CAREER: THE FORMATION AND EVOLUTION OF DISK GALAXIES

职业：盘状星系的形成与演化[j]。新墨西哥州立大学的Nicole Vogt将承担一项为期五年的观测和建模计划，以量化盘状星系的形成和演化。凯克望远镜和哈勃太空望远镜观测了150个遥远螺旋星系的样本，为该计划奠定了基础。这些数据将用于整合观测和理论工作，以了解星系的演化，如下：(1)选择效应将通过使用半解析模型来创建模型星系的集合来表征，(2)动力质量将与恒星质量相结合来研究凸起的演化，(3)双子座望远镜将用于绘制遥远螺旋子集的全盘旋转。光谱将用于测试对整个光晕的气体温度和分布的预测。总的来说，这些努力将探索如何调和观测到的高红移星系群与当地宇宙中发现的星系群。该提案还包含四个组成部分，旨在扩大在种族和地理上代表性不足的群体对科学的参与，使学生和教师与职业科学家进行对话，并在整个天文学界宣传研究工具。(1)将通过创建一个用于公开演讲的研究型教育材料数据库来重组对当地学校的天文学宣传。与研究生合作，发展适合与初中生和高中生互动的演讲风格，并加强主持教师和访问演讲者之间的互动。(2)发展天文学本科远程教育项目，提高代表性不足的民族和地域群体接受高等教育的机会。(3)将对两个用于星系图像分析的软件包进行严格比较，并向社会发布。(4)研究生和本科生将参与研究、教学和推广的各个方面，提供现代天文学和天体物理学的实践经验。

CAREER: The Formation and Evolution of Disk GalaxiesABSTRACTAST 0349155 VogtDr. Nicole Vogt, at the New Mexico State University, will undertake a five-year observational and modeling program to quantify the formation and evolution of disk galaxies A sample of 150 distant spiral galaxies has been observed with the Keck Telescopes and the Hubble Space Telescope, to form the basis for this program. These data will be used to integrate observational and theoretical efforts to understand galaxy evolution, as follows (1) Selection effects will be characterized by using semi-analytical models to create ensembles of model galaxies, (2) Dynamical masses will be combined with stellar masses to study the evolution of bulges, (3) The Gemini Telescopes will be used to map full-disk rotation for a subset of the distant spirals, (4) Spectra will be used to test predictions for gas temperatures and distributions throughout the halos. Taken together, these efforts will explore how to reconcile the observed galaxy populations at high redshifts with those found in the local universe.This proposal also contains four components designed to broaden the participation in science of ethnically and geographically underrepresented groups, to engage students and teachers in dialog with career scientists, and to propagate research tools throughout the astronomical community (1) Astronomy outreach to local schools will be restructured by creating a database of research-based educational materials for public talks, working with graduate students to develop presentation styles appropriate for interacting with middle and high school students, and strengthening interactions between host teachers and visiting speakers. (2) A distance education program will be developed in undergraduate astronomy, to improve access to higher education for underrepresented ethnic and geographic groups. (3) A rigorous comparison of two software packages used in galaxy image analysis will be conducted and released to the community. (4) Graduate and undergraduate students will be involved in all aspects of research, teaching, and outreach, giving the hands-on experience in modern astronomy and astrophysics.
