Disentangling the assembly of the central and diffuse stellar components in galaxy clusters through dynamical friction and tidal stripping
Frazer R. Pearce, Steven P. Bamford, Garreth Martin +7
In galaxy clusters, it is common to conceptually distinguish the central, brightest cluster galaxy (BCG) from the more diffuse intracluster light (ICL). So far, however, this disti…
