Formation of star-forming clouds from the magnetised, diffuse
  interstellar medium
  Molecular clouds, the birthplaces of stars in galaxies, form dynamically from
the diffuse atomic gas of the interstellar medium (ISM). The ISM is also
threaded by magnetic fields which have a large impact on its dynamics. In
particular, star forming regions must be magnetically supercrit- ical in order
to accomodate gas clumps which can collapse under their own weight. Based on a
parameter study of three dimensional magneto-hydrodyamical (MHD) simulations,
we show that the long-standing problem of how such supercritical regions are
generated is still an open issue.
