We search for ongoing major dry-mergers in a well selected sample of local Brightest Cluster Galaxies ( BCGs ) from the C4 cluster catalogue . 18 out of 515 early-type BCGs with redshift between 0.03 and 0.12 are found to be in major dry-mergers , which are selected as pairs ( or triples ) with r -band magnitude difference \delta m _ { r } < 1.5 and projected separation r _ { p } < 30 kpc , and showing signatures of interaction in the form of significant asymmetry in residual images . We find that the fraction of BCGs in major dry-mergers increases with the richness of the clusters , consistent with the fact that richer clusters usually have more massive ( or luminous ) BCGs . We estimate that present-day early-type BCGs may have experienced on average \sim 0.6 ( t _ { merge } / 0.3 { Gyr } ) ^ { -1 } major dry-mergers and through this process increases their luminosity ( mass ) by 15 \% ( t _ { merge } / 0.3 { Gyr } ) ^ { -1 } ( f _ { mass } / 0.5 ) on average since z = 0.7 , where t _ { merge } is the merging timescale and f _ { mass } is the mean mass fraction of companion galaxies added to the central ones . We also find that major dry-mergers do not seem to elevate radio activities in BCGs . Our study shows that major dry-mergers involving BCGs in clusters of galaxies are not rare in the local Universe , and they are an important channel for the formation and evolution of BCGs .
