Cl J1449+0856 is a spectroscopically confirmed galaxy cluster at z ∼ 2. The detection of a faint, extended X-ray emission, suggestive of an already evolved, partially relaxed structure, puts this system among the most distant established clusters rather than in the realm of zâ‰32 proto-clusters. This gives us a chance of studying galaxies in an evolved overdense environment very close to their formation epoch, and in particular to trace the evolution of early-type galaxies in clusters back to ten billion years ago.
