The local radio luminosity function of galaxies at 843 MHz

On the local radio luminosity function of galaxies

We cross-correlate the galaxies brighter than mB = 18 in the Virgo cluster with the radio sources in the NVSS survey (1.4 GHz), resulting in 180 radio-optical identifications. We determine the radio luminosity function of the Virgo galaxies, separately for the earlyand late-types. Late-type galaxies develop radio sources with a probability proportional to their optical luminosity. In fact their...

On the local radio luminosity function of galaxies. II: environmental dependences among late-type galaxies

Using new extensive radio continuum surveys at 1.4 GHz (FIRST and NVSS), we derive the distribution of the radio/optical and radio/NIR luminosity (RLF) of late-type (Sa-Irr) galaxies (mp < 15.7) in 5 nearby clusters of galaxies: A262, Cancer, A1367, Coma and Virgo. With the aim of discussing possible environmental dependences of the radio properties, we compare these results with those obtained...

The Radio Luminosity Function of the NEP Distant Cluster Radio Galaxies

A complete sample of 18 X-ray selected clusters of galaxies belonging to the ROSAT North Ecliptic Pole (NEP) survey has been observed with the Very Large Array at 1.4 GHz. These are the most distant clusters in the X-ray survey with redshift in the range 0.3 < z < 0.8. Seventy-nine radio sources are detected within half an Abell radius with an observed peak brightness > 0.17 mJy beam−1, except ...
