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）中一个特殊目标的发光椭圆星系亚样本，在大尺度上探测星系分布功率谱，研究大质量星系的演化。这个样本被称为“亮红星系样本”，由大约10万个红移为0.5的星系组成，并且被设计成低红移和高红移的星系应该具有相似的内在特性。目标是确定大尺度结构对物质、宇宙常数和空间曲率的低红移平衡的精度约束。这些结果将补充宇宙微波背景各向异性和遥远超新星的结果，并将对建立一个经过良好测试的宇宙学模型做出重大贡献。

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.
