Jets represent an important tool to explore the properties of the hot and dense nuclear matter created in heavy-ion collisions. However, their reconstruction presents a challenging task due to the extremely large and fluctuating background that overwhelms the true hard jet population. We present recent measurements of charged jets in Au plus Au collisions, by the STAR collaboration at RHIC, where the background is suppressed via a new technique based on event mixing. The measured observable is the semi-inclusive yield of recoil jets from a high pT hadron trigger. This jet measurement allows a comparison of jet quenching at RHIC and the LHC and provides new constraints on theoretical calculations of jet quenching.
