Mergers of galaxy clusters: simulating dissociative clusters, shocks and gas sloshing — Rubens Machado (UTFPR)
28 de julho de 2017: 12:30 - 13:30
Galaxy clusters often exhibit X-ray morphologies suggestive of recent interaction with an infalling subcluster. The collision of two clusters often gives rise to disturbances in the intracluster gas (such as shocks, cold fronts, gas sloshing), and these can be studied through numerical simulations. Furthermore, in dissociative cluster mergers, an offset develops between the peak of X-ray emission and the dark matter peak. I will discuss the modelling of a few observed clusters by means of dedicated hydrodynamical simulations that aim at reconstructing their dynamical histories.
