Quintom dark energy in DGP braneworld cosmology
In this paper we consider a Z2 symmetrical 3-brane embedded in a 5-dimensional spacetime. We study the effective Einstein equation and acceleration condition in presence of the quintom dark energy fluid as the bulk matter field. The effective Einstein equation on the brane in the framework of DGP model is obtained where the quintom field is considered as the bulk matter field, and a quintom dar...
متن کاملDark Matter in Cosmology
The last two decades in cosmological research have been an exciting time, and produced an exciting product: we now have in hand a “standard model” of cosmology. While several aspects of this model remain mysterious, its predictions are in remarkable accord with a vast range of observational data. A key aspect of this model, and one of the aforementioned mysteries, is the dark matter: a cold, co...
متن کاملQuintom dark energy in the DGP braneworld cosmology
In this paper we consider a Z2 symmetrical 3-brane embedded in a 5-dimensional spacetime. We study the effective Einstein equation and acceleration condition in presence of the quintom dark energy fluid as the bulk matter field. It is shown that the time-dependent bulk quintom field induces a time-dependent cosmological constant on the brane. In the framework of the DGP model, the effective Ein...
متن کاملHot Dark Matter in Cosmology
1 Historical Summary Cosmological dark matter in the form of neutrinos with masses of up to a few electron volts is known as hot dark matter. In 1979-83, this appeared to be perhaps the most plausible dark matter candidate. Such HDM models of cosmological structure formation led to a top-down formation scenario, in which superclusters of galaxies are the first objects to form, with galaxies and...
