Updated CMB constraints on Dark Matter annihilation cross-sections
Silvia Galli, Fabio Iocco, Gianfranco Bertone +1
The injection of secondary particles produced by Dark Matter (DM) annihilation at redshift 100<z<1000 affects the process of recombination, leaving an imprint on Cosmic Microwave B…
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…
Future weak lensing constraints in a dark coupled universe
Francesco De Bernardis, Matteo Martinelli, Alessandro Melchiorri +2
Coupled cosmologies can predict values for the cosmological parameters at low redshifts which may differ substantially from the parameters values within non-interacting cosmologies…
Limits on Dark Radiation, Early Dark Energy, and Relativistic Degrees of Freedom
Erminia Calabrese, Dragan Huterer, Eric V. Linder +2
Recent cosmological data analyses hint at the presence of an extra relativistic energy component in the early universe. This component is often parametrized as an excess of the eff…
CMB Neutrino Mass Bounds and Reionization
Maria Archidiacono, Asantha Cooray, Alessandro Melchiorri +1
Current cosmic microwave background (CMB) bounds on the sum of the neutrino masses assume a sudden reionization scenario described by a single parameter that determines the onset o…
Constraining Modified Gravity with Euclid
Matteo Martinelli, Erminia Calabrese, Francesco De Bernardis +3
Future proposed satellite missions as Euclid can offer the opportunity to test general relativity on cosmic scales through mapping of the galaxy weak lensing signal. In this paper…
