A Rolling Grant for the Observation and Study of Cosmic X-ray Sources

天文学研究所的X射线天文学小组利用卫星（例如钱德拉、XMM-牛顿和ASTRO-E2）提供的数据研究星系团、活动星系和X射线背景的X射线特性、机制和演变。建议继续提供PPARC滚动赠款，核心工作人员保持在3.5个项目进展和成果评估年度不变。随着计算机任务的日益复杂，特别是空间和光谱分辨率（Chandra、XMM和ASTRO-E2）的大幅提高，需要增强计算能力。我期望更好地了解（a）黑洞通过相对论性铁线的运行;（B）星系团核心的冷却和加热过程;（c）星系团的气体含量;（d）从反射和吸收特征看黑洞吸积的环境;（e）大质量黑洞的模糊增长;（f）其他过程和宇宙物体。

The X-ray Astronomy group at the Institute of Astronomy researches the X-ray properties, mechanisms and evolution of clusters of galaxies, active galaxies and the X-ray background using data from satellites (e.g. Chandra, XMM-Newton and ASTRO-E2). It is proposed to continue the PPARC Rolling Grant with the core staff remaining constant at 3.5 PDRAs. The increasing sophistication of the computer tasks, particularly with the great increase in spatial and spectral resolution (Chandra, XMM and ASTRO-E2) requires enhancements in computing power. I anticipate a better understanding of (a) the operation of black holes through the relativistic iron line; (b) cooling and heating processes in cluster cores; (c) the gas content of clusters; (d) the environment of accreting black holes from reflection and absorption signatures; (e) the obscured growth of massive black holes; and (f) other processes and cosmic objects.
