Abstract / Description:We have developed a general method for finding apparent horizons in 3D numerical relativity. Instead of
solving for the partial differential equation describing the location of the apparent horizons, we expand the
closed 2D surfaces in terms of symmetric trace-free tensors and solve for the expansion coefficients using a
minimization procedure. Our method is applied to a number of different spacetimes, including numerically
constructed spacetimes containing highly distorted axisymmetric black holes in spherical coordinates, and 3D
rotating, and colliding black holes in Cartesian coordinates.
