The dominance of turbulence over magnetism in the formation of massive star cluster seeds
Junhao Liu, Patricio Sanhueza, Piyali Saha +32
High-mass stars form in protoclusters, where gravo-magnetic processes shape collapsing clouds and clumps to be elongated preferentially perpendicular to magnetic (B) fields. Yet it…
BISTRO Survey: Gravity-Dominated and Magnetically Regulated Star Formation in M17 SW
Mengke Zhao, Keping Qiu, Ji-hyun Kang +27
We present high-resolution magnetic field maps of the M17 SW molecular cloud using JCMT 850 m dust polarization at a scale of 14. The magnetic field exhibits a distinct arc…
Scale-Aware Adversarial Analysis: A Diagnostic for Generative AI in Multiscale Complex Systems
Mengke Zhao, Guang-Xing Li, Duo Xu +1
Complex physical systems, from supersonic turbulence to the macroscopic structure of the universe, are governed by continuous multiscale dynamics. While modern machine learning arc…
Curvature Mapping Method: Mapping Lorentz Force in Orion A
Mengke Zhao, Guang-Xing Li, Keping Qiu
Magnetic force is a fundamental force in nature. Although widely believed to be important in counterbalancing against collapse in star formation, a clear evaluation of the role of…
The Column Density Probability Density Function of Cygnus-X
Yuchen Xing, Keping Qiu
The density distribution within molecular clouds offers critical insights into their underlying physical processes, which are essential for understanding star formation. As a stati…
Equation vs. AI: Predict Density and Measure Width of molecular clouds by Multiscale Decomposition
Mengke Zhao, Guang-Xing Li, Duo Xu +1
Interstellar medium widely exists in the universe at multi-scales. In this study, we introduce the {\it Multi-scale Decomposition Reconstruction} method, an equation-based model de…
