PhD Position - 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. The position advertised here is located at the "Sim & Data Lab Astronomy and Astrophysics“ (SDLAA) of the Jülich Supercomputing Centre (JSC). JSC operates one of the most advanced supercomputing infrastructures for scientific applications in Europe – including JUPITER, the first exascale supercomputer in Europe. The 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. The discovery of interstellar objects passing our Solar System raises the questions of their role in the larger picture of star and planet formation. The position advertised here provides the unique opportunity to work in this emerging new field.
