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…
