摘要：
遥远星系的自转速度，当被解释为一个大小（光度）指标时，可以作为一种工具来选择高红移标准棒（蜡烛）和探测世界模型和星系演化通过经典的角直径红移或哈勃图测试。我们实施了建议的测试策略，使用的样本30个旋转器跨越红移范围0.2<z<1的高分辨率光谱和图像获得的VIMOS/VLT深红移巡天（VVDS）和大天文台起源深巡天（GOODs）。我们表明，通过应用在同一时间的角直径红移和哈勃图相同的样本的对象（即速度选择星系盘），可以得到一个特征图，宇宙学演化图，映射全球宇宙学参数和局部结构参数的光盘，如大小和光度之间的关系。这个图表允许把宇宙学参数的约束条件时，一般盘演化的先验信息是可用的。特别是，通过假设同样旋转的大圆盘在z=1时的亮度不会比现在低（M（z=1）< M（0）），我们发现在2 σ的置信水平下排除了扁平物质主导的宇宙学（Omega_m=1），在大于1 σ的置信水平下排除了低质量密度的开放宇宙学（Omega_m = 0.3）和没有暗能量贡献。因此，通过假设宇宙学模型的先验知识，宇宙学演化图可以用来获得关于质量几乎相等的暗物质晕中重子盘结构参数红移演化的有用见解。
英文摘要：
The rotational velocity of distant galaxies, when interpreted as a size (luminosity) indicator, may be used as a tool to select high redshift standard rods (candles) and probe world models and galaxy evolution via the classical angular diameter-redshift or Hubble diagram tests. We implement the proposed testing strategy using a sample of 30 rotators spanning the redshift range 0.2<z<1 with high resolution spectra and images obtained by the VIMOS/VLT Deep Redshift Survey (VVDS) and the Great Observatories Origins Deep Survey (GOODs). We show that by applying at the same time the angular diameter-redshift and Hubble diagrams to the same sample of objects (i.e. velocity selected galactic discs) one can derive a characteristic chart, the cosmology-evolution diagram, mapping the relation between global cosmological parameters and local structural parameters of discs such as size and luminosity. This chart allows to put constraints on cosmological parameters when general prior information about discs evolution is available. In particular, by assuming that equally rotating large discs cannot be less luminous at z=1 than at present (M(z=1) < M(0)), we find that a flat matter dominated cosmology (Omega_m=1) is excluded at a confidence level of 2sigma and an open cosmology with low mass density (Omega_m = 0.3) and no dark energy contribution is excluded at a confidence level greater than 1 sigma. Inversely, by assuming prior knowledge about the cosmological model, the cosmology-evolution diagram can be used to gain useful insights about the redshift evolution of the structural parameters of baryonic discs hosted in dark matter halos of nearly equal masses.
