Impact of densitized lapse slicings on evolutions of a wobbling black hole
U. Sperhake, K. L. Smith, B. Kelly +2
We present long-term stable and second-order convergent evolutions of an excised wobbling black hole. Our results clearly demonstrate that the use of a densitized lapse function ex…

Moving black holes via singularity excision
D. Shoemaker, K. Smith, U. Sperhake +3
We present a singularity excision algorithm appropriate for numerical simulations of black holes moving throughout the computational domain. The method is an extension of the excis…
