ALOHA IRDCs Molecular Line Follow-up: I. Gas properties and kinematics
Jinjin Xie, Yaoting Yan, Zhiyuan Ren +109
Infrared Dark Clouds are ideal sites for investigating the initial conditions of massive star and cluster formation. The A Lei Of the Habitat and Assembly of Infrared Dark Clouds (…
An inverted infall profile for the collapse of the massive star-forming IRDC SDC335.579-0.292
Jinjin Xie, Gary A. Fuller, Di Li +8
There is increasing evidence for global collapse of clumps over parsec-scales in massive star formation regions. Such collapse may result in characteristic molecular line emission…
Large scale mapping of [CI] and the [CI]-to-CO transition in Ophiuchus molecular cloud
Jifeng Xia, Ningyu Tang, Thomas G. Bisbas +10
Atomic carbon ([CI]) is a key species in the carbon chemistry of the interstellar medium (ISM). Using the Submillimeter Wave Astronomy Satellite (SWAS), we conducted a [CI](P$_…
The Distribution of UV Radiation Field in the Molecular Clouds of Gould Belt
Jifeng Xia, Ningyu Tang, Qijun Zhi +5
The distribution of ultraviolet (UV) radiation field provides critical constraints on the physical environments of molecular clouds. Within 1 kpc of our solar system and fostering…
Precise Measurements of CH Maser Emission and Its Abundance in Translucent Clouds
Ningyu Tang, Di Li, Gan Luo +5
We present high-sensitivity CH 9 cm ON/OFF observations toward 18 extra-galactic continuum sources that have been detected with OH 18 cm absorption in the Millennium survey with th…
Studying Infall in Infrared Dark Clouds with Multiple HCO+ Transitions
Jinjin Xie, Jingwen Wu, Gary A. Fuller +9
We investigate the infall properties in a sample of 11 infrared dark clouds (IRDCs) showing blue-asymmetry signatures in HCO J=1--0 line profiles. We used JCMT to conduct map…
