Observational Constraints on the Generalized Chaplygin Gas
نویسنده
چکیده
In this paper we study a quintessence cosmological model in which the dark energy component is considered to be the Generalized Chaplygin Gas and the curvature of the three-geometry is taken into account. Two parameters characterize this sort of fluid, the ν and the α parameters. We use different astronomical data for restricting these parameters. It is shown that the constraint ν . α agrees enough well with the astronomical observations.

Generalized Chaplygin gas as a unified scenario of dark matter/energy: observational constraints
Although various cosmological observations congruously suggest that our universe is dominated by two dark components, the cold dark matter without pressure and the dark energy with negative pressure, the nature and origin of these components is yet unknow. The generalized Chaplygin gas (gCg), parametrized by an equation of state, p = −A/ραgCg, was recently proposed to be a candidate of the unif...
متن کاملObservational Constraints on Variable Chaplygin Gas
We investigate observational constraints on the variable Chaplygin gas model from the gold sample of type Ia supernova data and the recent measurements of the X-ray gas mass fractions in galaxy clusters. Combining these databases, we obtain a tight constraint on the two model parameters. Our results indicate that the original Chaplygin gas model is ruled out by the data at 99.7% confidence leve...
متن کاملViscous generalized Chaplygin gas as a unified dark fluid: including perturbation of bulk viscosity
In this paper, we continue our previous work of studying viscous generalized Chaplygin gas as a unified dark fluid but the bulk viscosity perturbations. By using the currently available cosmic observational data from SNLS3, BAO, HST, and recently released Planck, we obtain a constraint on the bulk viscosity coefficient: ζ0 = 0.0000138+0.00000614+0.0000145+0.0000212 −0.0000105−0.0000138−0.000013...
متن کاملConstraints on the generalized Chaplygin gas model including gamma-ray bursts via a Markov Chain Monte Carlo approach
Aims. We investigate observational constraints on the generalized Chaplygin gas (GCG) model including the gamma-ray bursts (GRBs) at high redshift obtained directly from the Union2 type Ia supernovae (SNe Ia) set. Methods. By using the Markov Chain Monte Carlo method, we constrain the GCG model with the cosmology-independent GRBs, as well as the Union2 set, the cosmic microwave background (CMB)...
متن کاملInteracting Modified Variable Chaplygin Gas in a Non-flat Universe
We have presented a more generalized model of interacting Chaplygin gas. The effective equation of states corresponding to matter and dark energy have been derived in this generalized model. Moreover, the case of phantom energy arises by putting some constraints on the parameters involved.
