Jet-Cloud Interactions in AGNs

TL;DR

This paper investigates how clouds in the broad-line region of active galactic nuclei interact with jets, producing high-energy emissions that could reveal details about the jet and surrounding gas.

Contribution

It presents a study of jet-cloud interactions in AGNs, focusing on high-energy emission near the jet base, which is a novel approach to probing the broad-line region.

Findings

High-energy emission from jet-cloud interactions may be detectable in nearby non-blazar sources.

The interaction provides insights into the structure of the broad-line region.

Detection of this emission can inform about jet properties and cloud characteristics.

Abstract

Active galactic nuclei present continuum and line emission. The former is produced by the accretion disk and the jets, whereas the latter is originated by gas located close to the super-massive black hole. The small region where the broad lines are emitted is called the broad-line region. The structure of this region is not well known, although it has been proposed that it may be formed by small and dense ionized clouds surrounding the supermassive black-hole. In this work, we study the interaction of one cloud from the broad line region with the jet of the active galactic nuclei. We explore the high-energy emission produced by this interaction close to the base of the jet. The resulting radiation may be detectable for nearby non-blazar sources as well as for powerful quasars, and its detection could give important information on the broad line region and the jet itself.
