2005ApJ...631L..41M Diffuse Light in the Virgo Cluster Mihos, J. Christopher; Harding, Paul; Feldmeier, John; Morrison, Heather Abstract. We present deep optical imaging of the inner ~1.5d x 1.5d of the Virgo Cluster to search for diffuse intracluster light (ICL). Our image reaches a 1 {sigma} depth of {mu}_V_=28.5 mag arcsec^-2^, which is 1.5 mag arcsec^-2^ deeper than previous surveys, and reveals an intricate web of diffuse ICL. We see several long (>100 kpc) tidal streamers, as well as a myriad of smaller scale tidal tails and bridges between galaxies. The diffuse halo of M87 is traced out to nearly 200 kpc, appearing very irregular on these scales, while significant diffuse light is also detected around the M84/M86 pair. Several galaxies in the core are embedded in common envelopes, suggesting they are true physical subgroups. The complex substructure of Virgo's diffuse ICL reflects the hierarchical nature of cluster assembly, rather than being the product of smooth accretion around a central galaxy.
