Confirmation of a Substantial Discrepancy between Radio and UV–IR Measures of the Star Formation Rate Density at 0.2 < z < 1.3

We present the initial sample of redshifts for 3,839 galaxies in the MeerKAT DEEP2 field – the deepest ∼1.4 GHz radio field yet observed. Using a spectrophotometric technique combining coarse optical spectra with broadband photometry, we obtain redshifts with σ_z ≤ 0.01(1+z). The resulting radio luminosity functions between 0.2更多
