Abstract

The X-ray satellite Chandra is the only telescope able to provide high-resolution (~1 arcsec) images in the X-ray band (0.5-10 keV). An international collaboration met in January 2014 at the Villa Il Gioiello to discuss the Chandra Large Program on the high redshift (z=1.58) galaxy cluster XDCP J0044.0-2033, constituting the deepest X-ray observation currently achieved on a massive, high redshift cluster. Thanks to this unprecedented observation, coupled to a wealth of optical and IR data, we are able to investigate the properties of the Intra Cluster Medium, star formation and nuclear activity in the cluster galaxies, and to measure the total mass of the cluster, for the first time at such a high redshift.
