Abstract

We investigate the 70μm far-infrared–radio correlation (FRC) of star-forming galaxies in the Extended Chandra Deep Field South (ECDFS) out toz>2.We use 70μmdata from the Far-Infrared Deep Extragalactic Legacy Survey (FIDEL), which comprises the most sensitive (∼0.8 mJy rms) and extensive far-infrared deep field observations using MIPS on the Spitzer Space Telescope, and 1.4 GHz radio data (∼8μJy beam−1 rms) from the Very Large Array. In order to quantify the evolution of the FRC, we use both survival analysis and stacking techniques,which we find give similar results.We also calculate the FRC using total infrared luminosity and rest-frame radio luminosity, qTIR, and find that qTIR is constant (within 0.22) over the redshift range 0–2.We see no evidence for evolution in the FRC at 70μm, which is surprising given the many factors that are expected to change this ratio at high redshifts.
