesting feature obtained here is that our model universe starts with a big bang and as time passes both particle density and string tension density decreases with expansion of our Universe so that in the late time string vanishes and thus leaving only the particles.
