Future constraints on variations of the fine structure constant from combined CMB and weak lensing measurements
Matteo Martinelli, Eloisa Menegoni, Alessandro Melchiorri
We forecast the ability of future CMB and galaxy lensing surveys to constrain variations of the fine structure constant. We found that lensing data, as those expected from satellit…

The Fine Structure Constant and the CMB Damping Scale
Eloisa Menegoni, Maria Archidiacono, Erminia Calabrese +3
The recent measurements of the Cosmic Microwave Background anisotropies at arcminute angular scales performed by the ACT and SPT experiments are probing the damping regime of CMB f…
