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…
Accelerated gas flow along Ophiuchus B44 filament: Breaking Position-Position-Velocity degeneracy
J. Alves, C. Zucker, C. Lada +15
(Abridged) Stellar feedback from massive stars in the Upper-Sco has been proposed to have reshaped the gas in the nearby Ophiuchus complex. In this framework, feedback organizes th…
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…
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…
