Journal ArticleDOI
The emergent universe: an explicit construction
TL;DR: In this article, the authors provide a realization of a singularity-free inflationary universe in the form of a simple cosmological model dominated at early times by a single minimally coupled scalar field with a physically based potential.
Journal ArticleDOI
Primordial magnetogenesis
TL;DR: In this paper, the authors review the question of primordial magnetism and consider the limits set on their strength by the current observational data and also discuss how future observations could be used to decide whether the large-scale magnetic fields we see in the universe today are truly primordial or not.
Journal ArticleDOI
Relativistic cosmology and large-scale structure
TL;DR: In this article, a review of general-relativistic dynamics and perturbations of the standard cosmological model, the Friedmann-Lemaitre universe, and how these can explain and predict the properties of the observable universe is presented.
Journal ArticleDOI
The First Magnetic Fields
Lawrence M. Widrow,Dongsu Ryu,Dominik R. G. Schleicher,Kandaswamy Subramanian,Christos G. Tsagas,Rudolf A. Treumann +5 more
TL;DR: In this paper, the authors review current ideas on the origin of galactic and extragalactic magnetic fields and examine mechanisms for the generation of magnetic fields that operate prior during inflation and during subsequent phase transitions such as electroweak symmetry breaking and the quark-hadron phase transition.
Journal ArticleDOI
Cosmology with inhomogeneous magnetic fields
TL;DR: In this paper, the effects of magnetic fields on the expansion dynamics and the growth of density inhomogeneities in a spatially homogeneous and isotropic universe were investigated.
