A Comparison of Ultraviolet, Optical, and X-Ray Imagery of Selected Fields in the Cygnus Loop
Charles W. Danforth, Robert H. Cornett, N. A. Levenson +2
During the Astro-1 and Astro-2 Space Shuttle missions in 1990 and 1995, far ultraviolet (FUV) images of five 40' diameter fields around the rim of the Cygnus Loop supernova remnant…
Star Formation Triggering Mechanisms in Dwarf Galaxies: The Far-Ultraviolet, H-alpha, and HI Morphology of Holmberg II
S. G. Stewart, M. N. Fanelli, G. G. Byrd +8
Far-UV (FUV), H-alpha, and HI observations of dwarf galaxy Holmberg II are used to trace the interaction between sites of massive star formation and the neutral and ionized compone…
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…
Ultraviolet Imaging Telescope (UIT) Observations of the SMC
Robert H. Cornett, Theodore P. Stecher, the UIT Science Team
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 SMC's Bar…
