Abstract
The PHENIX experiment at the Relatimay invistic Heavy Ion Collider has collected data scanning system sizes from p+p and 3He+Au to Au+Au and U+U at collision energies from √SNN = 7.7 to 510 GeV. The extensive measurements from these data improve our understanding of the Quark Gluon Plasma and the origin of the proton spin. PHENIX’s measurements of π0 mesons, photons, heavy flavor particles, and jets probe the formation of the QGP, and measurements of azimuthal anisotropies are sensitive to collective effects and the initial geometry of the collision. A selection of recent results from PHENIX with an emphasis on results from heavy ion collisions are discussed.
