Classification and Characterization of Objects from GALEX and SDSS surveys
Luciana Bianchi, M. Seibert, W. Zheng +22
We use the GALEX (Galaxy Evolution Explorer) Medium Imaging Survey (MIS) and All-Sky Imaging Survey (AIS) data available in the first internal release, matched to the SDSS catalogs…
Radio Detections of Ultraluminous X-ray Sources
Neal A. Miller, Susan G. Neff, Richard F. Mushotzky
We present some results from an archival VLA study of ultraluminous X-ray source s (ULXs). These unresolved non-nuclear X-ray sources have luminosities (L_X >= 1 0^39 ergs/sec) whi…
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 Emergence of the Modern Universe: Tracing the Cosmic Web
J. M. Shull, B. D. Savage, J. A. Morse +8
This is the report of the Ultraviolet-Optical Working Group (UVOWG) commissioned by NASA to study the scientific rationale for new missions in ultraviolet/optical space astronomy 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…
