Abstract

We provide a method to describe the geometry of an analytic, exponentially localized 5D5D rotating braneworld black hole, using the 5D5D Janis Newman algorithm in Hopf coordinates. The induced metric on the brane matches the standard 4D4D Kerr spacetime. Two curvature singularities arise: one confined to the 33-brane at z=r=0z = r = 0, and another that, on the brane, reproduces the Kerr singularity at r=0r = 0, θˉ=π/2\bar{\theta} = \pi/2. The inner and event horizons, together with the stationary limit hypersurfaces, extend into the extra dimension in a pancake-like shape. We describe their behavior in the bulk. The energy momentum tensor represents a source transitioning from an anisotropic, non diagonal structure to a vacuum with negative cosmological constant. Thus, the localized black hole connects to an AdS5_5 boundary. The geometry is supported by a non-diagonal anisotropic fluid in the bulk, requiring no matter on the brane. To evaluate the energy conditions, we use a one form from the dual basis that yields a diagonal energy momentum tensor.
