Deep HST Imaging of Sextans A I. The Spatially Resolved Recent Star Formation History
R. C. Dohm-Palmer, E. D. Skillman, M. Mateo +5
We have measured stellar photometry from deep Cycle 7 Hubble Space Telescope/WFPC2 imaging of the dwarf irregular galaxy Sextans A. The imaging was taken in three filters: F555W ($…
The Star Formation History of the Large Magellanic Cloud
Tammy A. Smecker-Hane, Andrew A. Cole, John S. Gallagher +1
Using WFPC2 aboard the Hubble Space Telescope, we have created deep color-magnitude diagrams in the V and I passbands for approximately 100,000 stars in a field at the center of th…
The 2MASS Color-Magnitude Diagram of the Center of the Sagittarius Dwarf Galaxy: Photometric Measurements of a Surprisingly High Mean Metallicity
A. A. Cole
We present the Two Micron All Sky Survey (2MASS) (J-K, K) color-magnitude diagram for the region within 1 degree of the center of the Sagittarius dwarf spheroidal galaxy. Using the…
Using the Ca II Triplet to Trace Abundance Variations in Individual Red Giant Branch stars in Three Nearby Galaxies
Eline Tolstoy, Michael J. Irwin, Andrew A. Cole +3
Spectroscopic abundance determinations for stars spanning a Hubble time in age are necessary in order to unambiguously determine the evolutionary histories of galaxies. Using FORS1…
