A CO detection in the off-plane region of the edge-on galaxy NGC 4565 with the Nobeyama 45-m telescope
Ren Matsusaka, Fumi Egusa, Fumiya Maeda +1
Understanding the cycling of interstellar medium (ISM) between the galactic plane and off-plane regions is crucial for tracing the evolution of disk galaxies. We present CO(…
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…
Molecular Gas Structure and Star Formation Diversity in Stephan's Quintet Revealed by ACA CO(1-0) Mapping
Misaki Yamamoto, Fumiya Maeda, Kazuyuki Muraoka +10
We present CO(1-0) mapping across the entire system of Stephan's Quintet, a well-known compact galaxy group, observed by Atacama Compact Array (7\,m array + Total Power) of…
An AGN in the Antennae galaxies ?
Shinya Komugi, Toshiki Saito, Tomonari Michiyama +5
Time variability is a strong probe of energetic phenomena which occur at small spatial scales, like Active Galactic Nuclei (AGN). We use ALMA observations at 100 GHz executed over…
Sub-kpc scale gas density histograms of the nearby barred spiral galaxy M83: Multi-component molecular gas structure reflecting the galactic environment
Ren Matsusaka, Toshihiro Handa, Fumi Egusa +8
We investigate the sub-kiloparsec (sub-kpc) molecular ISM structure and its relation to the galactic environment and star formation in the barred spiral galaxy M83 (NGC 5236). We e…
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…
