On Radiative Fluids in Anisotropic Spacetimes
Dmitry Shogin, Per Amund Amundsen
We apply the second-order Israel-Stewart theory of relativistic fluid- and thermodynamics to a physically realistic model of a radiative fluid in a simple anisotropic cosmological…
Local equilibrium solutions in simple anisotropic cosmological models, as described by relativistic fluid dynamics
Dmitry Shogin, Per Amund Amundsen
We test the physical relevance of the full and the truncated versions of the Israel-Stewart theory of irreversible thermodynamics in a cosmological setting. Using a dynamical syste…
On the viability of the truncated Israel-Stewart theory in cosmology
Dmitry Shogin, Per Amund Amundsen, Sigbjørn Hervik
We apply the causal Israel-Stewart theory of irreversible thermodynamics to model the matter content of the universe as a dissipative fluid with bulk and shear viscosity. Along wit…
The late-time behaviour of tilted Bianchi type VIII universes in presence of diffusion
Dmitry Shogin, Sigbjørn Hervik
We apply the dynamical systems approach to ever-expanding Bianchi type VIII cosmologies filled with a tilted -fluid undergoing velocity diffusion on a scalar field. We determine…
Dynamics of tilted Bianchi models of types III, IV, V in presence of diffusion
Dmitry Shogin, Sigbjørn Hervik
We investigate the three types of class B Bianchi cosmologies filled with a tilted perfect fluid undergoing velocity diffusion in a scalar field background. We consider the two mos…
Evolution of a Simple Inhomogeneous Anisotropic Cosmological Model with Diffusion
Dmitry Shogin, Sigbjorn Hervik
We investigate a simple inhomogeneous anisotropic cosmology (plane symmetric model) filled with a tilted perfect fluid undergoing velocity diffusion on a scalar field. Consid…
