The Sim Data Lab Astronomy and Astrophysics is a targeted research and support structure that provides an interface between the Supercomputer facilities in Jülich and the Astrophysics research communities.


Our tasks include the support of Data Science Projects and High Performance Computing Simulations for the Astrophysics Community. We support users in their research by

  • advising code choices for their scientific applications,
  • supporting the development and application of scalable methods,
  • development of an integrated application infrastructure for high performance computational astrophysics (HPCA),
  • supporting the development of data analysis tools,
  • initiation of collaborative projects for advancing high performance computational astrophysics and data science,
  • visualization of the obtained results

In addition, we host repositories of commonly used codes and data bases and offer workshops in above mentioned areas.

Research Topics


Visualization is an important tool for analyzing and understanding simuation data in astronomy and astrophysics. The visualization group at JSC assists users by developing and adapting software tools to meet special needs.

Examples can be seen below.

SDL Astronomy and Astrophysics
Formation of galactic molecular clouds
SDL Astronomy and Astrophysics
Ionization feedback during the birth of a massive star
SDL Astronomy and Astrophysics
Collective outflow from a small stellar cluster

Especially time-dependent effects call for presenting the data in an animation or video. These can be used in presentations, inside websites, presentations or for media purposes. The JSC visualisation team provides hard- and software to capture, edit and publish the content.
