Sumario:The ATLAS experiment at the Large Hadron Collider has undertaken a broad jet physics program to probe and characterize the hot nuclear matter created in relativistic lead-lead collisions. The parton shower of hard scattered partons, produced early in the collision, develops as the medium cools and expands, and thus the properties of final-state reconstructed jets are a sensitive probe of medium properties over a variety of temperature and length scales. Recent technical advances in jet reconstruction and calibration in a heavy ion underlying event background have allowed for precise and differential measurements of inclusive jet production, of jet-jet pT and multi-jet production rate correlations, and of internal jet structure. In particular, a recent set of new measurements have focused on better elucidating the flavor, centrality and pT dependence of jet suppression and modification. This talk will give a summary of the latest heavy ion jet results from ATLAS.
