General relativistic hydrodynamics code for dynamical spacetimes with curvilinear coordinates, tabulated equations of state, and neutrino physics
Terrence Pierre Jacques, Samuel Cupp, Leonardo R. Werneck +3
Many astrophysical systems of interest to numerical relativity-such as rapidly rotating stars, black hole accretion disks, and core-collapse supernovae-exhibit near-symmetries. The…
Insights into Binary Neutron Star Merger Simulations: A Multi-Code Comparison
Maria C. Babiuc Hamilton, William A. Messman
Gravitational Wave (GW) signals from Binary Neutron Star (BNS) mergers provide critical insights into the properties of matter under extreme conditions. Due to the scarcity of obse…
Merging Black Holes: Assessing the Performance of Two Analytic Gravitational Waves Models
Dillon Buskirk, Maria C. Babiuc Hamilton
Merging black holes produce the loudest signal in the detectors. However, this is the most difficult signal to accurately predict with analytical techniques. Only computer simulati…
Eccentric Pairs: Analytic Gravitational Waves from Binary Black Holes in Elliptic Orbits
Dillon Buskirk, Maria C. Babiuc Hamilton
Gravitational waves (GW) from eccentric binaries have intricate signals encoding important features about the location, creation and evolution of the sources. Eccentricity shortens…
A Complete Analytic Gravitational Wave Model for Undergraduates
Dillon Buskirk, Maria C. Babiuc Hamilton
Gravitational waves are produced by orbiting massive binary objects, such as black holes and neutron stars, and propagate as ripples in the very fabric of spacetime. As the waves c…
GiRaFFE: An Open-Source General Relativistic Force-Free Electrodynamics Code
Zachariah B. Etienne, Mew-Bing Wan, Maria C. Babiuc +2
We present GiRaFFE, the first open-source general relativistic force-free electrodynamics (GRFFE) code for dynamical, numerical-relativity generated spacetimes. GiRaFFE adopts the…
Testing the well-posedness of characteristic evolution of scalar waves
M. C. Babiuc, H-O. Kreiss, J. Winicour
Recent results have revealed a critical way in which lower order terms affect the well-posedness of the characteristic initial value problem for the scalar wave equation. The prope…
Binary Black Hole Waveform Extraction at Null Infinity
M. C. Babiuc, J. Winicour, Y. Zlochower
In this work, we present a work in progress towards an efficient and economical computational module which interfaces between Cauchy and characteristic evolution codes. Our goal is…
A Characteristic Extraction Tool for Gravitational Waveforms
M. C. Babiuc, B. Szilagyi, J. Winicour +1
We develop and calibrate a characteristic waveform extraction tool whose major improvements and corrections of prior versions allow satisfaction of the accuracy standards required…
Strategies for the Characteristic Extraction of Gravitational Waveforms
M. C. Babiuc, N. T. Bishop, B. Szilagyi +1
We develop, test and compare new numerical and geometrical methods for improving the accuracy of extracting waveforms using characteristic evolution. The new numerical method invol…
Implementation of standard testbeds for numerical relativity
M. C. Babiuc, S. Husa, D. Alic +8
We discuss results that have been obtained from the implementation of the initial round of testbeds for numerical relativity which was proposed in the first paper of the Apples wit…
