Query: Black-hole head-on collisions in higher dimensions   The collision of black holes and the emission of gravitational radiation in
higher-dimensional spacetimes are of interest in various research areas,
including the gauge-gravity duality, the TeV gravity scenarios evoked for the
explanation of the hierarchy problem, and the large-dimensionality limit of
general relativity. We present numerical simulations of head-on collisions of
nonspinning, unequal-mass black holes starting from rest in general relativity
with $4 \leq D\leq 10$ spacetime dimensions. We compare the energy and linear
momentum radiated in gravitational waves with perturbative predictions in the
extreme mass ratio limit, demonstrating the strength and limitations of
black-hole perturbation theory in this context.
