Cosmic Birefringence Test of the Hubble Tension
Ludovico M. Capparelli, Robert R. Caldwell, Alessandro Melchiorri
An early dark energy component consisting of a cosmic pseudo Nambu-Goldstone boson has been recently proposed to resolve the Hubble tension -- the four-sigma discrepancy between pr…
The impact of theoretical assumptions in the determination of the neutrino effective number from future CMB measurements
Ludovico Capparelli, Eleonora Di Valentino, Alessandro Melchiorri +1
One of the major goals of future Cosmic Microwave Background measurements is the accurate determination of the effective number of neutrinos . Reaching an experimental…
A note on polarized light from Magnetars
L. M. Capparelli, A. Damiano, L. Maiani +1
In a recent paper it is claimed that vacuum birefringence has been experimentally observed for the first time by measuring the degree of polarization of visible light from a Magnet…
Axion-like particle searches with sub-THz photons
L. Capparelli, G. Cavoto, J. Ferretti +3
We propose a variation, based on very low energy and extremely intense photon sources, on the well established technique of Light-Shining-through-Wall (LSW) experiments for axion-l…
Directional Dark Matter Searches with Carbon Nanotubes
L. M. Capparelli, G. Cavoto, D. Mazzilli +1
A new solution to the problem of dark matter directional detection might come from the use of large arrays of aligned carbon nanotubes. We calculate the expected rate of carbon ion…
