Magnetising the quokka code with fast, second-order accurate, error-correcting schemes for magnetohydrodynamics on GPUs
Neco Kriel, Elizabeth Cole-Kodikara, Benjamin Wibking +4
We implement a second-order accurate constrained transport (CT) magnetohydrodynamics (MHD) module with first-order flux correction in the open-source, adaptive mesh refinement (AMR…
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{C…
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…
The ALMA-QUARKS Survey: Discovery of Superfine Dusty Fibrils inside Massive Star-forming Clumps
Yan-Kun Zhang, Tie Liu, Wenyu Jiao +35
We report the discovery of more than 320 superfine dusty filamentary structures (fibrils) inside 121 massive star forming clumps that are located in widely different Galactic envir…
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 (200…
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…
A novel algorithm for GPU-accelerated particle-mesh interactions implemented in the QUOKKA code
Chong-Chong He, Benjamin D. Wibking, Aditi Vijayan +2
We present a novel, GPU-optimized algorithm for particle-mesh interactions in grid-based hydrodynamics simulations, designed for massively parallel architectures. This approach ove…
ALMASOP. Detection of Turbulence-induced Mass Assembly Shocks in Starless Cores
Shih-Ying Hsu, Sheng-Yuan Liu, Xunchuan Liu +8
Star formation is a series of mass assembly processes and starless cores, those cold and dense condensations in molecular clouds, play a pivotal role as initial seeds of stars. Wit…
Cloud2to3: Three-dimensional reconstruction via spherization
Xunchuan Liu, Pak-Shing Li
Inferring three-dimensional structures from two-dimensional maps remains a major challenge due to line of sight degeneracies. We present Cloud2to3, a flexible framework to reconstr…
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…
INvestigations of massive Filaments ANd sTar formation (INFANT). I. Core Identification and Core Mass Function
Yu Cheng, Xing Lu, Patricio Sanhueza +16
Filamentary structures are ubiquitously found in high-mass star-forming clouds. To investigate the relationship between filaments and star formation, we carry out the INFANT (INves…
The magnetic field in colliding filaments G202.3+2.5
Qi-Lao Gu, Tie Liu, Pak Shing Li +19
We observe the magnetic field morphology towards a nearby star-forming filamentary cloud, G202.3+2.5, by the JCMT/POL-2 850 μm thermal dust polarization observation with an angular…
Magnetic Fields in the Central Molecular Zone Influenced by Feedback and Weakly Correlated with Star Formation
Xing Lu, Junhao Liu, Thushara Pillai +12
Magnetic fields of molecular clouds in the Central Molecular Zone (CMZ) have been relatively underobserved at sub-parsec resolution. Here we report JCMT/POL2 observations of polari…
