项目摘要

The completion of photometric and redshift surveys of large portions of the sky have revolutionized our understanding of faint galaxies, extending the category of dwarf galaxies to luminosities so faint that they blur the traditional distinction between galaxies and star clusters. At the same time, advances in computational cosmology have led to improved predictions of the properties of the smallest dark matter halos able to harbour luminous galaxies in the current paradigm of structure formation, the LCDM model. The confrontation of data with model predictions on these small objects holds the promise to validate or challenge the established paradigm on scales beyond those used to constrain its main parameters. The time is ripe for a concerted effort designed to assess the cosmological significance of Nature's smallest extragalactic objects. I propose to study this topic using a variety of observational and theoretical tools, from detailed N-body simulation of the formation of dark matter halos, to gasdynamical simulation of the formation of luminous dwarf galaxies, to direct observational efforts designed to survey the faintest galaxies in our Local Universe and to understand their impact on the formation of our Milky Way galaxy.
对大部分天空的光度测量和红移测量的完成彻底改变了我们对微弱星系的理解,将矮星系的类别扩展到亮度如此微弱以至于模糊了星系和星星团之间的传统区别。与此同时,计算宇宙学的进步导致了对最小暗物质晕的性质的改进预测,这些晕能够在当前的结构形成范式LCDM模型中容纳发光星系。这些小物体的数据与模型预测的对抗有望在超出用于限制其主要参数的尺度上验证或挑战已建立的范式。现在时机已经成熟,可以共同努力,评估自然界最小的河外天体的宇宙学意义。我建议使用各种观测和理论工具来研究这个主题,从详细的N体模拟暗物质晕的形成,到发光矮星系形成的气体动力学模拟,再到直接观测工作,旨在调查我们本地宇宙中最微弱的星系,并了解它们对我们银河系形成的影响。
