Using radio jets of PKS J0334-3900 to probe the intra-cluster medium in A3135

TL;DR

This study uses multi-wavelength radio observations and simulations of PKS J0334-3900 to investigate how its morphology reveals the dynamics of the intra-cluster medium in Abell 3135.

Contribution

It introduces a detailed analysis and simulation linking radio galaxy morphology to ICM wind, orbital motion, and black hole precession, providing new insights into galaxy-cluster interactions.

Findings

Radio morphology consistent with ICM wind and orbital motion

Spectral indices constrain galaxy's dynamical history

Simulation reproduces observed radio features

Abstract

We present a multi-wavelength study of the radio galaxy PKS J0334-3900, which resides at the centre of Abell 3135. Using Australia Telescope Compact Array (ATCA) observations at 1.4, 2.5, 4.6 & 8.6 GHz, we performed a detailed analysis of PKS J0334-3900. The morphology and spectral indices give physical parameters that constrain the dynamical history of the galaxy, which we use to produce a simulation of PKS J0334-3900. This simulation shows that the morphology can be generated by a wind in the intracluster medium (ICM), orbital motion caused by a companion galaxy, and precession of the black hole (BH).
