Interests: viscous cosmology; multcomponent fluids; modified gravity and fluids; fluids and branes; electromagnetic aspects in the cosmic fluid
Recent investigations in general relativity and cosmology have shown the usefulness of taking into account realistic properties of the cosmic fluid, such as viscosity (shear and bulk), turbulence, multicomponent properties, etc. The objective of the present volume is to focus on these kind of properties, from different viewpoints, therewith adding to the physical understanding of the cosmic fluid. We would like like to call for papers disseminating and sharing recent findings on a diversity of topics, including but not restricted to:
- viscous cosmology
- the role of viscosity in regard to the phantom/quintessence epochs
- multicomponent fluids
- future singularities
- entropy issues
- the role of the Casimir effect in cosmology
- modified gravity
- electromagnetic effects in the cosmic fluid
Also, review papers are welcome.

Title: Large Scale Cosmological Anomalies and Inhomogeneous Dark Energy
Author: Leandros Perivolaropoulos
Affiliation: Department of Physics, University of Ioannina, Greece; E-Mail: email@example.com
Abstract: A wide range of large scale observations hint towards the requirement of possible modifications on the standard coosmological model which is based on a homogeneous and isotropic universe with a small cosmological constant and matter. These observations, also known as “cosmic anomalies” include unexpected Cosmic Microwave Background perturbations on large angular scales, large dipolar peculiar velocity flows of galaxies (“bulk flows”) and the measurement of inhomogenous values of the fine structure constant on cosmological scales (“alpha dipole”). The presence of the observational anomalies could either be a large statistical fluctuation in the context of LCDM or it could indicate a non-trivial departure from the cosmological principle on Hubble scales. Such a departure is very much constrained by cosmological observatins for matter. For dark energy however there are no significant observational constraints for Hubble scale inhomogeneities. In this brief review I discuss some of the theoretical models that can naturally lead to inhomogeneous dark energy, their observational constraints and their potential to explain the large scale cosmic anomalies.

Title: A Cosmology Using a Hubble-Scale Casimir Effect
Author: Mike E. McCulloch
Abstract: The visible mass of the observable universe agrees with that needed for a flat cosmos, and the reason for this is not known. It is shown that this can be explained by modeling the Hubble volume as a black hole that emits Hawking radiation, and only wavelengths of this radiation that fit exactly into the Hubble distance are allowed, since partial waves would allow an inference of what lies outside the horizon. This model is equivalent to a Hubble-scale Casimir effect. It predicts a minimum mass for the observable universe which is in agreement with the observed mass, and that the observable universe gains mass as it expands and was hotter in the past. It also predicts a suppression of variation on the largest cosmic scales, that agrees with the low-l cosmic microwave background anomaly seen by the Planck satellite.
