Query: Magnetohydrodynamic Simulations of Shock Interactions with Radiative
  Clouds   We present results from two-dimensional numerical simulations of the
interactions between magnetized shocks and radiative clouds. Our primary goal
is to characterize the dynamical evolution of the shocked clouds. We perform
runs in both the strong and weak magnetic field limits and consider three
different field orientations. For the geometries considered, we generally find
that magnetic fields external to, but concentrated near, the surface of the
cloud suppress the growth of destructive hydrodynamic instabilities. External
fields also increase the compression of the cloud by effectively acting as a
confinement mechanism driven by the interstellar flow and local field
stretching. This can have a dramatic effect on both the efficiency of radiative
cooling, which tends to increase with increasing magnetic field strength, and
on the size and distribution of condensed cooled fragments. In contrast, fields
acting predominately internally to the cloud tend to resist compression,
thereby inhibiting cooling. We observe that, even at modest strengths, internal
fields can completely suppress low-temperature cooling.
