Kinematic Constraints on Dwarf Galaxy Evolution

AST-0506054 Van ZeeDwarf星系是大型星系的基石，也是本星系中数量最多的星系类型，因此是对星系形成和演化提供独特见解的关键组成部分。这个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之间对形态演化的运动学约束，因为已经假设这些类仅仅代表不同的演化状态。这些观测将利用一个相对未被探索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，环境在恒星爆发阶段的启动中的作用，以及低红移矮星系和快速演化的中等红移的淡蓝色星系之间的联系。这一计划将产生广泛的影响，促进发现，同时促进教学、培训和学习。许多工作将由研究生和本科生作为独立研究项目进行，数据将纳入中级天文学课程的课堂。

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.
