Starburst Anatomy: Stellar and Nebular Properties of Nearby Giant HII Regions
William H. Waller
Resolution of nearby giant HII regions into their stellar and nebular constituents provides fundamental insights for interpreting more distant and powerful starburst activity. The…
Survey of Fine-Scale Structure in the Far-Infrared Milky Way
William H. Waller, Frank Varosi, Francois Boulanger +1
Using the IRAS Infrared Sky Survey Atlas, we have made 60 x 60 deg mosaics of the far-infrared emission in the Milky Way. By applying a median normalizing spatial filter, we were a…
Ultraviolet Imaging Telescope (UIT) Observations of the Small Magellanic Cloud
Robert H. Cornett, Michael R. Greason, Jesse K. Hill +9
A mosaic of four UIT far-UV (FUV; 1620A) images, which covers most of the SMC bar, is presented, with derived stellar and HII region photometry. The UV morphology of the Bar shows…
The UIT Survey of the Ultraviolet Sky Background
William H. Waller, Theodore P. Stecher, Ultraviolet Imaging Telescope Science Team
When viewed from above the Earth's atmosphere, the nighttime ultraviolet sky background is profoundly dark - up to 100 times fainter than the equivalent visible background as measu…
