SUMMARY:The Peripheries of Nearby Galaxies: Dim but not Dull
DESCRIPTION:The Peripheries of Nearby Galaxies: Dim but not Dull\nProf. Ann
 ette Ferguson\n\nEvidence is mounting for the presence of complex low surf
 ace brightness structures in the outer regions of galaxies. While the most
  spectacular examples are provided by systems hosting coherent debris stre
 ams, the most common examples may be extremely diffuse stellar envelopes. 
 Wide-field imagers on large telescopes are allowing us to quantitatively e
 xplore the resolved stellar populations in these components within and wel
 l beyond the Local Group. I will highlight some recent  results from 
 our work and discuss the insight these outer structures provide on underst
 anding massive  galaxy assembly.  I will also discuss how we are
  using deep HST studies of M31's outer regions to probe its evolutionary h
 istory in unprecedented detail.
