We study gravitational baryogenesis in an isotropic and homogeneous universe the framework of general relativity. investigate a new exact solution Einstein’s field equations for FRW metric. Our represents transitioning model which was expanding decelerated mode passes on to accelerated after dominance cosmological constant $$\Lambda$$ . observe that occurs derived universe, baryon-entropy ratio is good agreement with its observational value.

Quasar Populations in a Cosmological Constant Dominated Flat Universe
Most physical properties derived for quasars, as single entities or as a population, depend upon the cosmology assumed. In this paper, we calculate the quasar luminosity function and some related quantities for a at universe dominated by a cosmological constant ((= 0:9; = 0:1) and compare them with those deduced for a at universe with zero cosmological constant ((= 0; = 1). We use the AAT quasa...
متن کاملFuture Evolution of Nearby Large-Scale Structure in a Universe Dominated by a Cosmological Constant
We simulate the future evolution of the observed inhomogeneities in the local universe assuming that the global expansion rate is dominated by a cosmological constant. We find that within two Hubble times (∼ 30 billion years) from the present epoch, large-scale structures will freeze in comoving coordinates and the mass distribution of bound objects will stop evolving. The Local Group will get ...
متن کاملFuture Evolution of the Intergalactic Medium in a Universe Dominated by a Cosmological Constant
We simulate the evolution of the intergalactic medium (IGM) in a universe dominated by a cosmological constant. We find that within a few Hubble times from the present epoch, the baryons will have two primary phases: one phase composed of low-density, low-temperature, diffuse, ionized gas which cools rapidly with cosmic time due to adiabatic exponential expansion, and a second phase of high-den...
متن کاملGravitational Perfect Fluid Collapse With Cosmological Constant
In this paper, the effect of a positive cosmological constant on spherically symmetric collapse with perfect fluid has been investigated. The matching conditions between static exterior and non-static interior spacetimes are given in the presence of a cosmological constant. We also study the apparent horizons and their physical significance. It is concluded that the cosmological constant slows ...
متن کاملVanishing Cosmological Constant via Gravitational S-Duality
We study S-duality transformations that mix the graviton with various forms of matter. In the case of matter in the form of a 3-form field, the dual of an (A)dS space time – with arbitrary curvature – is seen to be flat Minkowski space time, if the 3-form field has vanishing field strength before the duality transformation. Then we show that the Schwarzschild metric can be obtained as a suitabl...
