Morphological Identification of Dynamical Regimes in MHD Turbulence with ScaleAware-JEPA
Mengke Zhao, Guang-Xing Li, Keping Qiu
The morphology of turbulent interstellar gas reflects the coupled action of turbulence, magnetic fields, and self-gravity, but density amplitude alone does not uniquely specify dyn…
Gravity-driven Emergence of Multi-fractal Density Structure in the Orion A Integral Shaped Filament
Mengke Zhao, Guang-Xing Li, Keping Qiu +1
Molecular clouds are often described as self-similar structures, although spatially averaged measures do not retain local variations in density scaling. We use the density exponent…
Scale-Vector Alignment: A Scale-Aware Framework for Spatially Resolved Morphological Similarity in Astronomical Images
Mengke Zhao, Guang-Xing Li, Keping Qiu +1
Astronomical maps made with different tracers are not expected to have identical morphology. Excitation, optical depth, chemistry, radiation, and ISM phase alter the response of a…
A Unified Magnetohydrodynamic Scaling Relation for the Multiphase Interstellar Medium
Mengke Zhao, Guang-Xing Li, Keping Qiu
The interplay of magnetic fields, turbulence, and gravity governs the structural evolution of the interstellar medium (ISM) and the initial conditions of star formation, yet observ…
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…
Filamentary Network and Magnetic Field Structures Revealed with BISTRO in the High-Mass Star-Forming Region NGC2264 : Global Properties and Local Magnetogravitational Configurations
Jia-Wei Wang, Patrick M. Koch, Seamus D. Clarke +154
We report 850 m continuum polarization observations toward the filamentary high-mass star-forming region NGC 2264, taken as part of the B-fields In STar forming Regions Observat…
Magnetic Fields in Giant Filaments Probed by the Velocity Gradient Technique: Regular Magnetic Field interrupted by Magnetization Gaps
Mengke Zhao, Guang-Xing Li, Jianjun Zhou +7
We study the magnetic field structures in six giant filaments associated with the spiral arms of the Milky Way by applying the Velocity Gradient technique (VGT) to the 13CO spectro…
