CAREER: Dark Matter and Black Holes, Deconstructing Galaxies

职业生涯：暗物质和黑洞，解构星系0349095卡尔·格哈德博士。德克萨斯大学奥斯汀分校的卡尔·格布哈特将实施一项观测研究计划，涉及银河系研究的两个领域。研究的第一部分涉及驻留在星系中的中央超大质量黑洞。这项研究的目的是调查球状星团中黑洞的存在，并研究拥有已知最大黑洞的大质量星系的性质。这项工作的目的是允许对预测黑洞与其所在星系的属性之间的相关性的演化模型进行严格的测试，并更好地确定黑洞是如何增长的。第二项工作涉及对星系暗物质晕的调查。其目标是分析暗物质的轮廓，提供给定星系的形状和恒星轨道属性。这些轮廓应该提供对星系最初形成的直接洞察，因为不同的形成过程留下不同的遗迹签名。这项研究的广泛影响将产生于扩展，让公众立即和直接地看到结果。目标是使用一个网站来传播信息。黑洞研究尤其吸引了公众，外展工作将利用这种兴趣来“教育和激发”。

CAREER: Dark Matter and Black Holes, Deconstructing GalaxiesABSTRACTAST 0349095 Karl GebhardtDr. Karl Gebhardt, at the University of Texas, Austin, will undertake an observational plan of research that addresses two areas of galactic research. The first part of the study involves the central supermassive black holes that reside in galaxies. The goal of the research is to investigate the existence of black holes in globular clusters and to study the properties of massive galaxies with the largest known black holes. The purpose of the work is to allow for stringent tests of evolutionary models that predict correlations between black holes and the properties of their host galaxies, and also to better ascertain how black holes grow. The second effort involves an investigation of galaxy dark matter halos. The goal is to analyze dark matter profiles, to provide both the shape and the stellar orbital properties throughout a given galaxy. These profiles should provide direct insight into the initial formation of the galaxy, since different formation processes leave different relic signatures.Broader impact of this research will result from outreach to allow the public to see the results immediately and directly. The goal is to use a website to disseminate the information. Black hole studies in particular fascinate the public, and the outreach effort will take advantage of that interest in order to "educate and excite".
