Recent results on hard processes in p+Pb, Pb+Pb, and pp collisions from the ATLAS Experiment at the LHC

Measurements of recent results on hard probes in p+Pb, Pb+Pb, and pp collision systems are presented. This includes measurements of electro-weak bosons, jets, and quarkonia. Electro-weak boson results serve as a reference for other measurements, while jets and quarkonia investigate properties of the hot dense medium produced in heavy ion collisions.
