WMAP 5-year constraints on time variation of and in a detailed recombination scenario
Claudia G. Scóccola, Susana. J. Landau, Hector Vucetich
We study the role of fundamental constants in an updated recombination scenario. We focus on the time variation of the fine structure constant, and the electron mass in the early U…
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 electron mass in the early universe and the Barrow-Magueijo model
Claudia G. Scóccola, Mercedes E. Mosquera, Susana J. Landau +1
We put limits on the time variation of the electron mass in the early universe using observational primordial abundances of D, He4 and Li7, recent data from the Cosmic Microwave Ba…
