  We analyze the emergence of synchronization in a population of moving
integrate-and-fire oscillators. Oscillators, while moving on a plane, interact
with their nearest neighbor upon firing time. We discover a non-monotonic
dependence of the synchronization time on the velocity of the agents. Moreover,
we find that mechanisms that drive synchronization are different for different
dynamical regimes. We report the extreme situation where an interplay between
the time-scales involved in the dynamical processes completely inhibit the
achievement of a coherent state. We also provide estimators for the transitions
between the different regimes.
