J/MNRAS/460/3669    Brightest cluster galaxies Radio luminosity    (Yuan+, 2016)

Radio luminosity function of brightest cluster galaxies. Yuan Z.S., Han J.L., Wen Z.L. <Mon. Not. R. Astron. Soc., 460, 3669-3678 (2016)> =2016MNRAS.460.3669Y (SIMBAD/NED BibCode)
ADC_Keywords: Clusters, galaxy ; Radio sources Keywords: galaxies: clusters: general - galaxies: luminosity function, mass function 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. File Summary:
