The morphology and kinematics of the molecular interstellar medium are controlled by processes such as turbulence, gravity, stellar feedback, and Galactic shear. Using a sample of 15149 young stellar objects (YSOs) with Gaia Data Release 2 (DR2) astrometric measurements, we study morphology and kinematic structure of their associated molecular gas. We identify 150 YSO associations with distance d . 3 kpc. The YSO associations are oriented parallel to the disk midplane, with a median angle of 30…

MHD Turbulence in Star-Forming Regions and the Interstellar Medium
MHD turbulence plays a central role in the physics of star-forming molecular clouds and the interstellar medium. MHD turbulence in molecular clouds must be driven to account for the observed
