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…
