Reconstructing the evolution of dark energy with variations of fundamental parameters
N. J. Nunes, T. Dent, C. J. A. P. Martins +1
Under the assumption that the variations of parameters of nature and the current acceleration of the universe are related and governed by the evolution of a single scalar field, we…
Evolution of Hybrid Defect Networks
C. J. A. P. Martins
We apply a recently developed analytic model for the evolution of monopole networks to the case of monopoles attached to one string, usually known as hybrid networks. We discuss sc…
New Constraints on variations of the fine structure constant from CMB anisotropies
Eloisa Menegoni, Silvia Galli, James Bartlett +2
We demonstrate that recent measurements of Cosmic Microwave Background temperature and polarization anisotropy made by the ACBAR, QUAD and BICEP experiments substantially improve t…
An Observational Determination of the Proton to Electron Mass Ratio in the Early Universe
Rodger I. Thompson, Jill Bechtold, John H. Black +6
In an effort to resolve the discrepancy between two measurements of the fundamental constant mu, the proton to electron mass ratio, at early times in the universe we reanalyze the…
