Discovery of a New Molecular Bubble-Outflow Structure in the Taurus B18 Cloud
Yan Duan, Di Li, Paul F. Goldsmith +5
Star formation can produce bubbles and outflows, as a result of stellar feedback. Outflows and bubbles inject momentum and energy into the surrounding interstellar medium, and so a…
Non-detection of Broad Hydrogen Radio Recombination Lines in Circinus Galaxy
Junzhi Wang, Yong Shi, Zhi-Yu Zhang +5
The line widths of broad line regions (BLRs) of AGNs are key parameters for understanding the central super massive black holes (SMBHs). However, due to obscuration from dusty toru…
Properties of dense molecular gas along the major axis of M 82
Fei Li, Zhi-Yu Zhang, Junzhi Wang +6
Dense gas is important for galaxy evolution and star formation. Optically-thin dense-gas tracers, such as isotopologues of HCN, HCO+, etc., are very helpful to diagnose excitation…
Deuterated ammonia in Galactic massive star-forming regions
Yuqiang Li, Junzhi Wang, Juan Li +2
We present sensitive observations of NH2D at 110.153599 GHz toward 50 Galactic massive star-forming regions with IRAM 30-m telescope. The NH2D transition is detected toward 36 obje…
Spatial distribution of HOCN around Sagittarius B2
Siqi Zheng, Juan Li, Junzhi Wang +4
HOCN and HNCO abundance ratio in molecular gas can tell us the information of their formation mechanism. We performed high-sensitivity mapping observations of HOCN, HNCO, and HNC$^…
Widespread subsonic turbulence in Ophiuchus North 1
Yan Gong, Shu Liu, Junzhi Wang +4
Supersonic motions are common in molecular clouds. (Sub)sonic turbulence is usually detected toward dense cores and filaments. However, it remains unknown whether (sub)sonic motion…
