The evolution of the molecular interstellar medium is controlled by processes such as turbulence, gravity, stellar feedback, and Galactic shear. AL a part of the ISM-6D project, using Gaia astrometric measurements towards a sample of young stellar objects (YSOs), we study the morphology and kinematic structure of the associated molecular gas. We identify 150 YSO associations with distance $d \lesssim 3 \,\,\rm kpc$. The YSO associations are elongated, with a median aspect ratio of 1.97, and…

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
