Abstract: Recent hydrodynamic simulations and observations of radio jets have shown that the surrounding environment has a large effect on their resulting morphology. To investigate this we use a sample of 50 Extended Radio Active Galactic Nuclei (ERAGN) detected in the Observations of Redshift Evolution in Large Scale Environments (ORELSE) survey at z～1. We found that ERAGN are more compact in high-density environments than those in low-density environments. In this talk, I will discuss my results in this recent published paper, along with other studies on the relationship between cluster environments and morphology of ERAGN at similar redshift. All of these studies support a coherent scenario that the dense intracluster gas in the central regions of galaxy clusters plays a major role in confining the spatial extent of radio jets.
