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 ...
متن کاملChaplygin Gas , Energy Conditions and Cosmology
It is explored that if dominant component of content of the future universe behaves as Chaplygin gas, voilation of other energy conditions (null energy condition, weak energy condition and dominant energy condition) can be avoided if " strong energy condition " is obeyed. In the investigations, here, two cases arise. In one case, universe expands with acceleration leading to finite energy densi...
متن کاملNew Approach to Chaplygin Gas Cosmology
We consider a new approach for Chaplygin cosmology, in which the relativistic formulation of Chaplygin matter is of crucial importance. Our results show that (for all times) the universe consists of a novel form of matter with dust like density (∼ (volume) −1) and negative pressure. This is in contrast to the usual Chaplygin cosmology, based on non-relativistic equation of state, that implies a...
متن کاملNew Results in Chaplygin Gas Cosmology
We provide a rigorous derivation of the evolution equation in the context of Chaplygin gas cosmology, in which the relativistic formulation of Chaplygin matter is a crucial ingredient. This is in contrast to the existing literature where the non-relativistic form of the Chaplygin equation of state is naively used in the covariant Einsstein equation. Our results show that the Chaplygin model des...
متن کاملCosmology 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.
