Results on high transverse momentum charged particle emission with respect to the reaction plane are presented for collisions at . Two- and four-particle correlations results are presented as well as a comparison of azimuthal correlations in collisions to those in at the same energy. The elliptic anisotropy is found to reach its maximum at , then decrease slowly and remain significant up to . Stronger suppression is found in the back-to-back high- particle correlations for particles emitted out of plane compared to those emitted in plane. The centrality dependence of at intermediate is compared to simple models based on jet quenching.
