The spectral energy distribution of gamma-faint compact radio sources

TL;DR

This study presents preliminary spectral energy distributions from radio to X-ray for six gamma-faint AGN, aiming to understand their high-energy behavior through combined VLBI and Swift observations.

Contribution

It provides the first detailed spectral energy distributions of gamma-faint AGN, enhancing understanding of their emission mechanisms and high-energy properties.

Findings

Spectral energy distributions show diverse high-energy characteristics.

Gamma-faint sources exhibit different X-ray to radio ratios.

Preliminary results suggest varied emission mechanisms among sources.

Abstract

MOJAVE is a VLBI program which monitors a statistically complete, radio-selected sample of 135 relativistically beamed, flat-spectrum active galactic nuclei for over more than a decade. In order to understand the high-energy behavior of this radio complete sample, we are performing Swift fill-in observations on the complete MOJAVE-I sample since 2007. The complete study of the spectral energy distribution from radio to X-ray bands on this radio-selected sample will provide us an opportunity to understand the nature of AGN. Here we present the preliminary results of the spectral energy distributions of six gamma-quiet or faint sources from this project: NRAO 140, PKS 0403-13, PKS B0422+004, PKS 0823+033, 3C 309.1, and 3C 380.
