Quantifying the Faint Structure of Galaxies: The Late-type Spiral NGC 2403
Mike K. Barker, Annette M. N. Ferguson, Mike J. Irwin +2
Ground-based surveys have mapped the stellar outskirts of Local Group galaxies in unprecedented detail, but extending this work to other galaxies is necessary to overcome stochasti…
The Star Formation History in The Far Outer Disc of M33
M. K. Barker, A. M. N. Ferguson, A. A. Cole +5
The outer regions of disc galaxies are becoming increasingly recognized as key testing sites for models of disc assembly and evolution. Important issues are the epoch at which the…
Resolving the Stellar Outskirts of M81: Evidence for a Faint, Extended Structural Component
M. K. Barker, A. M. N. Ferguson, M. Irwin +2
We present a wide field census of resolved stellar populations in the northern half of M81, conducted with Suprime-Cam on the 8-m Subaru telescope and covering an area ~ 0.3 square…
The Discovery of Remote Globular Clusters in M33
A. Huxor, A. M. N. Ferguson, M. K. Barker +5
We present the discovery of four remote star clusters in M33, one of which is of an extended nature. Three of the clusters were discovered using survey data from the Isaac Newton T…
Newly Identified Star Clusters in M33. I. Integrated Photometry and Color-Magnitude Diagrams
Ata Sarajedini, M. K. Barker, Doug Geisler +2
We present integrated photometry and color-magnitude diagrams (CMDs) for 24 star clusters in M33, of which 12 were previously uncataloged. These results are based on Advanced Camer…
RR Lyrae Variables in M33. I. Evidence For a Field Halo Population
Ata Sarajedini, M. K. Barker, Doug Geisler +2
We present observations of RR Lyrae variables in the Local Group late-type spiral galaxy M33. Using the Advanced Camera for Surveys on the Hubble Space Telescope, we have identifie…
