At RHIC, the study of dihadron correlations has been one of the primary methods used to investigate the propagation and modification of hard-scattered partons in the QGP. Due to recent advancements in jet-finding algorithms it is now possible to use reconstructed jets as triggers in these correlation studies. I show results of a systematic study of jet-hadron correlations in 200 GeV p+p and central Au+Au collisions. It is observed that the associated hadron yield of the awayside jet is significantly suppressed in Au+Au compared to p+p at high transverse momentum, and energetically balanced in large part by enhancement at low transverse momentum. A significant source of systematic uncertainty in the jet-hadron correlations analysis is the subtraction of the combinatoric background, since jet v2 and jet v3, which describe the correlations of the jet axis with the second- and third-order participant planes, are unknown.
In this talk I discuss progress towards measurements of jet vn.
