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…
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…
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…
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…
Galactic Contrail in NGC 3627 caused by Dwarf Galaxy Candidate or Massive Black Hole Flyby
Mengke Zhao, Guang-Xing Li
We report the discovery of a kpc scale molecular contrail in the spiral galaxy NGC 3627, a narrow structure spanning 8 kpc in length with a width of 200 pc and an extreme aspect ra…
