Hybrid morphology radio sources - follow-up VLBA observations

TL;DR

This paper reports high-resolution VLBA follow-up observations of rare hybrid radio sources exhibiting both FR I and FR II morphologies, providing insights into their nature and the FR classification division.

Contribution

It presents new VLBA observations of five hybrid sources, suggesting they are FR II objects evolving in non-uniform high-density environments.

Findings

Hybrid sources are likely FR II objects with asymmetric environments.

High-resolution imaging reveals detailed jet structures.

Supports the idea that environment influences FR morphology.

Abstract

Hybrid sources that present FR I - like jet on the one side of the radio core and FR II - like on the other are rare class of objects that may posses key to understanding the origin of FR division. We presents information connected with the new high resolution VLBA follow-up observations of 5 recently discovered hybrid sources. We believe that sources which exhibit two different morphologies at the opposite side of the radio core are FR II type objects evolving in non-uniform high-density environment.
