2011ApJ...731L..41B The Ubiquitous Radio Continuum Emission from the Most Massive Early-type Galaxies Brown, Michael J. I.; Jannuzi, Buell T.; Floyd, David J. E.; Mould, Jeremy R. Abstract. We have measured the radio continuum emission of 396 early-type galaxies brighter than K = 9, using 1.4 GHz imagery from the NRAO Very Large Array Sky Survey, Green Bank 300 ft Telescope, and 64 m Parkes Radio Telescope. For M_K_ < -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 M_K_ < -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. Key words: galaxies: active, galaxies: elliptical and lenticular, cD, radio continuum: galaxies
