Jet/medium interactions at large scales

TL;DR

This paper models high-energy emissions from jet-medium interactions in galactic and extragalactic systems, combining hydrodynamical simulations with radiative processes to predict observable signals across multiple wavelengths.

Contribution

It introduces a comprehensive radiative model that includes relativistic electron injection at various shock regions and couples it with hydrodynamical simulations for both galactic and extragalactic jets.

Findings

Predicted fluxes vary with jet power, density, and source age.

Model results are compared with current radio, X-ray, and gamma-ray sensitivities.

Provides insights into observable signatures of jet-medium interactions.

Abstract

High energy emission can be produced in the interaction sites of both galactic and extragalactic jets with the surrounding medium. We have developed a radiative model that accounts for the continuous injection of relativistic electrons in the forward, reverse and recollimation shocks developed in the shell, cocoon and reconfinement interaction regions, respectively. We also performed hydrodynamical simulations to establish the physical properties in both galactic and extragalactic systems. The resulting non-thermal emission is studied assuming different values for the jet power, the external mass density and the source age for both FR I galaxies and galactic microquasars. The obtained fluxes are compared to current instrument sensitivities at radio, X-ray and gamma-ray bands.
