Abstract:
    Radio observations were used to detect the "active" galaxy population
    within rich clusters of galaxies in a nonbiased manner that is not
    plagued by dust extinction or the K-correction. We present wide-field
    radio, optical (imaging and spectroscopy), and ROSAT All-Sky Survey
    (RASS, Cat. IX/10) X-ray data for a sample of 30 very rich Abell
    (R≥2) cluster with z≤0.25. The VLA radio data samples the ultrafaint
    radio (L(1.4GHz)≥2x1022W/Hz) galaxy population within these
    extremely rich clusters for galaxies with RMAG≤-21. This is the
    largest sample of low-luminosity 20 cm radio galaxies within rich
    Abell clusters collected to date.
