项目摘要
The X-ray Group at the Institute of Astronomy has analysed and interpreted data from most cosmic X-ray telescopes and instruments. This grant application is to renew the rolling grant for its support. Over the next five years we shall pursue a programme of research centred on accreting black holes and clusters of galaxies. The most luminous non-explosive sources in the Universe are active galaxies and quasars, which are powered by an accreting black hole. Most of the X-ray emission from these objects originates close to the black hole where gravity is very strong. This causes high velocities and large redshifts, both doppler and gravitational, as well as strong bending of light. The emission spectrum from matter at the innermost radii is consequently highly distorted in a manner first discovered by us and which is easily recognised. We propose to measure these relativistic distortion using both the X-ray spectrum and its variability. The results can then be used to determine the geometry of the accretion flow and the source of the X-ray continuum. Through the location of the innermost orbit, we shall measure the spin of the black hole. The energy produced by a central massive black hole can have a profound effect on its host galaxy. This can be vividly observed when the galaxy is at the centre of a group or cluster of galaxies and the energy is emitted through jets. X-ray images show bubbles filled with relativitic plasma inflating and rising through the surrounding gas. Concentric ripples show energy flowing away from the bubbles in giant sound waves discovered by us and which dissipate heating the surrounding gas. The energy transferred in this way stops much of the gas from cooling rapidly and forming massive amounts of new stars. Filaments of cold gas are dragged around by the bubbles so marking the velocity field of the cluster core. We shall analyse and interpret X-ray and longer wavelength observations of the cores of groups and clusters in order to understand this important galaxy feedback process, including how and when a heating/cooling balance is established, how much cooling and star formation takes place and how much it applies to the formation of all massive galaxies. Funding for Postdoctoral Research Assistants to work on these exciting and fundamental topics in astrophysics is sought for a five year programme.
天文学研究所的X射线小组分析和解释了来自大多数宇宙X射线望远镜和仪器的数据。此拨款申请是为了更新其支持的滚动拨款。在今后五年中,我们将开展一项以吸积黑洞和星系团为中心的研究方案。宇宙中最明亮的非爆炸源是活跃的星系和类星体,它们由吸积黑洞提供动力。这些物体的大部分X射线发射都起源于黑洞附近,那里的引力非常强。这导致了高速度和大的红移,包括多普勒和引力,以及光的强烈弯曲。因此,物质在最内层半径处的发射光谱以我们首先发现的方式高度扭曲,并且很容易识别。我们建议使用X射线光谱及其可变性来测量这些相对论性失真。结果可以用来确定吸积流的几何形状和X射线连续谱的来源。通过最内层轨道的位置,我们将测量黑洞的自旋。中心大质量黑洞产生的能量可以对其宿主星系产生深远的影响。当星系位于星系群或星系团的中心时,可以生动地观察到这一点,并且能量是通过喷流发射的。X射线图像显示,充满相对论等离子体的气泡在周围气体中膨胀并上升。同心圆波纹显示了我们发现的巨大声波中的能量从气泡中流出,并消散了周围气体的热量。以这种方式传递的能量阻止了大部分气体迅速冷却并形成大量的新恒星。冷气体的细丝被气泡拖来拖去,从而标记了星系团核心的速度场。我们将分析和解释对星系团和星系团核心的X射线和较长波长观测,以了解这一重要的星系反馈过程,包括如何以及何时建立加热/冷却平衡,发生多少冷却和星星形成,以及它在多大程度上适用于所有大质量星系的形成。资助博士后研究助理在天体物理学这些令人兴奋的和基本的主题工作是寻求一个为期五年的计划。
