ATLAS Results on Hard and Electromagnetic Probes in Heavy-Ion Collisions

The ATLAS experiment at the LHC encompasses a wide-ranging physics program that includes a variety of collision systems and energies. These proceedings provide an overview of the recent ATLAS measurements regarding heavy-ion collisions and related topics. The data utilized in the presented results were recorded during LHC Run 2 (2015--2018). The measurements can help to understand various physics phenomena from hard scatterings to soft processes; from large systems through small systems and photon-induced interactions; and from precision measurements to searches for physics beyond the Standard Model.
