在最初的两年里,我将在最亮的xmm -牛顿任务ULX光栅档案和新获得的观测数据中搜索来自超光x射线物体(ULX)的风,发布风探测结果并测试ULX预测的理论情景。我将利用高分辨率x射线光谱学的新技术。对ulx的光谱形状和变异性的分析也将有助于寻找中等质量黑洞候选者。接下来,我将比较ULX风能量学与由ULX和本地恒星形成驱动的光学星云的光度,以约束ULX反馈。我还将比较超爱丁顿吸积的理论模型与活动星系核(AGN)和活动星系核(ulx)中超快风(ufo)的物理特征,以了解活动星系核(AGN)和活动星系核(ulx)中不同的发射机制及其吸积速率。同时,我将使用各种x射线,光学和红外天文台研究AGN中的超大质量黑洞,以确定其变异性和遮挡的物理特性,并拓宽我对极端吸积的认识。此外,我将向xmm -牛顿、钱德拉和核之星x射线任务提交提案,并为新的ASTRO-H2任务(2020年)准备科学案例,取代强大但简短的Hitomi卫星,以前所未有的分辨率观测高能Fe K AGN和ULX ufo,并为非常大的欧洲和stfc资助的ATHENA任务准备科学案例。
英文摘要
During the first two years I will search for winds from Ultraluminous X-ray objects (ULX) in the brightest XMM-Newton mission ULX gratings archive and the newly awarded observations, publish the wind detections and test the theoretical scenarios predicted for ULXs. I will make use of novel techniques in high resolution X-ray spectroscopy. The analysis of the spectral shape and variability of ULXs will also enable the search for intermediate mass black hole candidates. Following this I will compare the ULX wind energetics with the luminosities of optical nebulae powered by ULXs and the local star formation to constrain ULX feedback. I will also compare theoretical models of super-Eddington accretion with physical characteristics of ultrafast winds (UFOs) in Active Galactic Nuclei (AGN) and ULXs to understand the different launching mechanisms in both AGN and ULXs and their accretion rates. Simultaneously, I will study supermassive black holes in AGN using various X-ray, optical and infrared observatories to determine the Physics of their variability and obscuration and broaden my knowledge of extreme accretion.Additionally, I am going to submit proposals to the XMM-Newton, Chandra and NuSTAR X-ray missions and prepare science cases for the new ASTRO-H2 mission (2020), replacing the powerful though brief Hitomi satellite, to observe the highly-energetic Fe K AGN and ULX UFOs with unprecedented resolution and prepare science cases for the very large European and STFC-funded ATHENA mission.
