Head-tail molecular clouds falling onto the Milky Way disk
Mikito Kohno, Yasuo Fukui, Takahiro Hayakawa +13
We report discovery of two CO clouds which are likely falling down to the Galactic plane at more than km s. The clouds show head-tail distributions elongated perpendicu…

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…

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…
