AST-0507170INSTITUTION: University of Minnesota, Twin CitiesPI: Roberta HumphreysTITLE: Collaborative Research to Map the Asymmetric Thick DiskABSTRACTDr. Roberta Humpheys (University of Minnesota, Twin Cities), Dr. Juan Cabanela (St. Cloud State University) and Dr. Jeffrey Larsen (United States Naval Academy) will undertake a program of photometric and spectroscopic observations, as well as computer modeling, to map the so-called "asymmetric thick disk" and its kinematics in the inner part of the Galaxy. The intellectual goal of the research is to address several questions related to this structure, including its size, extent along our line of sight, and the degree of spatial and kinematic symmetry relative to the plane. This information will be used to test models for the origin of this asymmetry, which may involve a triaxial thick disk, a gravitational interaction with the Galactic bar in the disk, or the fossil remnant of a galaxy merger. The research will have broad impact through the involvement of undergraduate and graduate students, and by fostering close collaboration between a research extensive university, and two primarily undergraduate institutions.

AST-0507170机构：明尼苏达大学双城分校PI：Roberta Humphreys标题：绘制不对称厚盘的合作研究ABSTRACTDr. Roberta Humpheys（双子城明尼苏达大学）、Juan Cabanela博士（圣克劳德州立大学）和Jeffrey Larsen博士（美国海军学院）将进行光度和光谱观测方案以及计算机建模，绘制所谓的“不对称厚盘”及其在银河系内部的运动学。 这项研究的智力目标是解决与这个结构有关的几个问题，包括它的大小，沿着我们视线的范围，以及相对于平面的空间和运动对称程度。这些信息将被用来测试模型的起源，这种不对称性，这可能涉及一个三轴厚盘，引力相互作用与银河酒吧在磁盘中，或化石残骸的星系合并。 这项研究将通过本科生和研究生的参与，并通过促进研究广泛的大学和两个主要的本科院校之间的密切合作，产生广泛的影响。
