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…
Anti-lensing: the bright side of voids
Krzysztof Bolejko, Chris Clarkson, Roy Maartens +3
More than half of the volume of our Universe is occupied by cosmic voids. The lensing magnification effect from those under-dense regions is generally thought to give a small dimmi…
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…
Ricci focusing, shearing, and the expansion rate in an almost homogeneous Universe
Krzysztof Bolejko, Pedro G. Ferreira
The Universe is inhomogeneous, and yet it seems to be incredibly well-characterised by a homogeneous relativistic model. One of the current challenges is to accurately characterise…
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…
