A wide research program provided by heavy ion collisions is ongoing at the Large Hadron Collider with the aim of studying the properties of QCD matter at extreme temperatures and densities. The large acceptance, high granularity and broad pseudorapidity coverage of the ATLAS Detector is well suited to perform detailed analyses on signatures of the QGP, such as collective phenomena, electroweak probes, quarkonia, charged particles and jets. In this seminar, the latest results on these observables will be presented, including comparisons with those produced in lighter p+Pb and pp collisions, as well as with theoretical predictions.
