Atomic Shocks in the Outflow of L1551 IRS 5 Identified with SOFIA-upGREAT Observations of [OI]
Yao-Lun Yang, Neal J. Evans, Agata Karska +5
We present velocity resolved SOFIA/upGREAT observations of [OI] and [CII] lines toward a Class I protostar, L1551 IRS 5, and its outflows. The SOFIA observations detect [OI] emissi…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- IV. Radio Recombination Lines and evolution of star formation efficiencies
C. Zhang, Neal J. Evans, T. Liu +11
We report detection of radio recombination line (RRL) H toward 75 sources, with data obtained from ACA observations in the ATOMS survey of 146 active Galactic star forming…
TIMES II: Investigating the Relation Between Turbulence and Star-forming Environments in Molecular Clouds
Hyeong-Sik Yun, Jeong-Eun Lee, Neal J. Evans +14
We investigate the effect of star formation on turbulence in the Orion A and Ophiuchus clouds using principal component analysis (PCA). We measure the properties of turbulence by a…
Planck Galactic Cold Clumps at High Galactic Latitude-A Study with CO Lines
Fengwei Xu, Yuefang Wu, Tie Liu +28
Gas at high Galactic latitude is a relatively little-noticed component of the interstellar medium. In an effort to address this, forty-one Planck Galactic Cold Clumps at high Galac…
TIMES I: a Systematic Observation in Multiple Molecular Lines Toward the Orion A and Ophiuchus Clouds
Hyeong-Sik Yun, Jeong-Eun Lee, Yunhee Choi +16
We have used the Taeduk Radio Astronomy Observatory to observe the Orion A and Ophiuchus clouds in the 10 lines of CO, CO, HCN, HCO, and NH and the…
