Observational Constraints of New Variable Modified Chaplygin Gas Model
Jhumpa Bhadra, Ujjal Debnath
Assuming the flat FRW universe in Einstein's gravity filled with New Variable Modified Chaplygin gas (NVMCG) dark energy and dark matter having negligible pressure. In this researc…
Large Dynamical System Analysis for Anisotropic Universe in Brans-Dicke Theory
Jhumpa Bhadra, Shuvendu Chakraborty, Ujjal Debnath
In this work, we have studied the Brans-Dicke (BD) cosmology in anisotropic models. We present three dimensional dynamical system describing the evolution of anisotropic models con…
Accretion of New Variable Modified Chaplygin Gas and Generalized Cosmic Chaplygin Gas onto Schwarzschild and Kerr-Newman Black holes
Jhumpa Bhadra, Ujjal Debnath
In this work, we have studied accretion of the dark energies NVMCG and GCCG onto the Schwarzschild and Kerr-Newman Black holes. We find the expression of the critical four velocity…
Dynamical System Analysis of Interacting Variable Modified Chaplygin Gas Model in FRW Universe
Jhumpa Bhadra, Ujjal Debnath
In this work, we have considered interacting dynamical model taking variable modified Chaplygin gas which plays as dark energy coupled to cold dark matter in the flat FRW universe.…
