Radiatively enhanced elasticity and turbulence in clumpy tori of Active Galactic Nuclei

TL;DR

This paper examines the impact of radiation forces on the dynamics of clumpy tori in Active Galactic Nuclei, highlighting the limitations of existing assumptions and proposing a more comprehensive perspective.

Contribution

It challenges previous models by considering clouds in all directions, showing that radiation forces nearly cancel out, which questions earlier theories on AGN torus dynamics.

Findings

Radiation forces are nearly canceled when clouds are in all directions.

Previous models assuming directional forces are inadequate.

The theory's limitations are demonstrated through this analysis.

Abstract

The paper assumes radiation forces proportional to distance between equal temperature clouds. However, we assume there are clouds in any direction. The forces then cancel almost entirely, besides small velocity effects. Therefore, the presented theory is inadequate.
