Probing The Central Engines Of Low-Luminosity Active Galactic Nuclei

Abstract

I give a brief review of the observational properties of low-luminosity AGNs (LLAGNs). I outline some unresolved issues in the study of LLAGNs, emphasizing the uncertainties in the role of the truncated thin accretion disk, the dusty obscuring torus and the origin of high-energy radiation (X-rays and gamma-rays). I discuss key future directions for progress, focusing on the broadband multiwavelength observations that will help us address these issues and the importance of high-resolution infrared observations.
