WebWe use deep surface photometry of the giant elliptical M49 (NGC 4472), obtained as part of our survey for diffuse light in the Virgo Cluster, to study the stellar populations in its outer halo. Our data trace M49's stellar halo out to ~100 kpc (7r e ), where we find that the shallow color gradient seen in the inner regions becomes dramatically steeper.
