Description and Aim
Computational astrophysics is a fast growing discipline which envelopes
computational science, observational astronomy and theoretical physics.
Many recent exciting advances in astrophysics are realized through computation.
With computers it has become possible to perform experiments that cannot
practically be executed in a laboratory, or it is possible to advance time or
to descend from an intergalactic scales down to
planetary scales. The conceptual, theoretical and methodological
foundations necessary to understand these multi-scale processes are
dramatically limited by our ability to translate our physical understanding to
Recent advances in our understanding of self gravitating systems, like the
universe, galaxies, star clusters and planetary systems, has strongly been
driven by the continuous increase in computer capacity and our ability to
utilize the available hardware via software. These advances have
progressed more-or-less independently in the four main astrophysical domains by
the development of relatively separate numerical techniques, which include: symplectic methods, direct N-body, tree-codes and
FFT-mesh-based methods. At the same time computer architectures have
changed, and each of the astrophysical specialized solvers run efficiently on
different hardware, like GRAPE, Graphical Processing Units, shared memory supercomputer
and distributed memory Linux clusters.
Regardless of the recent improvements in our understanding of the Universe it
remains painstakingly clear that a proper appreciation of the complexity at all
scales requires the proper modeling on all scales. But this is dramatically
hampered by computer hardware and by the complexity of the software. The next
generation of computer assisted astrophysics is driven by the development of
advanced multiscale and multi physics software via
the hybridization of the various techniques. For this reason we bring together
a wide range of gravitational astrophycisists and
Objective of the advanced school
We aim at educating the next generation key
researchers in computational gravitational dynamics. Most individual
universities lack the specialized expertise required to model gravitational dynamics
on all scales relevant for understanding the Universe. During this school the
apprentice will work in close collaboration with peers under the supervision of
the key researcher in the field. This small splinter group will conduct a
research project which should culminate in a publication. The school is meant
to last for two weeks, with
supervised research during the first week and independent research in the
second. In the second week the apprentice has the opportunity to attend the
workshop on computational gravitational dynamics at the Lorentz Center.
Students will work in triplets under the supervision of the key researcher.
Together they will work for one week with the possibility to finish the work in
the second week. The results of the project will be presented at the workshop
in the second week and published in a peer reviewed proceedings.
Objective of the workshop
We aim at bringing together a wide range of
computational gravitational dynamicists to discuss
the recent progress and possibilities for interdisciplinary research in this
field. We notice that planetary dynamicists rarely
interact with cosmologists on the numerical details used in their scientific
production software, even though the underlying physics is quite comparable. We
intend to bridge this gap.
Format of the workshop
We will have review talks of a number of invited key researchers, and short
contributed presentations of cross disciplinary researchers, followed by
