I am a theoretical astrophysicist investigating the Universe’s most energetic events, particularly those taking place in the extreme environments around compact objects. My work explores how matter falls into black holes, how relativistic outflows are launched, and how these processes imprint themselves across multiple cosmic messengers. I am also deeply interested in how strong, rapidly evolving gravitational fields –such as those produced during black hole or neutron star mergers– reshape these phenomena. To probe these scenarios, I combine semi-analytical modeling with large-scale numerical simulations.

In this chapter, we give an overview of our current understanding of the physics of accreting massive black hole binaries (MBHBs), with a special focus on the latest developments in numerical simulations and General-Relativistic Magnetohydrodynamics (GRMHD) simulations in particular. We give a self-contained global picture of how to model accretion onto MBHBs, analyzing different aspects of the system such as the dynamics of the circumbinary disk, mini-disks, outflows, the role of magnetic fields, and electromagnetic signatures. We discuss important questions and open problems related to these systems, what are the advantages and disadvantages of the different numerical approaches, and what robust knowledge we have built from simulations.
