ADC_Keywords: Galaxies, IR ; Radio continuum Keywords: galaxies: active - galaxies: elliptical and lenticular, cD - radio continuum: galaxies Abstract: We have measured the radio continuum emission of 396 early-type galaxies brighter than K=9, using 1.4GHz imagery from the NRAO Very Large Array Sky Survey, Green Bank 300ft Telescope, and 64m Parkes Radio Telescope. For MK←24 early-type galaxies, the distribution of radio powers at fixed absolute magnitude spans four orders of magnitude and the median radio power is proportional to K-band luminosity to the power 2.78±0.16. The measured flux densities of MK←25.5 early-type galaxies are greater than zero in all cases. It is thus highly likely that the most massive galaxies always host an active galactic nucleus or have recently undergone star formation. Description: Our principal radio imaging is the 1.4GHz NVSS (Condon et al. 1998, Cat. VIII/65), which has an angular resolution of 45" and an rms noise of ∼0.45mJy. We also measure flux densities using lower resolution (∼12') imaging from the 300ft Green Bank and the 64m Parkes radio telescopes (Condon & Broderick 1985-86, Cat. VIII/6; Barnes et al. 2001MNRAS.322..486B, see Cat. VIII/73; M. Calabretta 2011, in preparation). File Summary:
