Kolmogorov turbulence across multi-fractal gas in Polaris Flare
Xunchuan Liu, Pak-Shing Li, Yihuan Di
We reveal a pristine, scale-invariant 3D Kolmogorov velocity cascade () spanning --~pc in the Polaris Flare using \texttt{PPCOS} $^{12}\text{…
Magnetic Fields in Massive Star-forming Regions (MagMaR). VII. On the dynamical importance of B-fields in massive protocluster W33 A
Fengwei Xu, Q. Zhang, P. Sanhueza +30
Magnetic fields (B-fields) are likely important in massive protocluster formation, but their role remains poorly constrained. We present 1.2 mm ALMA full-polarization observations…
ALMA Polarization Study of the Magnetic Fields in Two Massive Clumps in the 20 km s Cloud of the Central Molecular Zone
Yuhua Liu, Xing Lu, Junhao Liu +14
We present the Atacama Large Millimeter/submillimeter Array (ALMA) observations of linearly polarized 870 m continuum emission at a resolution of 0.2 (20…
The ALMA-QUARKS Survey: Discovery of Dusty Fibrils inside Massive Star-forming Clumps
Yan-Kun Zhang, Tie Liu, Wenyu Jiao +35
We report the discovery of more than 323 superfine dusty filamentary structures (fibrils) inside 121 massive star forming clumps that are located in widely different Galactic envir…
Ubiquity of Methanol and its related Chemical Segregation in Orion Starless Cores: the ALMASOP Sample
Shih-Ying Hsu, Sheng-Yuan Liu, Xunchuan Liu +8
Complex organic molecules (COMs) in starless cores provide critical insights into the early stages of star formation and prebiotic chemistry. We present a chemical survey of 16 sta…
Network of velocity-coherent filaments formed by supersonic turbulence in a very-high-velocity HI cloud
Xunchuan Liu, Tie Liu, Pak-Shing Li +17
The warm neutral medium (WNM) was thought to be subsonically/transonically turbulent, and it lacks a network of intertwined filaments that are commonly seen in both molecular cloud…
