Galaxy clusters in simulations of the local Universe: a matter of constraints

Understand

To study the full formation and evolution history of galaxy clusters and their population, high resolution simulations of the latter are flourishing.

• However comparing observed clusters to the simulated ones on a one-to-one basis to refine the models and theories down to the details is non trivial.
• The large variety of clusters limits the comparisons between observed and numerical clusters.
• Simulations resembling the local Universe down to the cluster scales permit pushing the limit.
