Iron in X-COP: tracing enrichment in cluster outskirts with high accuracy abundance profiles

Understand

We present the first metal abundance profiles for a representative sample of massive clusters.

• Our measures extend to $R_{500}$ and are corrected for a systematic error plaguing previous outskirt estimates.
• Our profiles flatten out at large radii, admittedly not a new result, however the radial range and representative nature of our sample extends its import well beyond previous findings.
• We find no evidence of segregation between cool-core and non-cool-core systems beyond $\sim 0.3 R_{500}$, implying that, as was found for thermodynamic properties (Ghirardini et al, 2019), the physical state of the core does not affect global cluster properties.
