Magnetic Eruption and Nucleosynthesis in GRνMHD Simulations of Spinning Neutron Star Mergers
Allen Wen, Jay V. Kalinani, Michail Chabanov +3
We present three-dimensional general relativistic magnetohydrodynamics simulations of equal-mass binary neutron star mergers with varied neutron star spin configurations and second…
Jet-environment interaction after delayed collapse in binary neutron star mergers
Jay V. Kalinani, Riccardo Ciolfi, Manuela Campanelli +4
We present general relativistic magnetohydrodynamic simulations of binary neutron star (BNS) mergers, where the collapse of the metastable massive neutron star (MNS) remnant leads…
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…
Accretion, Jets, and Recoil in Merging Supermassive Binary Black Holes
Maria Chiara de Simone, Manuela Campanelli, Lorenzo Ennoggi +2
We report the first 3D general relativistic magnetohydrodynamic (GRMHD) simulation that captures the full, self-consistent evolution from the late inspiral through merger and subse…
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…
GPU-accelerated Subcycling Time Integration with the Einstein Toolkit
Liwei Ji, Roland Haas, Yosef Zlochower +3
Adaptive Mesh Refinement (AMR) with subcycling in time enables different grid levels to advance using their own time steps, ensuring finer grids employ smaller steps for accuracy w…
