Abstract

ABSTRACT The analysis of the elemental abundances in galaxy clusters offers valuable insights into the formation and evolution of galaxies. In this study, we explore the chemical enrichment of the intracluster medium in the Ophiuchus cluster by utilizing XMM–Newton EPIC-pn observations. We explore the radial profiles of Si, S, Ar, Ca, and Fe. Due to the high absorption of the system, we have obtained only upper limits for O, Ne, Mg, and Ni. We model the X/Fe ratio profiles with a linear combination of core-collapse supernovae (SNcc) and Type Ia supernovae (SNIa) models. We found a flat radial distribution of SNIa ratio over the total cluster enrichment $10\!-\!30{{\ \rm per\ cent}}$ for all radii. However, the absence of light α-elements abundances may lead to overestimation of the SNcc contribution.
