z=0.14 ~ z=0.89的星系团的温度和铁丰度的径向关系
The Radial Dependence of Temperature and Iron Abundance: Galaxy Clusters from z=0.14 to z=0.89
摘要:
利用钱德拉和XMM-牛顿档案数据的35个星系团,我们测量的平均温度和金属丰度分布的集群的基础上分离的温度,冷却时间,和红移。我们的研究结果表明,没有证据表明,一旦考虑到这些选择效应的金属丰度或温度分布与红移的显着变化。
英文摘要:
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.
