Galaxy clusters can be a very powerful source of information for both cosmology and astrophysics, especially if results from both observations and numerical simulations are combined to this scope. In particular, the intra-cluster medium (ICM) is an optimal target for this, since it represents about 80 per cent of the visible, baryonic matter in clusters. A promising approach is to use numerical simulations in order to produce synthetic X-ray data, which makes the comparison between simulated clusters and real ones more faithful.
In this way, we can address a number of interesting issues, constrain the success of the numerical modeling, but also predict the capabilities of up-coming X-ray instruments (such as Athena) to capture the observable signatures of the underlying physical processes taking place in galaxy clusters.
The audience is cordially invited to discuss and comment.
During this 30-minutes lunch event of the series "Fruits of the Universe", we will serve drinks and fingerfood.
