Measuring $α$ in the Early Universe: CMB Polarization, Reionization and the Fisher Matrix Analysis

G. Rocha, R. Trotta, C. J. A. P. Martins +4

We present a detailed analysis of present and future Cosmic Microwave Background constraints of the value of the fine-structure constant, $α$ . We carry out a more detailed analysis…

Measuring $α$ in the Early Universe: CMB Temperature, Large-Scale Structure and Fisher Matrix Analysis

C. J. A. P. Martins, A. Melchiorri, R. Trotta +4

We extend our recent work on the effects of a time-varying fine-structure constant $α$ in the cosmic microwave background, by providing a thorough analysis of the degeneracies betw…
