Physical Properties and Galactic Distribution of Molecular Clouds identified in the Galactic Ring Survey

Julia Roman-Duval, James M. Jackson, Mark Heyer +2

We derive the physical properties of 580 molecular clouds based on their 12CO and 13CO line emission detected in the University of Massachusetts-Stony Brook (UMSB) and Galactic Rin…

An Infrared through Radio Study of the Properties and Evolution of IRDC Clumps

Cara Battersby, John Bally, James M. Jackson +4

We examine the physical properties and evolutionary stages of a sample of 17 clumps within 8 Infrared Dark Clouds (IRDCs) by combining existing infrared, millimeter, and radio data…

X-ray Shadowing Experiments Toward Infrared Dark Clouds

Loren D. Anderson, Steve L. Snowden, Thomas M. Bania

We searched for X-ray shadowing toward two infrared dark clouds (IRDCs) using the MOS detectors on XMM-Newton to learn about the Galactic distribution of X-ray emitting plasma. IRD…

The "Nessie" Nebula: Cluster Formation in a Filamentary Infrared Dark Cloud

James M. Jackson, Susanna C. Finn, Edward T. Chambers +2

The "Nessie" Nebula is a filamentary infrared dark cloud (IRDC) with a large aspect ratio of over 150:1 (1.5 degrees x 0.01 degrees, or 80 pc x 0.5 pc at a kinematic distance of 3.…

The Green Bank Telescope Galactic H II Region Discovery Survey

T. M. Bania, L. D. Anderson, Dana S. Balser +1

We discovered a large population of previously unknown Galactic H II regions by using the Green Bank Telescope to detect their hydrogen radio recombination line emission. Since rec…

Molecular outflows within the filamentary infrared dark cloud G34.43+0.24

Patricio Sanhueza, Guido Garay, Leonardo Bronfman +3

We present molecular line observations, made with angular resolutions of ~20", toward the filamentary infrared dark cloud G34.43+0.24 using the APEX [CO(3-2), 13CO(3-2), C18O(3-2)…

A possible generation mechanism for the IBEX ribbon from outside the heliosphere

S. Grzedzielski, M. Bzowski, A. Czechowski +3

The brightest and most surprising feature in the first all-sky maps of Energetic Neutral Atoms (ENA) emissions (0.2-6 keV) produced by the Interstellar Boundary Explorer (IBEX) is…

The Enigmatic Young Low-Mass Variable TWA 30

Dagny L. Looper, Subhanjoy Mohanty, John J. Bochanski +8

TWA 30 is a remarkable young (7+/-3 Myr), low-mass (0.12+/-0.04 Msun), late-type star (M5+/-1) residing 42+/-2 pc away from the sun in the TW Hydrae Association. It shows strong ou…
