Presentation description

Critical phenomena occur in systems with just enough mass to be on the verge of collapsing into a black hole. To address the computational restraints of fully 3D simulations, we are investigating these phenomena in axisymmetry. We developed a codebase capable of solving our (2 + 1) + 1 decomposition of GR using finite differencing and wavelet adaptive refinement. We present results from critical point searches and simulations of near-critical scalar fields and brill waves in axisymmetry.
