Variation of the fine structure constant and the electron mass at early Universe
Claudia G. Scóccola
In this thesis, we focus on the study of the variation of the electron mass , and the fine structure constant , at different cosmic times. We analyze the details of the rec…
Observing the Evolution of the Universe
James Aguirre, Alexandre Amblard, Amjad Ashoorioon +172
How did the universe evolve? The fine angular scale (l>1000) temperature and polarization anisotropies in the CMB are a Rosetta stone for understanding the evolution of the univers…
The Origin of the Universe as Revealed Through the Polarization of the Cosmic Microwave Background
S. Dodelson, R. Easther, S. Hanany +61
Modern cosmology has sharpened questions posed for millennia about the origin of our cosmic habitat. The age-old questions have been transformed into two pressing issues primed for…
Early Universe Constraints on Time Variation of Fundamental Constants
Susana J. Landau, Mercedes E. Mosquera, Claudia G. Scoccola +1
We study the time variation of fundamental constants in the early Universe. Using data from primordial light nuclei abundances, CMB and the 2dFGRS power spectrum, we put constraint…
Time variation of the fine structure constant in the early universe and the Bekenstein model
Mercedes E. Mosquera, Claudia G. Scoccola, Susana J. Landau +1
We calculate bounds on the variation of the fine structure constant at the time of primordial nucleosynthesis and at the time of neutral hydrogen formation. We use these bounds and…
The formation and evolution of hydrogen-deficient post-AGB white dwarfs: the emerging chemical profile and the expectations for the PG1159-DB-DQ evolutionary connection
L. G. Althaus, A. M. Serenelli, J. A. Panei +3
This paper is designed to explore the formation and evolution of hydrogen-deficient post-AGB white dwarfs. To this end, we compute the complete evolution of an initially 2.7 M_sun…
