Formation of Galactic Center Magnetic Loops
Mami Machida, Ryoji Matsumoto, Satoshi Nozawa +7
A survey for the molecular clouds in the Galaxy with NANTEN mm telescope has discovered molecular loops in the Galactic center region. The loops show monotonic gradients of the lin…
Discovery of Large-Scale Gravitational Infall in a Massive Protostellar Cluster
Peter J. Barnes, Yoshinori Yonekura, Stuart D. Ryder +4
We report Mopra (ATNF), Anglo-Australian Telescope, and Atacama Submillimeter Telescope Experiment observations of a molecular clump in Carina, BYF73 = G286.21+0.17, which give evi…
Sub-mm/mm studies of the molecular gas in the Galactic disk; the TeV gamma ray SNR RXJ1713.7-3946 and the W28 high mass star forming region
Yasuo Fukui
Interstellar molecular clouds are gamma ray sources through the interactions with cosmic ray protons followed by production of neutral pions which decay into gamma rays. We present…
Probing the Galactic cosmic ray flux with submillimeter and gamma ray data
S. Casanova, S. Gabici, F. A. Aharonian +5
The study of Galactic diffuse radiation combined with the knowledge of the distribution of the molecular hydrogen in the Galaxy offers a unique tool to probe the cosmic ray flu…
The Molecular Ridge Close to 30 Doradus in the Large Magellanic Cloud
Juergen Ott, Tony Wong, Jorge L. Pineda +9
With the ATNF Mopra telescope we are performing a survey in the 12CO(1-0) line to map the molecular gas in the Large Magellanic Cloud (LMC). For some regions we also obtained inter…
Clumpy photon-dominated regions in Carina. I. [CI] and mid-J CO lines in two 4'x4' fields
C. Kramer, M. Cubick, M. Roellig +31
The Carina region is an excellent astrophysical laboratory for studying the feedback mechanisms of newly born, very massive stars within their natal giant molecular clouds (GMCs) a…
Sub-millimeter Observations of Giant Molecular Clouds in the Large Magellanic Cloud: Temperature and Density as Determined from J=3-2 and J=1-0 transitions of CO
T. Minamidani, N. Mizuno, Y. Mizuno +26
We have carried out sub-mm 12CO(J=3-2) observations of 6 giant molecular clouds (GMCs) in the Large Magellanic Cloud (LMC) with the ASTE 10m sub-mm telescope at a spatial resolutio…
CO, HI, recent Spitzer SAGE results in the Large Magellanic Cloud
Yasuo Fukui
Formation of GMCs is one of the most crucial issues in galaxy evolution. I will compare CO and HI in the LMC in 3 dimensional space for the first time aiming at revealing the physi…
Large-Scale Gravitational Instability and Star Formation in the Large Magellanic Cloud
Chao-Chin Yang, Robert A. Gruendl, You-Hua Chu +2
Large-scale star formation in disk galaxies is hypothesized to be driven by global gravitational instability. The observed gas surface density is commonly used to compute the stren…
Star-forming Regions in the Small Magellanic Cloud Multi-wavelength Properties of Stellar Complexes
E. Livanou, I. Gonidakis, E. Kontizas +6
We trace the star formation regions in the SMC and study their properties. The size and spatial distribution of these regions is found to support the hierarchical scenario of star…
Multi-frequency Study of the LMC Supernova Remnant (SNR) B0513-692 and New SNR Candidate J051327-6911
I. S. Bojicic, M. D. Filipovic, Q. A. Parker +5
We present a new multi-wavelength study of supernova remnant (SNR) B0513-692 in the Large Magellanic Cloud (LMC). The remnant also has a strong, superposed, essentially unresolved,…
Spitzer Survey of the Large Magellanic Cloud, Surveying the Agents of a Galaxy's Evolution (SAGE) I: Overview and Initial Results
Margaret Meixner, Karl D. Gordon, Remy Indebetouw +46
We are performing a uniform and unbiased, ~7x7 degrees imaging survey of the Large Magellanic Cloud (LMC), using the IRAC and MIPS instruments on board the Spitzer Space Telescope…
Giant Molecular Clouds in Local Group Galaxies
Leo Blitz, Yasuo Fukui, Akiko Kawamura +3
We present the first comparative study of extragalactic GMCs using complete data sets for entire galaxies and a uniform set of reduction and analysis techniques. We present results…
A multi-resolution analysis of the radio-FIR correlation in the Large Magellanic Cloud
A. Hughes, T. Wong, R. Ekers +5
We investigate the local correlation betwen the 1.4 GHz radio continuum and 60 micron far-infrared (FIR) emission within the Large Magellanic Cloud (LMC) on spatial scales between…
