Figure 8: Snapshots of the rest-mass density in the collision of fluid balls with boost factor
(upper panels) and
(lower panels) at the initial time, shortly after collision, at the time
corresponding to the formation of separate horizons in the
case, and formation of a common
horizon (for
) and at late time in the dispersion (
) or ringdown (
) phase.
