Modified Chaplygin gas in anisotropic universes on the brane

Abstract: In this paper, we study anisotropic universes with Modified Chaplygin gas (MCG) in the context of Randall Sundrum-2 (RS2) braneworld model. The cosmological solutions for Kantowski–Sachs (KS) and Bianchi-I universes with MCG are obtained on the RS2 braneworld. The solutions are found to be dependent on MCG parameters but are modified from the GR solutions due to the braneworld correction term arising from high-energy effects. The anisotropy and deceleration parameters are obtained for each solution and the pos… Show more

“…MCG has also been found to be consistent with observational tests like gravitational lensing test [38,39] and gamma ray bursts [40]. The observational constraints on MCG have also been studied in some detail [41][42][43][44][45][46]. In a recent work, Benaoum et al [47] have constructed some modified class of MCG models using geometrothermodynamics those show internal thermodynamic interactions.…”

“…Their first model consisted of two parallel braneworlds, but in the second model [19] the brane with a negative tension was moved to infinity. The RS single brane model has a spacelike extra dimension and finds wide range of application in both cosmology [26][27][28][29][30][31][32][33][34] and astrophysics [35][36][37][38][39][40][41][42][43][44]. Soon after, a dual to the RS-II single brane model was proposed by Shtanov and Sahni (SS), with a timelike extra dimension replacing…”
