Giant Molecular Clouds and Star Formation in the Tidal Molecular Arm of NGC 4039
D. Espada, S. Komugi, E. Muller +23
The properties of tidally induced arms provide a means to study molecular cloud formation and the subsequent star formation under environmental conditions which in principle are di…
Physical Conditions in Molecular Clouds in the Arm and Interarm Regions of M51
J. Koda, N. Scoville, T. Hasegawa +10
We report systematic variations in the CO(2-1)/CO(1-0) line ratio (R) in M51. The ratio shows clear evidence for the evolution of molecular gas from the upstream interarm regions,…
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…
GMC Evolutions in the Nearby Spiral Galaxy M33
Rie E. Miura, Kotaro Kohno, Tomoka Tosaki +13
We present a Giant Molecular Cloud (GMC) catalog toward M33, containing 71 GMCs in total, based on wide field and high sensitivity CO(J=3-2) observations with a spatial resolution…
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…
