Square Kilometre Array and Cosmic Microwave Background spectral distortions |

Abstract |
The current limits on CMB spectral distortions (up to cm wavelengths) and the constraints on energy dissipation processes in the plasma has been recently reconsidered in the context of new CMB space missions (such as PIXIE and PRISM). At higher wavelengths, Bose-Einstein like and free-free distortions as well as particular spectral shapes are theoretically predicted in a wide set of astrophysical and cosmological processes. SKA continuum surveys will represent a great opportunity for an accurate determination of source number counts down to very faint fluxes, significantly helping the solution of one fundamental problem of the future generation of CMB spectrum experiments at long wavelengths. |
