Morphology of molecular clouds at kiloparsec scale in the Milky Way: Shear-induced alignment and vertical confinement
Yi-Heng Xie, Guang-Xing Li, Bing-Qiu Chen
The shape of the cold interstellar molecular gas is determined by several processes, including self-gravity, tidal force, turbulence, magnetic field, and galactic shear. Based on t…
