NED Abstract

Copyright by Royal Astronomical Society. 2007MNRAS.379.1042V The far-infrared-radio relationship at high and low redshift Catherine Vlahakis, Stephen Eales and Loretta Dunne Abstract. We use the results of the SCUBA Local Universe Galaxy Survey, a submillimetre (submm) survey of galaxies in the nearby Universe, to investigate the relationship between the far-infrared (FIR)-submm and radio emission of galaxies at both low and high redshift. At low redshift we show that the correlation between radio and FIR emission is much stronger than the correlation between radio and submm emission, which is evidence that massive stars are the source of both the FIR and radio emission. At high redshift we show that the submm sources detected by SCUBA are brighter sources of radio emission than are predicted from the properties of galaxies in the local Universe. We discuss possible reasons for the cosmic evolution of the relationship between radio and FIR emission. Key words: surveys, galaxies: distances and redshifts, galaxies: ISM, radio continuum: galaxies
