Radio and Gamma Properties of the 2 cm Survey and MOJAVE Samples

TL;DR

This paper compares radio and gamma-ray properties of AGN samples from the 2 cm VLBA Survey and MOJAVE project, revealing higher gamma-ray detection rates in MOJAVE sources with faster jets and a preference for BL Lac objects.

Contribution

It provides a comparative analysis of gamma-ray detection rates between two well-defined AGN samples, highlighting the correlation with jet speed and object type.

Findings

MOJAVE sources have higher gamma-ray detection rates.

Faster jets correlate with increased gamma-ray detection.

BL Lac objects are more frequently detected in gamma-rays than QSOs.

Abstract

The 2 cm VLBA Survey observed since 1994 a set of ~170 Quasars, BL Lac objects, and radio galaxies, selected to be representative of the compact AGN radio population. This effort was continued as the MOJAVE project, where a statistically complete set of radio sources being monitored was defined. A comparison of the gamma-detection rates between the members of both samples shows that the MOJAVE-I sources, hosting generally faster jets, have a much higher detection rate than the sources not belonging to this sample. BL Lac objects are more favourably detected than QSOs in gamma-rays, in the same rate for both samples.
