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…
