The Extended Disk Galaxy Exploration Science Survey: Description and
  Surface Brightness Profile Properties
  The survey description and near-infrared properties for 92 galaxies are
presented for the Extended Disc Galaxy Exploration Science (EDGES) Survey,
along with an investigation into the properties of the stellar halos of these
galaxies. EDGES is a Spitzer Space Telescope Warm Mission program designed to
reach the surface brightness limit ($\sim$0.5 kJy sr$^{-1}$ or 29 AB mag
arcsec$^{-2}$) of the Infrared Array Camera (IRAC) 3.6 and 4.5 $\mu$m bands for
a wide range of galaxy types found within the local volume. The surface
brightness profiles exhibit a large range in disc scalelength, with breaks more
frequently seen than in previous studies, owing in large part to the extremely
deep near-infrared imaging. A number of these surface brightness profile breaks
may be due to stellar halos, up to 7 galaxies out of the full sample of 92
galaxies, and we explore these implications in relation to current cosmological
models. We also report the discovery of a new tidal stream near NGC 3953.
