Cosmology models with Ω_M-dependent cosmological constant [PDF]
Gen.Rel.Grav. 35 (2003) 1007-1016, 2002 We investigate the evolution of the scale factor in a cosmological model in which the cosmological constant is given by the scalar arisen by the contraction of the stress-energy tensor.

, 2006 Brane-world models, where observers are restricted to a brane in a higher-dimensional spacetime, offer a novel perspective on cosmology. I discuss some approaches to cosmology in extra dimensions and some interesting aspects of gravity and cosmology in ...

Testing general relativity in cosmology [PDF]
Living Reviews in Relativity, 2018 We review recent developments and results in testing general relativity (GR) at cosmological scales. The subject has witnessed rapid growth during the last two decades with the aim of addressing the question of cosmic acceleration and the dark energy ...

When misinterpreting the Bible becomes a habit
HTS Teologiese Studies/Theological Studies, 2018 Ancient Near Eastern (ANE) texts should be interpreted against the background of the magico-mythical cosmology of their time, and the Bible is no exception.

Parity-violation in bouncing cosmology
Journal of High Energy Physics, 2023 We investigate the possibility of the enhancement of parity-violation signal in bouncing cosmology. Specifically, we are interested in deciding which phase should generate the most significant parity-violation signals.

New Journal of Physics, 2004 I review the basics of neutrino cosmology, from the question of neutrino decoupling and the presence of sterile neutrinos to the effects of neutrinos on the cosmic microwave background and large scale structure. Particular emphasis is put on cosmological neutrino mass measurements, both the present bounds and the future prospects.

Chaos and Order: Contemporary Cosmology and Myth
Etnoantropološki Problemi, 2020 The paper offers a definition of cosmology and its connections with mythology, and presents contemporary theories as a secular mythical narrative suitable for anthropological analysis. The paper is dedicated to emphasizing the folklore characteristics of

Averaging in cosmological models using scalars [PDF]
Class.Quant.Grav.27:245017,2010, 2009 The averaging problem in cosmology is of considerable importance for the correct interpretation of cosmological data. A rigorous mathematical definition of averaging in a cosmological model is necessary. In general, a spacetime is completely characterized by its scalar curvature invariants, and this suggests a particular spacetime averaging scheme ...
