Raining in MKW 3 s: A Chandra-MUSE Analysis of X-Ray Cold Filaments around 3CR 318.1

Abstract We present the analysis of X-ray and optical observations gas filaments observed in radio source 3CR 318.1, associated with NGC 5920, brightest cluster galaxy (BCG) MKW 3 s, a nearby cool core cluster. This work is one first analyses clusters carried out using MUSE observations. aim at identifying main excitation processes responsible for emission arising from these filaments. complemented VLT/MUSE observations, tracing colder phase, Chandra hotter highly ionized phase. Using we studied line intensity ratios along to constrain physical driving excitation, and, spectral found spatial association between morphology filaments, which are have lower metal abundance than surrounding intracluster medium (ICM), as already seen other BCGs. Comparing previous results literature BCGs, propose that process most likely combination star formation shocks, contribution self-ionizing, cooling ICM. Additionally, conclude originated AGN-driven outflows direction jet.
