Lifting the Dusty Veil II: A Large-Scale Study of the Galactic Infrared Extinction Law

G. Zasowski, S. R. Majewski, R. Indebetouw +8

We combine near-infrared (2MASS) and mid-infrared (Spitzer-IRAC) photometry to characterize the IR extinction law (1.2-8 microns) over nearly 150 degrees of contiguous Milky Way mi…

Hubble Space Telescope NICMOS Polarization Observations of Three Edge-on Massive YSOs

Janet P. Simpson, Michael G. Burton, Sean W. J. Colgan +4

Massive young stellar objects (YSOs), like low-mass YSOs, appear to be surrounded by optically thick envelopes and/or disks and have regions, often bipolar, that are seen in polari…

Star Formation in the Central 400 pc of the Milky Way: Evidence for a Population of Massive YSOs

F. Yusef-Zadeh, J. W. Hewitt, R. G. Arendt +8

The central kpc of the Milky Way might be expected to differ significantly from the rest of the Galaxy with regard to gas dynamics and the formation of YSOs. We probe this possibil…

The Extended Environment of M17: A Star Formation History

Matthew S. Povich, Ed Churchwell, John H. Bieging +9

M17 is one of the youngest and most massive nearby star-formation regions in the Galaxy. It features a bright H II region erupting as a blister from the side of a giant molecular c…

IR Dust Bubbles II: Probing the Detailed Structure and Young Massive Stellar Populations of Galactic HII Regions

C. Watson, T. Corn, E. B. Churchwell +4

We present an analysis of late-O/early-B-powered, parsec-sized bubbles and associated star-formation using 2MASS, GLIMPSE, MIPSGAL and MAGPIS surveys. Three bubbles were selected f…
