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…

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…

The CO-to-H Conversion Factor in the Barred Spiral Galaxy M83

Amanda M Lee, Jin Koda, Akihiko Hirota +2

We analyze the CO-to-H conversion factor () in the nearby barred spiral galaxy M83. We present new HI observations from the JVLA and single-dish GBT in the disk of…
