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…

Detection of Surface Brightness Fluctuations in NGC 4373 Using the Hubble Space Telescope

M. A. Pahre, J. R. Mould, A. Dressler +1

Surface brightness fluctuations (SBF) have been detected for three elliptical galaxies-NGC 3379 in the Leo group, NGC 4406 in the Virgo cluster, and NGC 4373 in the Hydra-Centaurus…

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…
