Binary Black Hole Puncture Initial Data with Physics-Informed Neural Networks
Thiago Assumpção, Ignacio Brevis, Irene Pitsiladi +2
We present Pinndorama, a physics-informed neural network (PINN) code for solving the Hamiltonian constraint in the puncture formalism. The networks are trained solely on the govern…
Scalar emission from binary neutron stars in scalar-tensor theories with kinetic screening
Ramiro Cayuso, Adrien Kuntz, Thiago Assumpcao +2
We investigate the scalar emission from binary neutron stars in shift-symmetric scalar-tensor theories with kinetic screening (-essence), using 3+1 numerical simulations in the…
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…
BHaHAHA: A Fast, Robust Apparent Horizon Finder Library for Numerical Relativity
Zachariah B. Etienne, Thiago Assumpção, Leonardo Rosa Werneck +1
Apparent horizon (AH) finders are essential for characterizing black holes and excising their interiors in numerical relativity (NR) simulations. However, open-source AH finders to…
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…
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…
