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".

职业：暗物质和黑洞，解构星系。德克萨斯大学奥斯汀分校的卡尔·格布哈特（Karl Gebhardt）将开展一项观测计划，研究银河系研究的两个领域。研究的第一部分涉及位于星系中心的超大质量黑洞。该研究的目标是调查球状星团中黑洞的存在，并研究具有已知最大黑洞的大质量星系的特性。这项工作的目的是允许对进化模型进行严格的测试，这些模型可以预测黑洞与其宿主星系的特性之间的相关性，也可以更好地确定黑洞是如何生长的。第二项努力涉及对星系暗物质晕的研究。目标是分析暗物质的轮廓，以提供整个给定星系的形状和恒星轨道特性。由于不同的形成过程会留下不同的遗迹特征，这些剖面应该能直接洞察星系的初始形成。这项研究将产生更广泛的影响，使公众能够立即和直接地看到结果。目标是使用一个网站来传播信息。黑洞研究尤其吸引公众，而拓展工作将利用这种兴趣来“教育和激发”。
