An ALMA view of the Jet-Arc CO clouds toward the TeV -ray source HESS J1023-575 and Westerlund 2; Evidence for the footprints of microquasar jets, the very powerful cosmic-ray accelerator in the Galactic disk

Yasuo Fukui, Kisetsu Tsuge, Hidetoshi Sano +7

The TeV -ray source HESS J1023-575 (HESSJ 1023 hereafter) is one of the brightest H.E.S.S. sources near the young massive cluster Westerlund 2. HESS J1023 shows a remarkable pos…

Discovery of CO Clouds Associated with the X-ray Jets of SS 433: Evidence for Shock-Cloud Interaction Enhancing Nonthermal X-ray Emission

Haruka Sakemi, Hidetoshi Sano, Yasuo Fukui +7

We report the first identification of molecular clumps directly associated with the re-brightening regions of the large-scale X-ray jets of SS 433, based on CO ( = 1--0)…

A multi-scale molecular and atomic gas view on the HII region N113 in the Large Magellanic Cloud:Evidence for high-mass star formation triggered by supersonically-colliding HI flows

Rin I. Yamada, Kazuki Tokuda, Yasuo Fukui +15

The Large Magellanic Cloud (LMC) exhibits vigorous high-mass star formation, including the HII regions 30~Dor that is the most active site of star formation in the local group. The…

ALMA Band 9 CO(6--5) Reveals a Warm Ring Structure Associated with the Embedded Protostar in the Cold Dense Core MC 27/L1521F

Kazuki Tokuda, Mitsuki Omura, Naoto Harada +9

Infall and outflows, coupled with magnetic fields, rapidly structure the gas around newborn protostars. Shocks from interacting components encode the temperature and density distri…

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…

A catalog of molecular clouds possibly associated with Galactic infrared bubbles I. The Southern Galactic plane

Mikito Kohno, Yoshiaki Sofue, Yasuo Fukui +1

We have carried out a morphological search for molecular clouds possibly associated with 48 Galactic infrared bubbles with angular radii of in the southern Galactic plane of…
