Measurement of hard probes in $p$+Pb and Pb+Pb Collisions with the ATLAS detector

Recent measurements from the ATLAS experiment of high-$p_\mathrm{T}$ processes in relativistic proton-lead and lead-lead interactions at the Large Hadron Collider (LHC) are presented. In particular, the inclusive jet production results are reviewed including the centrality dependence of the jet nuclear modification factors (NMF) for $p$+Pb and Pb+Pb collisions at energies of $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV and 2.76 TeV, respectively. Additionally, recent results on the electroweak boson rates in Pb+Pb collisions are presented and compared to the theoretical model predictions. The hard probe measurements provide important information on the initial conditions as well as on the properties of the dense medium created in heavy ion collsions.
