The role of large-scale magnetic field in the morphology and evolution of extragalactic radio sources

TL;DR

This paper explores how large-scale dipolar magnetic fields influence the formation, morphology, and evolution of extragalactic radio sources, supported by statistical analysis of over 500 sources.

Contribution

It introduces a model linking dipolar magnetic fields to radio source morphology and provides statistical correlations based on extensive observational data.

Findings

Correlation between magnetic field orientation and radio source morphology

Statistical relationships among physical parameters of radio sources

Support for magnetic field influence on source evolution

Abstract

We discuss a model of formation of extragalactic radio sources when the parent optical galaxy has a large-scale dipolar magnetic field. The study of dynamics of ejected from the central part of optical galaxy clouds of relativistic particles in dipolar magnetic field gives a possibility to explain main morphological features and physical properties of formed extragalactic radio sources. We bring some results of statistical analyses and correlations between physical parameters for more than 500 radio sources. In appendix we present the data of all used extragalactic radio sources with the references for them.
