HST-WFPC2 Observations of the Star Clusters in the Giant HII Regions of M33
Myung Gyoon Lee, Hong Soo Park, Sang Chul Kim +4
We present a photometric study of the stars in ionizing star clusters embedded in several giant HII regions of M33 (CC93, IC 142, NGC 595, MA2, NGC 604 and NGC 588). Our photometry…
Emission-Line Properties of the LMC Bubble N70
Brooke P. Skelton, William H. Waller, Richard F. Gelderman +4
We present a spectrophotometric imaging study of the emission bubble N70 (DEM 301) in the Large Magellanic Cloud. N70 is approximately 100 pc in size with a nearly circular shell-l…
UV Signposts of Resonant Dynamics in Disk Galaxies
William H. Waller, Christine Winslow, Michael Fanelli +1
Imaging in the restframe ultraviolet has proven to be an effective and vital means of tracing dynamical patterns of star formation in galaxies out to high redshifts. Using images f…
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…
