Numerical Relativity in Axisymmetry

Numerical relativity, the branch of general relativity that uses simulations to solve the Einstein equations, has proven an in-
valuable tool in studying gravity, from gravitational wave astronomy to foundational questions such as cosmic censorship
and space-time stability studies. Most current numerical relativity codes use Cartesian or spherical coordinates, which are
not ideally suited to many systems that present structure around an axis, examples of which are black hole head-on collisions and
critical collapse around an axis. In this talk, I present the new code I have created to do numerical relativity simulations with
a free choice of spatial coordinates, and present results and simulations in both cylindrical and spherical coordinates.
