Abstract:
    By cross-matching the currently largest optical catalogue of galaxy
    clusters and the NVSS radio survey data base, we obtain a large
    complete sample of brightest cluster galaxies (BCGs) in the redshift
    range of 0.05<z<=0.45, which have radio emission and redshift
    information. We confirm that more powerful radio BCGs tend to be these
    optically very bright galaxies located in more relaxed clusters. We
    derived the radio luminosity functions of the largest sample of radio
    BCGs, and find that the functions depend on the optical luminosity of
    BCGs and the dynamic state of galaxy clusters. However, the radio
    luminosity function does not show significant evolution with redshift.

Description:
    Based on the largest optical catalogue of galaxy clusters of Wen and
    Han (2015, Cat. J/ApJ/807/178) and the largest radio survey data base
    of the NVSS (Condon et al., 1998, Cat. VIII/65) and FIRST (Helfand et
    al., Cat. VIII/92), we identified a large sample of 7138 radio-loud
    BCGs. More than half of radio BCGs host a AGN, and some of them show
    star-formation features.
