论文摘要
X射线积分场单元（X-IFU）在板载板上，第二个大ESA任务“雅典娜”将是高空间（5''）和光谱（2.5EV）分辨率X射线成像光谱仪，在0.2-12 KEV Energy Band中运行。它将通过宇宙中最大的物质，星系中最大的物质光环的宇宙时间来解决大会和进化的科学问题。为此，我们提出了一项持续的可行性研究，以证明在其地层时期揭示大量光环的物理学的X-IFU能力。从远处（z = 2）的星系（$ M_ {500} = 7 \ CDOT 10^{13} M_ \ ODOT/H $）从绣球界和流体动力学数值模拟中提取，我们进行了X-IFU观察的端到端模拟。从全局，1d和2d量的重建中，我们计划研究星系簇的各种X-IFU科学案例，例如群集内培养基（ICM）的化学富集，组和群集的动力组装以及银河系和超级物质黑洞的反馈影响。
The X-ray Integral Field Unit (X-IFU) on-board the second large ESA mission ''Athena'' will be a high spatial (5'') and spectral (2.5eV) resolution X-ray imaging spectrometer, operating in the 0.2-12 keV energy band. It will address the science question of the assembly and evolution through cosmic time of the largest halos of matter in the Universe, groups and clusters of galaxies. To this end, we present an on-going feasibility study to demonstrate the X-IFU capabilities to unveil the physics of massive halos at their epoch of formation. Starting from a distant (z=2) group of galaxies ($M_{500} = 7\cdot 10^{13} M_\odot/h$) extracted from the HYDRANGEA cosmological and hydrodynamical numerical simulations, we perform an end-to-end simulation of X-IFU observations. From the reconstruction of the global, 1D and 2D quantities, we plan to investigate the various X-IFU science cases for clusters of galaxies, such as the chemical enrichment of the intra-cluster medium (ICM), the dynamical assembly of groups and clusters and the impact of feedback from galaxy and super-massive black hole evolution.
