Analytical solutions for two inhomogeneous cosmological models with energy flow and dynamical curvature
P. C. Stichel
Recently we have introduced a nonrelativistic cosmological model (NRCM) exhibiting a dynamical spatial curvature. For this model the present day cosmic acceleration is not attribut…
Dynamical curvature in a nonstandard cosmological model
Peter C. Stichel
We consider a nonrelativistic cosmological model introduced in [1] and derived as the nonrelativistic limit (or approximation at sub-Hubble scales) of a general relativistic model…
Anisotropic geodesic fluid in non-comoving spherical coordinates
Peter C. Stichel
We start with a recently introduced spherically symmetric geodesic fluid model (arXiv: 1601.07030) whose energy-momentum tensor in the comoving frame is dust-like with nontrivial e…
Cosmological model with dynamical curvature
Peter C. Stichel
The recently introduced relativistic Lagrangian darkon fluid model (EPJ C (2015) 75:9) is generalized to a self-gravitating, irrotational, pressure-less and stress free geodesic fl…
General relativistic, nonstandard model for the dark sector of the Universe
P. C. Stichel, W. J. Zakrzewski
We present a general relativistic version of the self-gravitating fluid model for the dark sector of the Universe (darkon fluid) introduced in Phys. Rev. 80 (2009) 083513 and exten…
Nonstandard approach to gravity for the dark sector of the Universe
P. C. Stichel, W. J. Zakrzewski
We summarize the present state of research on the darkon fuid as a model for the dark sector of the Universe. Nonrelativistic massless particles are introduced as a realization of…
