We present first measurements of the varphi-meson elliptic flow (v_{2}(p_{T})) and high-statistics p_{T} distributions for different centralities from sqrt[s_{NN}]=200 GeV Au+Au collisions at RHIC. In minimum bias collisions the v_{2} of the varphi meson is consistent with the trend observed for mesons. The ratio of the yields of the Omega to those of the varphi as a function of transverse momentum is consistent with a model based on the recombination of thermal s quarks up to p_{T} approximately 4 GeV/c, but disagrees at higher momenta. The nuclear modification factor (R_{CP}) of varphi follows the trend observed in the K_{S};{0} mesons rather than in Lambda baryons, supporting baryon-meson scaling. These data are consistent with varphi mesons in central Au+Au collisions being created via coalescence of thermalized s quarks and the formation of a hot and dense matter with partonic collectivity at RHIC.
