A critical assessment of some inhomogeneous pressure Stephani models
Adam Balcerzak, Mariusz P. Dabrowski, Tomasz Denkiewicz +2
We consider spherically symmetric inhomogeneous pressure Stephani universes, the center of symmetry being our location. The main feature of these models is that comoving observers…
Constraining decaying dark energy density models with the CMB temperature-redshift relation
Philippe Jetzer, Crescenzo Tortora
We discuss the thermodynamic and dynamical properties of a variable dark energy model with density scaling as , z being the redshift. These models lead to th…
Limits on decaying dark energy density models from the CMB temperature-redshift relation
Philippe Jetzer, Denis Puy, Monique Signore +1
The nature of the dark energy is still a mystery and several models have been proposed to explain it. Here we consider a phenomenological model for dark energy decay into photons a…
Chemistry of heavy elements in the Dark Ages
P. Vonlanthen, T. Rauscher, C. Winteler +3
Primordial molecules were formed during the Dark Ages, i.e. the time between recombination and reionization in the early Universe. The purpose of this article is to analyze the for…
Molecular fluorine chemistry in the early Universe
Denis Puy, Victor Dubrovich, Anton Lipovka +2
Some models of Big Bang nucleosynthesis suggest that very high baryon density regions were formed in the early Universe, and generated the production of heavy elements other than l…
Possible flakes of molecular hydrogen in the early Universe
D. Pfenniger, D. Puy
The thermochemistry of H2 and HD in non-collapsed, non-reionized primordial gas up to the end of the dark age is investigated with recent radiation-matter and chemical reaction rat…
