Testing Cosmological Models and Understanding Cosmological Parameter Determinations with Metaparameters
Cosmological parameters affect observables in physically distinct ways. For example, the baryon density, ωb, affects the ionization history and also the pressure of the pre-recombination fluid. To investigate the relative importance of different physical effects to the determination of ωb, and to test the cosmological model, we artificially split ωb into two ‘metaparameters’: ωbe which controls...
متن کاملTesting Cosmological Models with Negative Pressure
There is now strong evidence that the main contribution to the cosmic energy density is not due to matter, but to another component with negative pressure. Its nature is still unknown: it could be the vacuum energy, manifesting itself as a positive cosmological constant with w ≡ P/ρc2 = −1 (ΛCDM model), a spatially inhomogeneous and dynamically evolving form of energy with −1 < w < 0 (quintesse...
متن کاملMultidimensional cosmological models: cosmological and astrophysical implications
We investigate four-dimensional effective theories which are obtained by dimensional reduction of multidimensional cosmological models with factorizable geometry and consider the interaction between conformal excitations of the internal space (geometrical moduli excitations) and Abelian gauge fields. It is assumed that the internal space background can be stabilized by minima of an effective po...
متن کاملCosmological Models with Variable Deceleration Parameter in Lyra’s Manifold
FRW models of the universe have been studied in the cosmological theory based on Lyra’s manifold. A new class of exact solutions has been obtained by considering a time dependent displacement field for variable deceleration parameter from which three models of the universe are derived (i) exponential (ii) polynomial and (iii) sinusoidal form respectively. The behaviour of these models of the un...
متن کاملTesting and selection cosmological models with dark energy
It is described dynamics of a large class of accelerating cosmological models in terms of dynamical systems of the Newtonian type. The evolution of the models is reduced to the motion of a particle in a potential well parameterized by the scale factor. This potential function can be reconstructed from distant supernovae type Ia data and many cosmological models represented in terms of the poten...
