Deep near-infrared images recorded with NICI on Gemini South are used to investigate the evolved stellar content in the outer southeast quadrant of the spiral galaxy M83. A diffuse population of asymptotic giant branch (AGB) stars is detected, indicating that there are stars outside of the previously identified young and intermediate age star clusters in the outer disk. The brightest AGB stars have M K ≥ –8, and the AGB luminosity function (LF) is well matched by model LFs that assume ages ≤1… Expand
Shaken, Not Stirred: The Disrupted Disk of the Starburst Galaxy NGC 253
Near-infrared images obtained with WIRCam on the Canada-France-Hawaii Telescope are used to investigate the recent history of the nearby Sculptor Group spiral NGC 253, which is one of the nearestExpand
Stellar Populations in the Outer Disk and Halo of the Spiral Galaxy M101
We use deep Hubble Space Telescope imaging in the outskirts of the nearby spiral M101 to study stellar populations in the galaxy's outer disk and halo. Our ACS field lies 17.6 arcmin (36 kpc) fromExpand
A pilot study using deep infrared imaging to constrain the star formation history of the XUV stellar populations in NGC 4625
In a LCDM universe, disk galaxies' outer regions are the last to form. Characterizing their contents is critical for understanding the ongoing process of disk formation, but observing outer diskExpand
Resolved Near-Infrared Stellar Populations in Nearby Galaxies

The Red and Featureless Outer Disks of Nearby Spiral Galaxies
We present results from deep, wide-field surface photometry of three nearby (D=4--7 Mpc) spiral galaxies: M94 (NGC 4736), M64 (NGC 4826), and M106 (NGC 4258). Our imaging reaches limiting surfaceExpand
