The gamma-ray properties of radio-selected extragalactic jets

TL;DR

This paper analyzes the gamma-ray characteristics of radio-selected extragalactic jets, comparing radio and gamma-ray data from VLBI observations to understand their emission mechanisms.

Contribution

It provides a comparative analysis of gamma-ray and radio properties of AGN jets from MOJAVE and TANAMI samples, including upper limits for undetected sources.

Findings

Radio and gamma-ray properties are correlated in AGN jets.

Upper limits set on gamma-ray flux for non-detected radio-bright sources.

Comparison enhances understanding of jet emission mechanisms.

Abstract

Most extragalactic jets in radio-loud Active Galactic Nuclei are bright and variable gamma-ray sources, which are continuously monitored with Fermi/LAT. We present the gamma-ray properties of the MOJAVE and TANAMI AGN samples of radio-loud AGN. Both programs provide properties of the parsec-scale radio jets using Very Long Baseline Interferometry (VLBI) techniques. This information is important to understand the broad-band emission mechanism of these sources. In this work we compare the radio and gamma -ray properties of the two samples and present upper limits on the gamma-ray flux of the radio-brightest jet sources not yet detected by Fermi/LAT.
