标题： Iron abundances in hydrodynamical simulations of galaxy clusters

摘要： 使用流体力学SPH模拟星系团来研究星系团内部介质的金属增丰。 根据数值分辨率和多个模型参数，确定了模拟星系团的最终金属丰度。 对于一组标准模型假设，模拟结果表明铁丰度与观测数据大致一致。 最终的X射线性质对ICM（星系团内部介质）加热不敏感。 这支持了一种情景，即冷团簇的ICM演化由辐射冷却驱动。 显示英文摘要

摘要： Hydrodynamical SPH simulations of galaxy clusters are used to investigate the metal enrichment of the intracluster medium. The final metallicity abundances of the simulated clusters are determined according to the numerical resolution and a number of model parameters. For a fiducial set of model prescriptions the results of the simulations indicate iron abundances in broad agreement with data. Final X-ray properties are not sensitive to the heating of the ICM. This supports a scenario where the ICM evolution of cool clusters is driven by radiative cooling.
