Review of ATLAS results on heavy ion collisions.

The experimental data collected by the ATLAS experiment provide a broad physics program for studying the properties of de-confined strongly interacting matter, often referred to as “quark gluon plasma” (QGP), created in ultra-relativistic nuclear collisions. The large acceptance and high granularity of the detector is well suited to perform detailed analyses on bulk phenomena, electroweak probes, quarkonia, charged particles and jets. In these proceedings, the latest results on these observables will be described, including comparisons with those produced in lighter p+Pb and pp collisions. The latest observation of the light-by-light scattering process in ultraperipheral Pb+Pb collisions at √sNN = 5.02 TeV is included as well.
