Viscous Inflationary Universe Models
TL;DR: In this article, the authors reviewed and carried further in inflationary cosmological models of Bianchi type-I with shear, bulk, and nonlinear viscosity.

The origin of galaxies: A review of recent theoretical developments and their confrontation with observation
TL;DR: There is a considerable body of data on galaxies; the problem is in deciding which kind of observation is most relevant to understanding the origin of galaxies as mentioned in this paper, and an attempt is made both to put the present research in its historical perspective and to stress the possibilities for future advances towards the goal of understanding the origins of cosmic structure.

Cosmological solutions of the Einstein equations with a causal viscous fluid
L P Chimento,A S Jakubi +1 more
TL;DR: In this paper, the authors investigated the behavior of the solutions to the Einstein equations with a causal viscous fluid source in the case of the spatially flat Robertson-Walker metric, and they found that the qualitative asymptotic behavior in the far future is not altered by relaxation processes, but they change the behaviour in the past.

On the structure of conformal singularities in classical general relativity
TL;DR: In this paper, the authors consider Big Bang singularities which can be conformally transformed to a spacelike hypersurface, with the conformal factor and conformal metric both smooth on the extended manifold.

Production of entropy and viscous damping of anisotropy in homogeneous cosmological models: Bianchi type-I spaces
N. Caderni,R. Fabbri +1 more
TL;DR: In this paper, the authors investigated world models in which strong initial anisotropies are damped out by viscous dissipation at temperatures lower than 1012K, and the corresponding entropy production is calculated and is proved to be simply related to the initialanisotropy.
