  • We use deep V-band surface photometry of five of the brightest elliptical galaxies in the Virgo Cluster to search for diffuse tidal streams, shells, and plumes in their outer halos (r>50 kpc). We fit and subtract elliptical isophotal models from the galaxy images to reveal a variety of substructure, with surface brightnesses in the range {mu} {sub V} = 26-29 mag arcsec{sup -2}. M49 possesses an extended, interleaved shell system reminiscent of the radial accretion of a satellite companion… CONTINUE READING
