"Supermassive black holes are now thought to lurk at the centres of most, if not all, galaxies but it is still unclear how these black holes form and what drives their subsequent growth over the history of the Universe. This project will focus on identifying growing black holes - seen as Active Galactic Nuclei (AGN; objects such as quasars and Seyferts) - and connecting the properties of these AGN with the properties of the galaxies they lie in. Will use the latest galaxy surveys, incorporating data from a wide range of facilities such as the Sloan Digital Sky Survey (SDSS) and the upcoming Legacy Survey of Space and Time (LSST) project to identify galaxies at different cosmic epochs and in different evolutionary states. Will then use multiwavelength datasets including X-ray survey data from ESA's XMM-Newton observatory and NASA's SWIFT and Chandra satellites, together with optical spectroscopy, infrared imaging and radio data, to identify AGN within these galaxies and determine their properties (such as their luminosities, black hole accretion rates, and their level of obscuration). Will track how the levels of AGN activity depend on the galaxy properties (such as mass, morphology and star formation history) to provide new insights into the processes fuelling and regulating black hole growth across the evolving galaxy population.

“超大质量黑洞现在被认为潜伏在大多数星系的中心，如果不是全部的话，但目前还不清楚这些黑洞是如何形成的，以及是什么推动了它们在宇宙历史上的后续增长。该项目将专注于识别不断增长的黑洞-被视为活动星系核（AGN;如类星体和Seyfert的对象）-并将这些AGN的属性与它们所在的星系的属性联系起来。 将使用最新的星系巡天，结合来自斯隆数字巡天（SDSS）和即将到来的时空遗产巡天（LSST）项目等各种设施的数据，以确定处于不同宇宙时代和不同进化状态的星系。然后将使用多波长数据集，包括来自ESA的XMM-牛顿天文台和NASA的SWIFT和Chandra卫星的X射线测量数据，以及光谱学，红外成像和无线电数据，以确定这些星系内的AGN并确定它们的属性（例如它们的光度，黑洞吸积率和它们的遮蔽程度）。将跟踪活动星系核的活动水平如何取决于星系的性质（如质量，形态和星星形成历史），以提供新的见解的过程中燃料和调节黑洞的增长在不断发展的星系人口。"
