Unveiling a network of parallel filaments in the Infrared Dark Cloud G14.225-0.506
Gemma Busquet, Qizhou Zhang, Aina Palau +10
We present the results of combined NH3(1,1) and (2,2) line emission observed with the Very Large Array and the Effelsberg 100m telescope of the Infrared Dark Cloud G14.225-0.506. T…
The thermal state of molecular clouds in the Galactic Center: evidence for non-photon-driven heating
Y. Ao, C. Henkel, K. M. Menten +6
We used the Atacama Pathfinder Experiment (APEX) 12 m telescope to observe the J_KaKc=3_03-2_02, 3_22-2_21, and 3_21-2_20 transitions of para-H_2CO at 218 GHz simultaneously to det…
Ammonia in the hot core W51-IRS2: 12 new maser lines and a maser component with a velocity drift
C. Henkel, T. L. Wilson, H. Asiri +1
With the 100-m telescope at Effelsberg, 19 ammonia (NH3) maser lines have been detected toward the prominent massive star forming region W51-IRS2. Eleven of these inversion lines,…
NRO M33 All-Disk Survey of Giant Molecular Clouds (NRO MAGiC): II. Dense Gas Formation within Giant Molecular Clouds in M33
Sachiko Onodera, Nario Kuno, Tomoka Tosaki +9
We report the results of our observations of the 12CO (J=1-0) and 12CO (J=3-2) line emission of 74 major giant molecular clouds (GMCs) within the galactocentric distance of 5.1 kpc…
Properties of Molecular Gas in Galaxies in Early and Mid Stage of the Interaction: I. Distribution of Molecular Gas
Hiroyuki Kaneko, Nario Kuno, Daisuke Iono +4
We present the results of 12CO(J = 1-0) mapping observations toward four interacting galaxies in early and mid stages of the interaction to understand the behavior of molecular gas…
Structured Molecular Gas Reveals Galactic Spiral Arms
Tsuyoshi Sawada, Tetsuo Hasegawa, Jin Koda
We explore the development of structures in molecular gas in the Milky Way by applying the analysis of the brightness distribution function (BDF) and the brightness distribution in…
