Simulating the Universe on Supercomputers

The evolution of cosmic structure

Mark Vogelsberger

The evolution of structure in the Universe is one of the hottest topics in Cosmology and Astrophysics. In the last years the so-called $\Lambda$-CDM-model could be established also with great help of very large computer simulations. This model describes a Universe that consists mainly of dark components: 96% are made of dark energy and dark matter. Ordinary matter made up of baryons give only 4% to the total content of the Universe. The talk will present recent results with the main focus on computational methods and challenges in that field. A state-of-the-art computer code for running these calculations will be presented in detail.
