Flow Phenomena in Pb-Pb Collisions at ATLAS

Results on the elliptic flow and higher order harmonics of charged particles in Pb+Pb collisions at sqrt(s_NN)=2.76 TeV at ATLAS will be presented. The flow harmonics are measured by correlating azimuthal angles of reconstructed particles with the event plane angle obtained from forward calorimeters as well as with the two-particle correlation method. The elliptic flow is measured over 5 units of pseudorapidity, from -2.5 to 2.5, and over a broad range in transverse momentum, 0.5-20 GeV. Flow Phenomena in Pb-Pb Collisions measured in ATLAS will be discussed in the context of measurements by other experiments and model predictions.
