CO Multi-line Imaging of Nearby Galaxies (COMING) IV. Overview of the Project
Kazuo Sorai, Nario Kuno, Kazuyuki Muraoka +36
Observations of the molecular gas in galaxies are vital to understanding the evolution and star-forming histories of galaxies. However, galaxies with molecular gas maps of their wh…
ALMA Observations of Giant Molecular Clouds in M33 I: Resolving Star Formation Activities in the Giant Molecular Filaments Possibly Formed by a Spiral Shock
Kazuki Tokuda, Kazuyuki Muraoka, Hiroshi Kondo +14
We report molecular line and continuum observations toward one of the most massive giant molecular clouds (GMCs), GMC-16, in M33 using ALMA with an angular resolution of 044 $\…
ALMA CO Observations of a Giant Molecular Cloud in M33: Evidence for High-Mass Star Formation Triggered by Cloud-Cloud Collisions
Hidetoshi Sano, Kisetsu Tsuge, Kazuki Tokuda +14
We report the first evidence for high-mass star formation triggered by collisions of molecular clouds in M33. Using the Atacama Large Millimeter/submillimeter Array, we spatially r…
Discovery of Shocked Molecular Clouds Associated with the Shell-Type Supernova Remnant RX J0046.57308 in the Small Magellanic Cloud
H. Sano, H. Matsumura, Y. Yamane +25
RX J0046.57308 is a shell-type supernova remnant (SNR) in the Small Magellanic Cloud (SMC). We carried out new CO( = 1-0, 3-2) observations toward the SNR using Mopra…
CO Multi-line Imaging of Nearby Galaxies (COMING). III. Dynamical effect on molecular gas density and star formation in the barred spiral galaxy NGC 4303
Yoshiyuki Yajima, Kazuo Sorai, Nario Kuno +24
We present the results of CO(=1-0) and CO(=1-0) simultaneous mappings toward the nearby barred spiral galaxy NGC 4303 as a part of the CO Multi-line Imaging of…
CO Multi-line Imaging of Nearby Galaxies (COMING): VI. Radial variations in star formation efficiency
Kazuyuki Muraoka, Kazuo Sorai, Yusuke Miyamoto +25
We examined radial variations in molecular-gas based star formation efficiency (SFE), which is defined as star formation rate per unit molecular gas mass, for 80 galaxies selected…
CO Multi-line Imaging of Nearby Galaxies (COMING). VII. Fourier decomposition of molecular gas velocity fields and bar pattern speed
Dragan Salak, Yuto Noma, Kazuo Sorai +24
The CO velocity fields of a sample of 20 nearby spiral galaxies, selected from the CO Multi-line Imaging of Nearby Galaxies (COMING) legacy project of No…
