'Disc-jet' coupling in black hole X-ray binaries and active galactic nuclei

TL;DR

This paper reviews the current understanding of the relationship between accretion processes and outflows in black hole systems, focusing on the coupling between disk and jet emissions across different scales.

Contribution

It synthesizes observational evidence from X-ray binaries and active galactic nuclei to elucidate the disk-jet coupling in black hole accretion systems.

Findings

Correlation between X-ray and radio emissions in black hole systems

Evidence supporting a unified disk-jet coupling mechanism

Differences and similarities between stellar-mass and supermassive black holes

Abstract

In this chapter I will review the status of our phenomenological understanding of the relation between accretion and outflows in accreting black hole systems. This understanding arises primarily from observing the relation between X-ray and longer wavelength (infrared, radio) emission. The view is necessarily a biased one, beginning with observations of X-ray binary systems, and attempting to see if they match with the general observational properties of active galactic nuclei.
