Abstract
The results from the STAR Collaboration on directed flow (${v}_{1}$), elliptic flow (${v}_{2}$), and the fourth harmonic (${v}_{4}$) in the anisotropic azimuthal distribution of particles from Au+Au collisions at $\sqrt{{s}_{\mathit{NN}}}=200\phantom{\rule{0.3em}{0ex}}\mathrm{GeV}$ are summarized and compared with results from other experiments and theoretical models. Results for identified particles are presented and fit with a blast-wave model. Different anisotropic flow analysis methods are compared and nonflow effects are extracted from the data. For ${v}_{2}$, scaling with the number of constituent quarks and parton coalescence are discussed. For ${v}_{4}$, scaling with ${v}_{2}^{2}$ and quark coalescence…
