Radio Properties of the $γ$-ray Emitting CSO Candidate 2234+282

Abstract: Most of the gamma-ray emitting active galactic nuclei (AGN) are blazars, although there is still a small fraction of non-blazar AGN in the Fermi/LAT catalog. Among these misaligned gamma-ray-emitting AGN, a few can be classified as Compact Symmetric Objects (CSOs). In contrast to blazars in which gamma-ray emission is generally thought to originate from highly beamed relativistic jets, the source of gamma-ray emission in unbeamed CSOs remains an open question. The rarity of the gamma-ray emitting CSOs is a mystery as well. Here we present the radio properties of the gamma-ray CSO candidate 2234+282.
