The adiabatic evolution of the temperature of the cosmic microwave background (CMB) is a key prediction of standard cosmology. We study deviations from the expected adiabatic evolution of the CMB temperature of the form T(z) = T_0(1 + z)^(1 − α) using measurements of the spectrum of the Sunyaevâ€...
