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…
SENR/NRPy+: Numerical Relativity in Singular Curvilinear Coordinate Systems
Ian Ruchlin, Zachariah B. Etienne, Thomas W. Baumgarte
We report on a new open-source, user-friendly numerical relativity code package called SENR/NRPy+. Our code extends previous implementations of the BSSN reference-metric formulatio…
Evolutions of unequal mass, highly spinning black hole binaries
James Healy, Carlos O. Lousto, Ian Ruchlin +1
We evolve a binary black hole system bearing a mass ratio of and individual spins of and in a configuration where the large b…
Evolutions of Nearly Maximally Spinning Black Hole Binaries Using the Moving Puncture Approach
Yosef Zlochower, James Healy, Carlos O. Lousto +1
We demonstrate that numerical relativity codes based on the moving punctures formalism are capable of evolving nearly maximally spinning black hole binaries. We compare a new evolu…
High Energy Collisions of Black Holes Numerically Revisited
James Healy, Ian Ruchlin, Carlos O. Lousto +1
We use fully nonlinear numerical relativity techniques to study high energy head-on collision of nonspinning, equal-mass black holes to estimate the maximum gravitational radiation…
Puncture Initial Data for Black-Hole Binaries with High Spins and High Boosts
Ian Ruchlin, James Healy, Carlos O. Lousto +1
We solve the Hamiltonian and momentum constraints of general relativity for two black holes with nearly extremal spins and relativistic boosts in the puncture formalism. We use a n…
