Powerful extragalactic jets dissipate their kinetic energy far from the central black hole

A. L. W. Harvey, M. Georganopoulos, et al.

Discover groundbreaking insights into the energy dissipation mechanisms of relativistic plasma jets in active galactic nuclei. This research, conducted by Adam Leah W. Harvey, Markos Georganopoulos, and Eileen T. Meyer, reveals that the molecular torus, positioned about 1 parsec from supermassive black holes, plays a pivotal role in gamma-ray emissions. A must-hear for astrophysics enthusiasts!

Abstract
Accretion onto supermassive black holes in some active galactic nuclei (AGN) drives relativistic plasma jets, dissipating a significant portion of their kinetic energy into gamma-ray radiation. This paper investigates the location of this energy dissipation, using a novel diagnostic called the "seed factor." Analyzing 62 multiwavelength spectral energy distributions of gamma-ray quasars, the study finds that the molecular torus, located approximately 1 parsec from the black hole, is the dominant location for energy dissipation in powerful jets.
