Exact inhomogeneous models and the drift of light rays induced by nonsymmetric flow of the cosmic medium
Andrzej Krasiński, Krzysztof Bolejko
After introducing the Szekeres and Lema\^ıtre--Tolman cosmological models, the real-time cosmology program is briefly mentioned. Then, a few widespread misconceptions about the cos…
Geometry of the quasi-hyperbolic Szekeres models
Andrzej Krasiński, Krzysztof Bolejko
Geometric properties of the quasi-hyperbolic Szekeres models are discussed and related to the quasi-spherical Szekeres models. Typical examples of shapes of various classes of 2-di…
Repeatable light paths in the conformally flat cosmological models
Andrzej Krasiński
This is a supplement to an earlier paper (PRD 84, 023510 (2011)), where those shearfree normal cosmological models were identified, in which all light rays have repeatable paths. A…
Apparent horizons in the quasi-spherical Szekeres models
Andrzej Krasiński, Krzysztof Bolejko
The notion of an apparent horizon (AH) in a collapsing object can be carried over from the Lema\^ıtre -- Tolman (L--T) to the quasispherical Szekeres models in three ways: 1. Liter…
