  We review recent progress in the application of numerical relativity
techniques to astrophysics and high-energy physics. We focus on some
developments that took place within the "Numerical Relativity and High Energy
Physics" network, a Marie Curie IRSES action that we coordinated, namely: spin
evolution in black hole binaries, high-energy black hole collisions, compact
object solutions in scalar-tensor gravity, superradiant instabilities and hairy
black hole solutions in Einstein's gravity coupled to fundamental fields, and
the possibility to gain insight into these phenomena using analog gravity
models.
