Gravitational-Wave Signatures of Massive Black Hole Formation
Bernard J. Kelly, Sarah Gossan, Leonardo R. Werneck +5
Direct-collapse black holes (DCBHs) are an important component of the massive black hole population of the early universe, and their formation and early mergers will be prominent i…
GRHayL: a modern, infrastructure-agnostic, extensible library for GRMHD simulations
Samuel Cupp, Leonardo R. Werneck, Terrence Pierre Jacques +2
Interpreting multimessenger signals from neutron stars and black holes requires reliable general relativistic magnetohydrodynamics (GRMHD) simulations across rapidly evolving high-…
Ultra-low damping of the translational motion of a composite graphite rod in a magneto-gravitational trap
Connor E. Murphy, Cody Jessup, Tahereh Naderishahab +5
We demonstrate an ultra-low dissipation, one-dimensional mechanical oscillator formed by levitating a millimeter-scale composite graphite rod in a room-temperature magneto-gravitat…
Accelerating Numerical Relativity with Code Generation: CUDA-enabled Hyperbolic Relaxation
Samuel D. Tootle, Leonardo R. Werneck, Thiago Assumpção +2
Next-generation gravitational wave detectors such as Cosmic Explorer, the Einstein Telescope, and LISA, demand highly accurate and extensive gravitational wave (GW) catalogs to fai…
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…
Toward 2D Dynamo Models Calibrated by Global 3D Relativistic Accretion Disk Simulations
Matthew D. Duez, Courtney L. Cadenhead, Zachariah B. Etienne +2
Two-dimensional models assuming axisymmetry are an economical way to explore the long-term evolution of black hole accretion disks, but they are only realistic if the feedback of t…
The Dynamics of Debris Disk Creation in Neutron Star Mergers
Yossef Zenati, Julian Krolik, Leonardo Werneck +4
The detection of GW170817/AT2017gfo inaugurated an era of multimessenger astrophysics, in which gravitational wave and multiwavelength photon observations complement one another to…
Cross-correlation image analysis for real-time particle tracking
Leonardo R. Werneck, Cody Jessup, Austin Brandenberger +6
Accurately measuring the translations of objects between images is essential in many fields, including biology, medicine, chemistry, and physics. One important application is track…
Bound Debris Expulsion from Neutron Star Merger Remnants
Yossef Zenati, Julian H. Krolik, Leonardo R. Werneck +4
Many studies have found that neutron star mergers leave a fraction of the stars' mass in bound orbits surrounding the resulting massive neutron star or black hole. This mass is a s…
Addition of tabulated equation of state and neutrino leakage support to IllinoisGRMHD
Leonardo R. Werneck, Zachariah B. Etienne, Ariadna Murguia-Berthier +11
We have added support for realistic, microphysical, finite-temperature equations of state (EOS) and neutrino physics via a leakage scheme to IllinoisGRMHD, an open-source GRMHD cod…
Handing off the outcome of binary neutron star mergers for accurate and long-term post-merger simulations
Federico G. Lopez Armengol, Zachariah B. Etienne, Scott C. Noble +20
We perform binary neutron star (BNS) merger simulations in full dynamical general relativity with IllinoisGRMHD, on a Cartesian grid with adaptive-mesh refinement. After the remnan…
