ABELL_2199
As clusters are ultimate depositories of billions of core-collapse and Type Ia supernovae, measuring accurate abundances in the intracluster medium (ICM) provides unique constraints on the nature and physics of supernovae progenitors. While Resolve (in its GVC status) constrains the abundance of heavier elements (S, Ar, Ca, Cr, Mn, Fe, Ni), lighter elements (O, Ne, Mg, Si) can be constrained with XMM-Newton RGS and EPIC. Unlike other "abundance-friendly" clusters, Abell 2199 exhibits very weak EPIC-RGS abundance discrepancies. Our proposal takes advantage of this and aims for a 220 ks XRISM exposure of the core of A2199. Unleashing the full potential of join RGS-Resolve spectroscopy will boost our understanding of the nature of Type Ia supernovae progenitors and ICM enrichment.
