Recent ATLAS measurements in heavy-ion collisions

This talk presents an overview of recent ATLAS measurements in heavy ion collision systems. These include multiple measurements of jet production and jet structure, which probe the dynamics of the hot, dense Quark-Gluon Plasma formed in relativistic nucleus-nucleus collisions, and measurements of quarkonia and heavy flavor production to probe the QGP medium properties. Furthermore, an overview of the latest ultra-peripheral physics measurements of photon-photon fusion processes will be discussed. Studies of processes in photon-photon interactions constrain the nuclear photon flux, the tau lepton's anomalous magnetic dipole moment (g-2), and provide a unique opportunity to investigate extensions of the Standard Model.
