Recent heavy ion results from ATLAS experiment

During the first three years of operation the ATLAS experiment has collected an integrated luminosity of $0.15~\mathrm{nb}^{-1}$ for $\sqrt{s_{NN}}=2.76~$TeV lead-lead collisions, $30~\mathrm{nb}^{-1}$ for 5.02 TeV proton-lead collisions, and $5~\mathrm{pb}^{-1}$ for $\sqrt{s}=2.76~$TeV proton-proton collisions. The proton-lead and the high-statistics 2.76 TeV proton-proton data recorded during the highly successful 2013 LHC heavy ion run provide valuable control measurements for interpreting results from lead-lead collisions. Measurements of bulk particle production are presented with a focus on studies of elliptic and higher-order collective flow. Included in these results are measurements of event-by-event collective flow. In addition to providing baseline measurements for the lead-lead program, the proton-lead data also provide a unique opportunity to study the physics of soft and hard scattering in a high parton density environment. Two-particle correlations in relative azimuthal angle $(\Delta\phi)$ and pseudorapidity $(\Delta\eta)$ measured in $\sqrt{s_{NN}}=5.02$ TeV p+Pb collisions are presented.
