Isotropic equivalent kinetic energy
The high-energy sports game analogy from the crianca summary describes a burst of new energy being injected into the system, allowing players to boost their performance. This is similar to how the shockwave in this GRB got refreshed with new energy for about 9 seconds after the initial explosion.
Technical definition
Isotropic equivalent kinetic energy refers to the total energy released by an astrophysical event, such as a gamma-ray burst, in a form that can be compared and contrasted across different observations.
