Cold Dust in Hot Regions

Gopika Sreenilayam, Michel Fich, Peter Ade +12

We mapped five massive star forming regions with the SCUBA-2 camera on the James Clerk Maxwell Telescope (JCMT). Temperature and column density maps are obtained from the SCUBA-2 4…

A molecular line scan in the Hubble Deep Field North

R. Decarli, F. Walter, C. Carilli +20

We present a molecular line scan in the Hubble Deep Field North (HDF-N) that covers the entire 3mm window (79-115 GHz) using the IRAM Plateau de Bure Interferometer. Our CO redshif…

Mid-Infrared Imaging of the Bipolar Planetary Nebula M2-9 from SOFIA

M. W. Werner, R. Sahai, J. Davis +10

We have imaged the bipolar planetary nebula M2-9 using SOFIA's FORCAST instrument in six wavelength bands between 6.6 and 37.1 . A bright central point source, unresolved with…

The Mrk 231 molecular outflow as seen in OH

E. González-Alfonso, J. Fischer, J. Graciá-Carpio +12

We report on the Herschel/PACS observations of OH in Mrk 231, with detections in 9 doublets observed within the PACS range, and present radiative transfer models for the outflowing…

SIGGMA: A Survey of Ionized Gas in the Galaxy, Made with the Arecibo Telescope

B. Liu, T. Mclntyre, Y. Terzian +5

A Survey of Ionized Gas in the Galaxy, made with the Arecibo telescope (SIGGMA) uses the Arecibo L-band Feed Array (ALFA) to fully sample the Galactic plane (30 < l < 75 and -2 < b…

SOFIA/FORCAST Imaging of the Circumnuclear Ring at the Galactic Center

R. M. Lau, T. L. Herter, M. R. Morris +2

We present 19.7, 31.5, and 37.1 μm images of the inner 6 pc of the Galactic Center of the Milky Way with a spatial resolution of 3.2 - 4.6'' taken by the Faint Object Infrared Came…

The Spatial Distribution of Organics toward the High-Mass YSO NGC 7538 IRS9

Karin I. Oberg, Mavis Dufie Boamah, Edith C. Fayolle +3

Based on astrochemical theory, the complex molecular composition around high-mass YSOs should evolve from the outer envelope in toward the central hot region as a sequence of tempe…

ALFALFA Discovery of the Nearby Gas-Rich Dwarf Galaxy Leo~P. II. Optical Imaging Observations

Katherine L. Rhode, John J. Salzer, Nathalie C. Haurberg +8

We present results from ground-based optical imaging of a low-mass dwarf galaxy discovered by the ALFALFA 21-cm HI survey. Broadband (BVR) data obtained with the WIYN 3.5-m telesco…

Gas and dust cooling along the major axis of M33 (HerM33es): ISO/LWS CII observations

C. Kramer, J. Abreu-Vicente, S. Garcia-Burillo +12

We aim to better understand the heating of the gas by observing the prominent gas cooling line [CII] at 158um in the low-metallicity environment of the Local Group spiral galaxy M3…

A three-phase chemical model of hot cores: the formation of glycine

Robin T. Garrod

A new chemical model is presented that simulates fully-coupled gas-phase, grain-surface and bulk-ice chemistry in hot cores. Glycine (NH2CH2COOH), the simplest amino acid, and rela…
