Ultradeep Imaging of Nearby Dwarf Irregular Galaxies: Young Objects in the Far Outer Disk

Ultradeep UBVI imaging of 10 nearby (≤7.8 Mpc) noninteracting dwarf irregular galaxies are used to examine their far outer stellar disks. The annulus between 26 mag arcsec ^−2 and 29 mag arcsec ^−2 in the V band is what we define as the far outer disk and is our focus here. Photometry of distinct ob...
