This paper reviews the fundamental physics of magnetic fields in accretion disks and jets, emphasizing numerical modeling and observational constraints on their role in active galaxy jets across scales.

Contribution

It provides a comprehensive overview of magnetic field physics, modeling efforts, and observational data related to disk-jet systems in active galaxies.

Findings

Magnetic fields are crucial for jet launching and collimation.

Numerical models have advanced understanding of jet-disk interactions.

Observations support the significance of magnetic fields in active galaxy jets.

Abstract

Magnetic fields are fundamental to the dynamics of both accretion disks and the jets that they often drive. We review the basic physics of these phenomena, the past and current efforts to model them numerically with an emphasis on the jet-disk connection, and the observational constraints on the role of magnetic fields in the jets of active galaxies on all scales.
