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.
