    Herschel-ATLAS/GAMA: What determines the far-infrared properties of radio galaxies?
    (2013) Virdee, J. S.; Hardcastle, M. J.; Rawlings, S.; Rigopoulou, D.; Mauch, T.; Jarvis, M. J.; Verma, A.; Smith, D. J. B.; Heywood, I.; White, S. V.; Baes, M.; Cooray, A.; de Zotti, G.; Eales, S.; Michalowski, M. J.; Bourne, N.; Dariush, A.; Dunne, L.; Hopwood, R.; Ibar, E.; Maddox, S.; Smith, M. W. L.; Valiante, E.
    We perform a stacking analysis of Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) data in order to obtain isothermal dust temperatures and rest-frame luminosities at 250 mu m (L-250), for a well-defined sample of 1599 radio sources over the H-ATLAS Phase 1/Galaxy and Mass Assembly (GAMA) area. The radio sample is generated using a combination of NRAO VLA Sky Survey data and K-band United Kingdom Infrared Telescope Deep Sky Survey-Large Area Survey data, over the redshift range 0.01 < z < 0.8. The far-infrared (FIR) properties of the sample are investigated as a function of 1.4-GHz luminosity, redshift, projected radio-source size and radio spectral index. In order to search for stellar-mass-dependent relations, we split the parent sample into those sources which are below and above 1.5 L-K*.
