Absorption features in sub-TeV gamma-ray spectra of BL Lac objects
L. Foffano, V. Vittorini, M. Tavani +1
The production site of gamma rays in blazars is closely related to their interaction with the photon fields surrounding the active galactic nucleus. In this paper, we discuss an in…
Constraints on a scale-dependent bias from galaxy clustering
L. Amendola, E. Menegoni, C. Di Porto +2
We forecast the future constraints on scale-dependent parametrizations of galaxy bias and their impact on the estimate of cosmological parameters from the power spectrum of galaxie…
Planck intermediate results. XXIV. Constraints on variation of fundamental constants
P. A. R. Ade, N. Aghanim, M. Arnaud +166
Any variation of the fundamental physical constants, and more particularly of the fine structure constant, , or of the mass of the electron, , would affect the recombinatio…
Planck 2013 results. XVI. Cosmological parameters
Planck Collaboration, P. A. R. Ade, N. Aghanim +261
We present the first results based on Planck measurements of the CMB temperature and lensing-potential power spectra. The Planck spectra at high multipoles are extremely well descr…
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…
Constraining Variations in the Fine Structure Constant in the presence of Early Dark Energy
Erminia Calabrese, Eloisa Menegoni, C. J. A. P. Martins +2
We discuss present and future cosmological constraints on variations of the fine structure constant induced by an early dark energy component having the simplest allowed (linea…
Varying couplings in the early universe: correlated variations of and
C. J. A. P. Martins, Eloisa Menegoni, Silvia Galli +2
The Cosmic Microwave Background anisotropies provide a unique opportunity to constrain simultaneous variations of the fine-structure constant and Newton's gravitational constan…
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…
