CO observations toward the isolated mid-infrared bubble S44: External triggering of O-star formation by a cloud-cloud collision
Mikito Kohno, Kengo Tachihara, Shinji Fujita +11
We have performed a multi-wavelength study of the mid-infrared bubble S44 to investigate the origin of isolated high-mass star(s) and the star-formation process around the bubble f…
ALMA CO Observations of Supernova Remnant N63A in the Large Magellanic Cloud: Discovery of Dense Molecular Clouds Embedded within Shock-Ionized and Photoionized Nebulae
H. Sano, H. Matsumura, T. Nagaya +19
We carried out new CO( = 1-0, 3-2) observations of a N63A supernova remnant (SNR) from the LMC using ALMA and ASTE. We find three giant molecular clouds toward the northe…
Molecular gas in a Spitzer bubble N4: possible evidence for cloud-cloud collisions as a trigger of massive star formation
