项目摘要
AST-0506054Van ZeeDwarf galaxies are the building blocks of large galaxies and the most numerous galaxy type in the local Universe, and are therefore key constituents that provide unique insight into galaxy formation and evolution. This project is a comprehensive study of gaseous and stellar dynamics in low mass galaxies, to examine kinematic constraints on morphological evolution between the different dwarf galaxy classes, because it has been hypothesized that these classes simply represent different evolutionary states. The observations will exploit a relatively unexplored region of parameter space to investigate the feasibility of passive morphological transformation, specifically considering whether angular momentum regulates star formation activity, the role of environment in the initiation of a starburst phase, and the connection between low redshift dwarf galaxies and the rapidly evolving population of faint blue galaxies at intermediate redshift.This program will have a broad impact by advancing discovery while promoting teaching, training, and learning. A lot of the work will be carried out by graduate and undergraduate students as independent research projects, and the data will be incorporated into the classroom for intermediate level astronomy courses.
van zeeddwarf星系是大型星系的基石,也是本地宇宙中数量最多的星系类型,因此是提供星系形成和演化独特见解的关键组成部分。该项目是对低质量星系中气体和恒星动力学的综合研究,以检查不同矮星系类别之间形态演化的运动学约束,因为它已经假设这些类别只是代表不同的演化状态。观测将利用相对未开发的参数空间区域来研究被动形态转换的可行性,特别是考虑角动量是否调节恒星形成活动,环境在星爆阶段起始中的作用,以及低红移矮星系与中间红移快速演化的微弱蓝色星系群之间的联系。该项目将通过推进发现,同时促进教学、培训和学习,产生广泛的影响。许多工作将由研究生和本科生作为独立的研究项目进行,数据将被纳入中级天文学课程的课堂。
