Abstract
Detailed measurements of collectivity in Au+Au collisions at RHIC provide a key connection between the initial geometry of the deposited energy and the hydrodynamic evolution of the medium created in heavy-ion collisions. Utilizing the highly segmented PHENIX inner trackers, we present new measurements of flow coefficients extending over a wide range in pseudorapidity 1 < vertical bar eta vertical bar < 3 and p(T). Over a centrality range of 0-90%, we present cumulant results v(2){2}-v(2){8} and v(3){2} as well as quantifying the event-by-event flow fluctuations. Complementing these results, we measure event-by-event v(2) and v(3) distributions using an unfolding procedure.
