We use stacking techniques to probe the correlation for galaxies that are upto 3 orders of magnitude fainter than those directly detected in FIR bands. We find that the tight radio-FIR correlation holds for these galaxies at all redshifts. Within the uncertainties of our measurement, there is no evolution of the correlation with redshift. However, we do find that the slope of the correlation is systematically different from unity and is steeper. The characteristic dust temperature evolves linearly with redshift. Some implications of these measurements to existing models will be discussed. |
