Numerical Relativity of Compact Binaries in the 21st Century
Matthew D. Duez, Yosef Zlochower
We review the dramatic progress in the simulations of compact objects and compact-object binaries that has taken place in the first two decades of the twenty-first century. This in…
Comparing an analytical spacetime metric for a merging binary to a fully nonlinear numerical evolution using curvature scalars
Jam Sadiq, Yosef Zlochower, Hiroyuki Nakano
We introduce a new geometrically invariant prescription for comparing two different spacetimes based on geodesic deviation. We use this method to compare a family of recently intro…
Numerical relativity in spherical coordinates with the Einstein Toolkit
Vassilios Mewes, Yosef Zlochower, Manuela Campanelli +3
Numerical relativity codes that do not make assumptions on spatial symmetries most commonly adopt Cartesian coordinates. While these coordinates have many attractive features, sphe…
