Spatially and Dynamically Extended Molecular Gas in Stephan's Quintet Revealed by ALMA CO(1-0) Total Power Mapping
Fumiya Maeda, Shinya Komugi, Kazuyuki Muraoka +15
We present ALMA Total Power CO(1-0) mapping of Stephan's Quintet (SQ), a prototypical compact galaxy group, with a uniform noise level at a spatial scale of ~25 kpc. These observat…
ALMA FACTS III. High-Resolution CO(2-1)/CO(1-0) Maps of Twelve Nearby Galaxies
Amanda M Lee, Jin Koda, Fumi Egusa +4
We present early results from a high-resolution analysis (100-200pc) of the CO(2-1)/CO(1-0) line ratio in twelve nearby galaxies. We use new ALMA CO(1-0) observations from th…
High-Velocity Molecular Clouds in M83
Maki Nagata, Fumi Egusa, Fumiya Maeda +4
High-velocity clouds (HVCs), which are gas clouds moving at high velocity relative to the galactic disk, may play a critical role in galaxy evolution, potentially supplying gas to…
ALMA FACTS. II. Large Scale Variations in the 12CO(J=2-1) to 12CO(J=1-0) Line Ratio in Nearby Galaxies
Shinya Komugi, Tsuyoshi Sawada, Jin Koda +4
We present 12CO(J=1-0) mapping observations over ~1/2 of the optical disk of 12 nearby galaxies from the Fundamental CO 1-0 Transition Survey of nearby galaxies (FACTS), using the…
Dynamically-Driven Evolution of Molecular Gas in M83 Traced by CO 2-1/1-0 Line Ratio Variations
Jin Koda, Fumi Egusa, Akihiko Hirota +3
We show the variations of the CO J=2-1/1-0 line ratio (R21) across the barred spiral galaxy M83, using the 46 pc resolution data from ALMA. The R21 map clearly evidences the system…
Cloud-cloud collisions in the Antennae galaxies: Does high-speed collision suppress star formation?
Shin Inoue, Kouji Ohta, Fumiya Maeda
Cloud-cloud collision (CCC) has been proposed as a mechanism for triggering massive star formation. Observations in the Milky Way and nearby galaxies have revealed the presence of…
Galactic structure dependence of cloud-cloud collisions driven star formation in the barred galaxy NGC 3627
Fumiya Maeda, Kouji Ohta, Fumi Egusa +4
While cloud-cloud collisions (CCCs) have been proposed as a mechanism for triggering massive star formation, it is suggested that higher collision velocities () and lo…
