Ultraviolet and Optical Observations of OB Associations and Field Stars in the Southwest Region of the Large Magellanic Cloud
Joel Wm. Parker, Dennis Zaritsky, Theodore P. Stecher +2
Using photometry from the Ultraviolet Imaging Telescope (UIT) and photometry and spectroscopy from three ground-based optical datasets we have analyzed the stellar content of OB as…
The Morphologies of the Small Magellanic Cloud
Dennis Zaritsky, Jason Harris, Eva K. Grebel +1
We compare the distribution of stars of different spectral types, and hence mean age, within the central SMC and find that the asymmetric structures are almost exclusively composed…
HST Images of Stephan's Quintet: Star Cluster Candidates in a Compact Group Environment
S. C. Gallagher, S. D. Hunsberger, J. C. Charlton +1
We present HST WFPC2 images of Stephan's Quintet which encompass three interacting galaxies and their associated tidal features. These deep, three-color (B, V, I) images indicate r…
Measuring the Diffuse Optical Light in Abell 1651
Anthony H. Gonzalez, Ann I. Zabludoff, Dennis Zaritsky +1
Using drift scan data, a new approach to determining surface brightness profiles, and techniques for detecting low surface brightness signals, we fit the light profile of the brigh…
