Data Centre for Cosmological Simulations – Cosmowebportal

More on the Cosmowebportal from Excellence Cluster University:

“A group of astrophysicists led by Dr. Klaus Dolag from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich in close collaboration with the LRZ have 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, also developed by Klaus Dolag’s team and carried out at the LRZ.

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 mimicing existing or future space telescopes.

“Large astronomical projects such as the space telescopes Euclid or eRosita, which are to be launched in the next few years, will observe large areas of the Universe, as well as provide further insight into the evolution of the first structures of the Universe so that the significance of cosmological hydrodynamic simulations will even increase in future,” says Klaus Dolag. “A data centre that pools and makes these simulations available therefore is an important facility for scientists working in the field.”

Besides Klaus Dolag and Antonio Ragagnin, scientists from the following institutions were involved in the project: C2PAP, the data center of the Excellence Cluster Universe, LRZ, University of Trieste, the INAF Osservatorio Astronomico di Trieste and the Max Planck Computing and Data Facility.”
