Molecular Cloud Formation out of the magnetized ISM

We present results from our investigation of molecular cloud (MC) formation by transonic converging flows in the magnetized, warm neutral medium (WNM). This study is based on AMR simulations with the FLASH and RAMSES codes which include parameterized cooling and heating, magnetic fields, self-gravity and accreting sink particles. We compare our results to a non magnetized study. Overdense, star-forming clumps form out of thermal instabilities (TI) and grow by outward propagation of the transition layer and coalescence. The morphology and intrinsic properties of these clumps resemble cold, quiescent, pressure confined cores but are highly time dependent. The global collapse of the dynamically formed MC produces dense regions which have typical properties of massive star forming regions. We also report on the magnetic field-density relation and the mass-to-flux ratio in the molecular cloud.
