First Results from the Swift/UVOT Near-Ultraviolet Survey of the SMC

POSTER

Abstract

The Swift Ultraviolet/Optical Telescope (UVOT) has recently completed the first wide-field multi-color NUV survey of the Small Magellanic Cloud. The resulting images, the product of nearly two complete days of imaging, covers nearly four square degrees and includes over 250,000 NUV sources. We present early analysis of this outstanding data set, looking at the recent star formation history of the SMC, the distribution of young stellar populations over the face of the SMC, the location of rare stellar types such as Post-Asymptotic Giant Branch stars, and the SMC dust extinction law.
