  We present two measurements related to jet production in p+p and central
Au+Au collisions at $\sqrt{{s}_{NN}}$=200 GeV. Firstly, a study of
semi-inclusive charged recoil jets coincident with high-$\rm{p_{T}}$
direct-photon and neutral pions, and secondly, the hadron correlations with
respect to reconstructed di-jet triggers. Indication of medium effects is
observed by comparing $\gamma$+jet and $\pi^{0}$+jet measurements. The
di-jet+hadron study shows signs that the medium-induced modifications of an
imbalanced set of di-jets with "hard cores" primarily affect the recoil jet.
