Spacetime in motion: an evolving relativistic binary black hole metric for GIZMO
Giacomo Fedrigo, Alessandro Lupi, Alessia Franchini +1
The last evolutionary stages of massive black hole binaries prior to coalescence is dominated by the emission of gravitational waves, which will be probed by the future Laser Inter…

A general relativistic magnetohydrodynamics extension to mesh-less schemes in the code GIZMO
Giacomo Fedrigo, Alessandro Lupi
The profound comprehension of the evolution and phenomenology of an Active Galactic Nucleus requires an accurate exploration of the dynamics of the magnetized gaseous disk surround…

GRMHD simulations of accretion flows onto massive binary black hole mergers embedded in a thin slab of gas
Giacomo Fedrigo, Federico Cattorini, Bruno Giacomazzo +1
We present general relativistic magnetohydrodynamic simulations of merging equal-mass, spinning black holes embedded in an equatorial thin slab of magnetized gas. We evolve black h…
