Beginning in 1994, we introduced multi-dimensional
Adaptive Mesh Refinement
(AMR) hydrodynamical techniques into astrophysics
(Klein, McKee and Colella 1994) in a study of the
interaction of supernova blast waves with
interstellar clouds. The high resolution afforded
by AMR shed new light upon the key hydrodynamical
instabilities responsible for the destruction and
mixing of the cloud with the interstellar medium.
Since then, the thrust of our research has been
twofold: (i) to develop and implement
state-of-the-art parallel, multi-dimensional AMR
algorithms and codes incorporating the full range
of coupled physics necessary to address a wide
spectrum of problems in astrophysical fluid
dynamics, including multi-fluid hydrodynamics,
gravity, radiation transport, and magnetic fields;
and (ii) to use these powerful AMR codes to
investigate fundamental problems in astrophysical
fluid dynamics that are characterized by a wide
range of length and time scales, for which AMR is
essential.
The group is currently using our AMR methodology
to study a number of major problems in
astrophysical fluid dynamics:
