Postdoc for Interstellar Objects

titel

DYNAVERSE is a new Cluster of Excellence lead by the Universities of Cologne and Bonn. Forschungszentrum Jülich is partner in Dynaverse, which is a world-class hub of researchers with with expertise in Astrophysics, Computer Science and Mathematics. State-of-the-art research facilities to which this team has priority access combined with the expertise in high-performance computing, and data-analytics will generate new ground-breaking opportunities. The two positions advertised here are located at the Jülich Supercomputing Centre (JSC) which operates one of the most advanced supercomputing infrastructures for scientific applications in Europe – including JUPITER, the first exascale supercomputer in Europe. The "Sim & Data Lab Astronomy and Astrophysics“ (SDLAA) is a research and support structure that provides an interface between the Supercomputer facilities and the Astrophysics communities, with a research focus on star and planet formation, in particular solar system formation, interstellar objects and young star cluster dynamics.
