The Dynamics of Radio Galaxies and Double-Double Radio Galaxies

TL;DR

This paper explores the physical processes and environmental interactions of radio galaxies and double-double radio galaxies, combining radio, X-ray, and thermal emission data to understand their dynamics.

Contribution

It provides a comprehensive analysis of the emission mechanisms and environmental factors influencing the evolution of radio galaxies and double-double radio galaxies.

Findings

Radio lobes emit synchrotron and inverse-Compton radiation.

Thermal environment around radio galaxies emits X-rays via bremsstrahlung.

Combined data allows measurement of physical conditions and dynamics.

Abstract

Relativistic and magnetised plasma ejected by radio loud AGNs through jets form the diffuse lobes of radio galaxies. The radiating particles (electron/electron-positron) in lobes emit in radio via the synchrotron process and X-ray via inverse-Compton scattering of cosmic microwave background photons. The thermal environment around radio galaxies emits X-rays via the thermal bremsstrahlung process. By combining information from these processes we can measure physical conditions in and around the radio lobes and thus study the dynamics of radio galaxies, including double-double radio galaxies.
