Gamma-ray bursts (GRBs) are the most luminous explosions in the universe ( L ~ 10 50 - 10 52 erg s -1 ).Long GRBs are thought to originate from the collapse of stripped-envelope massive stars. In this talk, I will present numerical simulations of the propagation of a relativistic jet through the progenitor and after its breakout. Since electromagnetic observations cannot fully reveal the physical properties of the jet within the stellar envelope, I will discuss a promising candidate for gravitational wave (GW) emission arising from ultra-relativistic jets. Our results indicate that key parameters of jet propagation can be inferred from this GW signal and detected by future instruments such as LISA, BBO, DECIGO, and ALIA. These results suggest that future GW detections associated with GRB jets could provide a complete picture of jet evolution together with electromagnetic counterparts.
