Young star clusters in the extended UV disk of M83
M. Andersen, A. Zavagno, J. Koda +2
The process of star formation in a low-metallicity environment and whether it differs from star formation in the solar neighbourhood is an open topic. Recently, CO clumps were iden…
Insights into Jet-Induced Cloud Disruption in NGC 1316: ALMA Reveals a Spatially Extended Molecular Gas
Kana Morokuma-Matsui, Alexander Y. Wagner, Filippo M. Maccagni +14
We present ALMA CO() observations of a nearby radio galaxy NGC1316 at a 100-pc resolution to investigate the impact of AGN jets on the molecular gas. The molecular gas exhib…
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…
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…
Whole-disk sampling of molecular clouds in M83
Akihiko Hirota, Jin Koda, Fumi Egusa +17
We present a catalog of clouds identified from the CO (1--0) data of M83, which was observed using Atacama Large Millimeter/submillimeter Array (ALMA) with a spatial resolut…
