Observations and Implications of the Star Formation History of the LMC
J. A. Holtzman, J. S. Gallagher, A. A. Cole +3
We present derivations of star formation histories based on color-magnitude diagrams of three fields in the LMC from HST/WFPC2 observations. A significant component of stars older…
WFPC2 Observations of Compact Star Cluster Nuclei in Low Luminosity Spiral Galaxies
Lynn D. Matthews, John S. Gallagher, III +16
We have used the Wide Field Planetary Camera 2 aboard the Hubble Space Telescope to image the compact star cluster nuclei of the nearby, late-type, low-luminosity spiral galaxies N…
Stellar Populations in Three Outer Fields of the LMC
Marla C. Geha, Jon A. Holtzman, Jeremy R. Mould +16
We present HST photometry for three fields in the outer disk of the LMC extending approximately four magnitudes below the faintest main sequence turnoff. We cannot detect any stron…
Hubble Space Telescope Observations of the Draco Dwarf Spheroidal
Carl. J. Grillmair, Jeremy R. Mould, Jon A. Holtzman +15
We present an F606W-F814W color-magnitude diagram for the Draco dwarf spheroidal galaxy based on Hubble Space Telescope WFPC2 images. The luminosity function is well-sampled to 3 m…
WFPC2 Observations of the Cooling Flow Elliptical in Abell 1795
Jason Pinkney, Jon Holtzman, Chris Garasi +3
We present WFPC2 images of the core of the cooling flow cD galaxy in Abell 1795. An irregular, asymmetric dust lane extends 7 \h75 kpc in projection to the north-northwest. The dus…
