Numerically calibrated model for propagation of a relativistic unmagnetized jet in dense media

Understand

Relativistic jets reside in high-energy astrophysical systems of all scales.

• Their interaction with the surrounding media is critical as it determines the jet evolution, observable signature, and feedback on the environment.
• During its motion the interaction of the jet with the ambient media inflates a highly pressurized cocoon, which under certain conditions collimates the jet and strongly affects its propagation.
• Recently, Bromberg et al.
