Shear-gravity transition determines the steep velocity dispersion-size relation in molecular clouds: confronting analytical formula with observations

Yi-Heng Xie, Guang-Xing Li

The velocity dispersion-size relation ( $σ_{v} \sim R^{β}$ ) is a crucial indicator of the dynamic properties of interstellar gas, where the slope is considered as $β \sim 0.5$ . Rece…

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…
