    • Abstract

       

      In this paper we study the bulk viscous cosmology by considering modified Chaplygin gas in the framework of ($2 + 1$)-dimensional spacetime. For this we consider various form of bulk viscosity coefficient $\zeta$ and then obtain the physical parameters energy density $\rho$, Hubble and deceleration parameters, $H$ and $\rho$, respectively. Finally we discuss the stability of the model by using the speed of sound.

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
