A kinematic analysis of the giant molecular complex W3: Possible evidence for cloud-cloud collisions that triggered OB star clusters in W3 Main and W3(OH)
Bieging, John H.; Tachihara, Kengo; Fukui, Yasuo +6 more
W3 is one of the most outstanding regions of high-mass star formation in the outer solar circle, and includes two active star-forming clouds: W3 Main and W3(OH). Based on a new analysis of the
Q-band line survey observations toward a carbon-chain-rich clump in the Serpens South region
Lai, Shih-Ping; Liu, Sheng-Yuan; Nakamura, Fumitaka +17 more
We have conducted Q-band (30-50 GHz) line survey observations toward a carbon-chain emission peak in the Serpens South cluster-forming region with the extended Q-band (eQ) receiver installed on the Nobeyama 45 m radio telescope. Approximately 180 lines have been detected, including tentative detection, and these lines are attributed to 52 molecule…
KAgoshima Galactic Object survey with Nobeyama 45 m telescope by Mapping in Ammonia lines (KAGONMA): Discovery of parsec-scale CO depletion in the Canis Major star-forming region
Shimajiri, Yoshito; Sunada, Kazuyoshi; Omodaka, Toshihiro +6 more
In observational studies of infrared dark clouds, the number of detections of CO freeze-out on to dust grains (CO depletion) at the pc scale is extremely limited, and the conditions for its occurrence are, therefore, still unknown. We report a new object where pc-scale CO depletion is expected. As part of the Kagoshima Galactic Object survey with …
