| The collisional thermalization between electrons and ions is very slow, due to the large difference in their masses, and it occurs on a millisecond timescale. |
| The system forestalls thermalization because the one-dimensional motion prevents the kind of momentum transfers that generate a broad distribution of energies, Weiss says. |
| The magnitude of the observed anisotropic flow effect is sensitive to the degree of thermalization at the collision's earliest moments. |
| The simulation consists of thermalization, equilibration, and production phases. |
