The WISE Catalog of Galactic HII Regions

L. D. Anderson, T. M. Bania, Dana S. Balser +4

Using data from the all-sky Wide-Field Infrared Survey Explorer (WISE) satellite, we made a catalog of over 8000 Galactic HII regions and HII region candidates by searching for the…

MALT90: The Millimetre Astronomy Legacy Team 90 GHz Survey

J. M. Jackson, J. M. Rathborne, J. B. Foster +53

The Millimetre Astronomy Legacy Team 90 GHz (MALT90) survey aims to characterise the physical and chemical evolution of high-mass star-forming clumps. Exploiting the unique broad f…

Hunting The Most Distant Stars in the Milky Way: Methods and Initial Results

John J. Bochanski, Beth Willman, Andrew A. West +2

We present a new catalog of 404 M giant candidates found in the UKIRT Infrared Deep Sky Survey (UKIDSS). The 2,400 deg available in the UKIDSS Large Area Survey Data Release 8…

Chemical Evolution in High-Mass Star-Forming Regions: Results from the MALT90 Survey

Sadia Hoq, James M. Jackson, Jonathan B. Foster +7

The chemical changes of high-mass star-forming regions provide a potential method for classifying their evolutionary stages and, ultimately, ages. In this study, we search for corr…

HI Absorption Toward HII Regions at Small Galactic Longitudes

C. Jones, J. M. Dickey, J. R. Dawson +3

We make a comprehensive study of HI absorption toward HII regions located within Galactic longitudes less than 10 degrees. Structures in the extreme inner Galaxy are traced using t…

Distinct Chemical Regions in the "Prestellar" Infrared Dark Cloud (IRDC) G028.23-00.19

Patricio Sanhueza, James M. Jackson, Jonathan B. Foster +3

We have observed the IRDC G028.23-00.19 at 3.3 mm using CARMA. In its center, the IRDC hosts one of the most massive (~1520 Msun) quiescent, cold (12 K) clumps known (MM1). The low…

Anchors for the Cosmic Distance Scale: the Cepheid QZ Normae in the Open Cluster NGC 6067

D. Majaess, L. Sturch, C. Moni Bidin +13

Cepheids are key to establishing the cosmic distance scale. Therefore it's important to assess the viability of QZ Nor, V340 Nor, and GU Nor as calibrators for Leavitt's law via th…

Near-infrared polarimetry of a normal spiral galaxy viewed through the Taurus Molecular Cloud Complex

Dan P. Clemens, M. D. Pavel, L. R. Cashman

Few normal galaxies have been probed using near-infrared polarimetry, even though it reveals magnetic fields in the cool interstellar medium better than either optical or radio pol…
