Witnessing the growth of the nearest galaxy cluster

Published Date






We present results from the last Suzaku Key Project dedicated to cluster outskirts studies, namely a mosaic of 60 pointings exploring the Virgo Cluster from its centre out to beyond the virial radius along 4 different directions. We discuss the thermodynamical properties in the intracluster medium of this dynamically young system, focusing on departures from hydrodynamic equilibrium and from the expected baseline pressure and entropy profiles. Moreover, we present measurements of the chemical composition of the ICM at large radii and discuss the implication of these results for the chemical enrichment history in the Universe.
