Dust in Active Galactic Nuclei
Aigen Li
TL;DR
This review discusses the critical role of dust in active galactic nuclei, focusing on its extinction, infrared emission, composition, and size distribution, which are vital for understanding AGN unification.
Contribution
It provides a comprehensive summary of current knowledge on the properties and composition of circumnuclear dust in AGNs, highlighting recent advances.
Findings
Dust significantly affects AGN observations and models.
Infrared emission reveals dust composition and size distribution.
Understanding dust properties aids in unification theories of AGNs.
Abstract
Dust plays an essential role in the unification theory of active galactic nuclei (AGNs). This review summarizes our current understanding of the extinction and infrared emission properties of the circumnuclear dust in AGNs as well as the inferred dust composition and size distribution.
