ABELL3571_S
We propose three pointing observations of A3571: a south-pointing (S, 130 ks) to cover the southern cold front, a north-pointing (N, 110 ks) to include the northern jump in the surface brightness, and east pointing (E, 40 ks). This cluster does not exhibit signs of a cool core, presenting a unique opportunity to explore the influence of sloshing motions, avoiding the complexities associated with active galactic nuclei. We aim to investigate the thermodynamic properties of A3571's core regions by analyzing gas motions, temperature, and metal abundance distributions. Additionally, we plan to measure the Ni/Fe ratio to study the progenitor population of SN Ia.
