Random gas motions inside sub-parsec scale supercritical filaments
Chao Zhang, Tie Liu, Mika Juvela +12
Supercritical gas filaments in molecular clouds host the dense cores in which new stars form. The mechanisms governing their formation and subsequent gas accretion remain poorly un…
Correlations of Methyl Formate (CH3OCHO), Dimethyl Ether (CH3OCH3) and Ketene (H2CCO) in High-mass Star-forming Regions
Chuanshou Li, Sheng-Li Qin, Tie Liu +10
We present high-spatial-resolution (0.7 to 1.0 arcsec) submillimeter observations of continuum and molecular lines of CH3OCHO, CH3OCH3, and H2CCO toward 11 high-mass star-forming r…
The evolution of molecular clouds: turbulence-regulated global radial collapse
An-Xu Luo, Hong-Li Liu, Jin-Zeng Li
The star formation efficiency (SFE) measures the proportion of molecular gas converted into stars, while the star formation rate (SFR) indicates the rate at which gas is transforme…
Implication of the velocity dispersion scalings on high-mass star formation in molecular clouds
An-Xu Luo, Hong-Li Liu, Sheng-Li Qin +2
This paper is aimed at exploring implications of velocity dispersion scalings on high-mass star formation in molecular clouds, including the scalings of Larson's linewidth--size ($…
What role of gravity, turbulence and magnetic fields in high-mass star formation clouds?
An-Xu Luo, Hong-Li Liu, Guang-Xing Li +2
To explore the potential role of gravity, turbulence and magnetic fields in high-mass star formation in molecular clouds, this study revisits the velocity dispersion--size (--$L…
Multiscale Dynamical Scenario of High-mass Star Formation in an IRDC Filament G34
Sirong Pan, Hong-Li Liu, Sheng-Li Qin
There is growing evidence that high-mass star formation (HMSF) is a multiscale, dynamical process in molecular clouds, where filaments transport gas material between larger and sma…
ALMA-IMF VIII -- Combination of Interferometric Continuum Images with Single-Dish Surveys and Structural Analysis of Six Protoclusters
Daniel J. Díaz-González, Roberto Galván-Madrid, Adam Ginsburg +17
We present the combination of ALMA-IMF and single-dish continuum images from the Mustang-2 Galactic Plane Survey (MGPS90) at 3 millimeters and the Bolocam Galactic Plane Survey (BG…
ALMA observations of NGC 6334S. II. Subsonic and Transonic Narrow Filaments in a High-mass Star Formation Cloud
Shanghuo Li, Patricio Sanhueza, Chang Won Lee +22
We present a study of narrow filaments toward a massive infrared dark cloud, NGC 6334S, using the Atacama Large Millimeter/submillimeter Array (ALMA). Thirteen gas filaments are id…
Herschel observations of the Galactic HII region RCW 79
Hong-Li Liu, Miguel Figueira, Annie Zavagno +12
Triggered star formation around HII regions could be an important process. The Galactic HII region RCW 79 is a prototypical object for triggered high-mass star formation. We take a…
