The Radial Dependence of Temperature and Iron Abundance: Galaxy Clusters from z=0.14 to z=0.89

TL;DR

This study analyzes temperature and iron abundance profiles in galaxy clusters across a range of redshifts, finding no significant evolution in these properties when accounting for selection effects.

Contribution

It provides a comprehensive analysis of radial temperature and metallicity profiles in galaxy clusters over a broad redshift range, highlighting the lack of significant evolution.

Findings

No significant change in metallicity profiles with redshift

Temperature profiles remain consistent across different redshifts

Profiles depend on cluster properties like temperature and cooling time

Abstract

Using archival Chandra and XMM-Newton data on 35 galaxy clusters, we measured average temperature and metallicity profiles for clusters based separated by temperature, cooling time, and redshift. Our results show no evidence for significant changes in the metallicity or temperature profiles with redshift once these selection effects are taken into account.
