An invited Living Reviews article on the status and applications of Numerical Relativity is now available, entitle "Exploring New Physics Fronteirs Through Numerical Relativity". The article, co-authored by Vitor Cardoso (CENTRA/IST), Leonardo Gualtieri (Rome "La Sapienza"), Carlos Herdeiro (Aveiro) and Ulrich Sperhake (Cambridge) fills an important gap in the literature, by reviewing the applications of numerical relativity in astrophysics, high-energy physics, fundamental physics and particle physics.
