Accretion, Jets, and Recoil in a Merging Supermassive Black Hole Binary: A Prompt Electromagnetic Postmerger Counterpart for LISA
Maria Chiara de Simone, Manuela Campanelli, Lorenzo Ennoggi +2
We report the first three-dimensional general relativistic magnetohydrodynamic simulation to follow, self-consistently in a dynamical spacetime, the magnetized gas around a misalig…
The merger of spinning, accreting supermassive black hole binaries
Lorenzo Ennoggi, Manuela Campanelli, Julian Krolik +3
Because they are likely to accrete substantial amounts of interstellar gas, merging supermassive binary black holes are expected to be strong multimessenger sources, radiating grav…
Relativistic gas accretion onto supermassive black Hole binaries from inspiral through merger
Lorenzo Ennoggi, Manuela Campanelli, Yosef Zlochower +8
Accreting supermassive black hole binaries are powerful multimessenger sources emitting both gravitational and EM radiation. Understanding the accretion dynamics of these systems a…
AsterX: a new open-source GPU-accelerated GRMHD code for dynamical spacetimes
Jay V. Kalinani, Liwei Ji, Lorenzo Ennoggi +10
We present AsterX, a novel open-source, modular, GPU-accelerated, fully general relativistic magnetohydrodynamic (GRMHD) code designed for dynamic spacetimes in 3D Cartesian coordi…
Ameliorating the Courant-Friedrichs-Lewy condition in spherical coordinates: A double FFT filter method for general relativistic MHD in dynamical spacetimes
Liwei Ji, Vassilios Mewes, Yosef Zlochower +5
Numerical simulations of merging compact objects and their remnants form the theoretical foundation for gravitational wave and multi-messenger astronomy. While Cartesian-coordinate…
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…
Implementing a new recovery scheme for primitive variables in the general relativistic magnetohydrodynamic code Spritz
Jay V. Kalinani, Riccardo Ciolfi, Wolfgang Kastaun +3
General relativistic magnetohydrodynamic (GRMHD) simulations represent a fundamental tool to probe various underlying mechanisms at play during binary neutron star (BNS) and neutro…
HARM3D+NUC: A new method for simulating the post-merger phase of binary neutron star mergers with GRMHD, tabulated EOS and neutrino leakage
Ariadna Murguia-Berthier, Scott C. Noble, Luke F. Roberts +25
The first binary neutron star merger has already been detected in gravitational waves. The signal was accompanied by an electromagnetic counterpart including a kilonova component p…
