چکیده

We provide a new electromagnetic mass model admitting Chaplygin gas equation of state. We investigate three specializations, the first characterized by a vanishing effective pressure, the second provided with a constant effective density and the third is described by a constant effective pressure p0. For these specializations two particular cases are discussed: (1) σe λ 2 = σ0, and (2) σe λ 2 = σ0r , where σ, σ0, λ and s represents the charge density of the spherical distribution, charge density at the center of the system, metric potential and a constant, respectively. In addition, for specialization I, case I we found isotropic coordinate as well as Kretschmann scalar, and for specialization III, case II two special scenarios have been studied.

Cosmic Walls and Filaments Formation in Modied Chaplygin Gas Cosmology

We want to study the perturbation growth of an initial seed of an ellipsoidal shape in Top-Hat collapse model of the structure formation in the Modied Chaplygin gas cosmology. Considering reasonable values of the constants and the parameters of the model under study, we can show that a very small deviation from spherical symmetry (ellipsoidal geometry) in the initial seed leads to a nal highly ...

Generalized Holographic Dark Energy Model

In this paper, the model of the holographic Chaplygin gas has been extended to two general cases: first the case of a modified variable Chaplygin gas and second the case of the viscous generalized Chaplygin gas. The dynamics of the model is expressed by the use of scalar fields and scalar potentials.

Cosmology with a Variable Chaplygin Gas

We consider a new generalized Chaplygin gas model that includes the original Chaplygin gas model as a special case. In this model the generalized Chaplygin gas evolves as from dust to quiessence or phantom. We show that the model is consistent with current type Ia supernova data for a broad range of parameters.

Gravitational waves in the generalized Chaplygin gas model

The consequences of taking the generalized Chaplygin gas as the dark energy constituent of the Universe on the gravitational waves are studied and the spectrum obtained from this model, for the flat case, is analyzed. Besides its importance for the study of the primordial Universe, the gravitational waves represent an additional perspective (besides the CMB temperature and polarization anisotro...
