Despite their reputation as being "red and dead", the unique environmentinhabited by Brightest Cluster Galaxies (BCGs) can often lead to aself-regulated feedback cycle between radiatively cooling intracluster gas andstar formation and AGN activity in the BCG. However the prevalence of "active"BCGs, and details of the feedback involved, are still uncertain. We haveperformed an optical, UV and Mid-IR photometric analysis of the BCGs in 981clusters at 0.03 < z < 0.5, selected from the ROSAT All Sky Survey. UsingPan-STARRS PS1 3pi, GALEX and WISE survey data we look for BCGs withphotometric colours which deviate from that of the bulk population of passiveBCGs - indicative of AGN and/or star formation activity within the BCG. We findthat whilst the majority of BCGs are consistent with being passive, at least14% of our BCGs show a significant colour offset from passivity in at least onecolour index. And, where available, supplementary spectroscopy reveals themajority of these particular BCGs show strong optical emission lines. Oncomparing BCG "activity" with the X-ray luminosity of the host cluster, we findthat BCGs showing a colour offset are preferentially found in the more X-rayluminous clusters, indicative of the connection between BCG "activity" and theintracluster medium.
