Abstract	Measurements of inclusive jet suppression in PbPb collions at $sqrtsnn=2.76$ TeV with the ATLAS detector are reported. The centrality, pt and jet size dependence of the central-to-peripheral ratio, Rcp, is presented. The results indicate that jets are suppressed by approximately a factor of two in the most central collisions, and a significant dependence on the jet size is observed. The path length dependence of jet quenching is studied through measurements of inclusive jet suppression as a function of angle with respect to the event plane. The azimuthal modulation of the jet yield is quantified by a jet v2 which is significant in all pt and centrality ranges presented.
