Local and Approximate classification of spacetimes in the transverse frames
Nicole Rosato, Hiroyuki Nakano, Carlos O. Lousto
We revisit the definition of transverse frames and tetrad choices with regards to its application to numerically generated spacetimes, in particular those from the merger of binary…

Adapted gauge to small mass ratio binary black hole evolutions
Nicole Rosato, James Healy, Carlos O. Lousto
We explore the benefits of adapted gauges to small mass ratio binary black hole evolutions in the moving puncture formulation. We find expressions that approximate the late time be…

Adapted gauge to a quasilocal measure of the black holes recoil
James Healy, Carlos O. Lousto, Nicole Rosato
We explore different gauge choices in the moving puncture formulation in order to improve the accuracy of a linear momentum measure evaluated on the horizon of the remnant black ho…
