Title

ESTIMATING THE SN IA ENRICHMENT AND GAS DYNAMICS IN THE CENTRAL REGION OF THE A2029 CLUSTER WITH XRISM

Abstract

The core region of A2029 is an excellent laboratory for estimating the Ni abundance because of a relatively hot intracluster medium (ICM) at roughly 6 keV, and constraining the contribution from Type Ia supernovae that are the monopoly manufacturer of Ni. Even though the A2029 center has two XRISM performance verification (PV) datasets, the total exposure is short (only 40 ks) and not enough to provide a strong constraint on the Ni abundance, particularly in the innermost core. Here, we suggest extending the PV observation data by doing a deep 100 ks observation of the A2029 core. This observation will reveal the Type Ia characteristics in A2029 with an accurate estimation of Ni. We will also show how AGN feedback and/or sloshing impact the dynamical evolution of the ICM.
