In close collaboration with the Excellence Cluster Universe and the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences, we now initiated "Cosmowebportal". This unique data centre for cosmological simulations provides access to the results of the world's most extensive set of cosmological hydrodynamic simulations, Magneticum Pathfinder. The complete simulations are saved at the LRZ in Garching on a data store for large datasets, which is connected to the supercomputer SuperMUC. Using a web interface, interested scientists can, for example, select objects from the raw simulation data, process it and even create virtual observations mimicking existing or future space telescopes.
Visualizations of the simulated distributions of gas and stars in the Universe from data provided by Cosmowebportal: The cube represents a space section of the Universe (more than 300 million light years), the bright spots on the cube faces show galaxies and galaxy clusters along the cosmic web. The first two disks zoom into the central galaxy cluster, the third disk (far right) demonstrates how an observation of the zoom area would look with an X-ray telescope ("virtual telescope").
