Luminous Elliptical Galaxies in the Sloan Digital Sky Survey: Large-Scale Structure and Galaxy Evolution

本研究将利用斯隆数字巡天（SDSS）中的一个特殊目标的发光椭圆星系子样本，探测大尺度上的星系分布功率谱，并研究大质量星系的演化。 该样本被称为“亮红星系样本”，由大约10万个红移为0.5的星系组成，其设计目的是使低红移和高红移的星系具有相似的内在性质。 目标是确定大尺度结构对低红移物质平衡、宇宙学常数和空间曲率的精确约束。 这些结果将补充那些从宇宙微波背景各向异性和遥远的超新星，并应大大有助于建设一个良好的测试宇宙学模型。

This research will use a specially-targeted subsample of luminous elliptical galaxies in the Sloan Digital Sky Survey (SDSS) to probe the galaxy distribution power spectrum on large scales, and to study the evolution of massive galaxies. The sample is called the "Bright Red Galaxy Sample," consisting of roughly 100,000 galaxies out to a redshift of 0.5, and is designed so that galaxies at low and high redshift should have similar intrinsic properties. The goals are to determine precision constraints from large-scale structure on the low-redshift balance of matter, cosmological constant, and spatial curvature. These results will complement those from cosmic microwave background anisotropies and distant supernovae and should contribute substantially to the construction of a well-tested cosmological model.
