Constraints on the CMB temperature redshift dependence from SZ and distance measurements

A. Avgoustidis, G. Luzzi, C. J. A. P. Martins +1

The relation between redshift and the CMB temperature, $T_{CMB}(z)=T_0(1+z)$ is a key prediction of standard cosmology, but is violated in many non-standard models. Constraining po…
