The Flash Center for Computational Science has been
home to several cross-disciplinary computational
research projects in its 20-year existence.
Anchoring our work is the FLASH code, an open
radiation MHD simulation code for plasma physics and
astrophysics with a wide international user base.
Research projects include the on-going development
of the FLASH code, the study of astrophysical
processes mediated by magnetic fields, HPC
simulation campaigns on the largest supercomputers
in the world, and our breakthrough Laboratory
Astrophysics experiments at the world's largest
laser facilities. READ

Magnetic fields are everywhere in the universe, from the
Sun and other stars, to galaxies and clusters of
galaxies. But the origin of these magnetic fields, and
why they are as strong as they are, remain a mystery.
Nonlinear amplification of seed magnetic fields by
turbulence is a widely invoked explanation for how
cosmic magnetic fields become as strong as we observe
them to be. But this mechanism – which is called the
turbulent dynamo – has never been demonstrated in the
laboratory.
Now, an international team of scientists led by the
Flash Center for Computational Science has been awarded
time at the Omega laser – one of the most powerful
lasers in the world – to create a magnetized turbulent
plasma and see if the seed magnetic fields are amplified
by an enormous amount, as scientists have postulated. To
do this, the team fires intense lasers at two targets,
creating two plasma jets that each flow through a grid
and become turbulent. The jets then collide, making the
plasma even more turbulent. The experiment is expected
to produce magnetic Reynolds numbers Rm > 1000 – far
greater than the value Rm > 200 theorists say is needed
for the turbulent dynamo mechanism to work.
The international scientific team conducting the
experiment includes members from the University of
Oxford, UK; the University of Rochester; the
Massachusetts Institute of Technology; Lawrence
Livermore National Laboratory; ETH Zurich, Switzerland;
Ecole Polytechnique, France; and the Ulsan National
Institute of Science and Technology, Korea; as well as
the Flash Center at the University of Rochester. The
experiment at the Omega laser and the Flash Center’s
research in high energy density physics are both
supported by the U.S. Department of Energy National
Nuclear Security Administration.
FLASH full-physics 3D simulation of the Omega TDYNO experiments. Two foil targets, machined with cylindrical wells in the center, are illuminated with lasers to drive colliding flows. In the path of the flows, two meshes are placed to stir turbulence with a controlled driving scale. The time lapses of magnetic field magnitude show the laser-driven jets traversing the grids and colliding at the center. The self-generated Biermann battery fields are amplified to hundreds of kG by the induced turbulence.
