The Role of Gas Streams in the Formation and Structure of Galaxy Clusters
In recent years it has become increasingly clear that mass accretion onto galactic systems in general and galaxy clusters in particular does not occur in a quasi-spherical manner, but rather along well defined streams. This new scenario for mass accretion can have a marked effect on the structure and dynamics of clusters. By employing high resolution numerical simulations, I investigate the interplay between the internal structure of the intra-cluster gas and the streams along which mass accretes onto the cluster, in the hopes of better understanding some of the questions raised by observations of these systems.
