论文摘要
欧几里得将观察到15 000摄氏度的最黑天空的$^2 $，在我们的银河系和太阳系中没有污染的区域中。覆盖40度$^2 $的三个“ Euclid Deep Fields”调查总共将把任务的科学范围扩展到高红移宇宙。完整的调查将由数十万个图像和数十个数据的数据构成。将观察到约100亿个来源。借助这些图像，欧几里得将探测宇宙的扩展历史和宇宙结构的演变。这将通过测量由于暗物质引力透镜引起的对星系形状的影响，并通过从测量的星系和星系星团的光谱红移中重建宇宙结构的三维分布。这些程序介绍了对这个前所未有的数据集的宇宙学和宇宙学约束的影响。特别令人感兴趣的是对暗能量性质的预期限制。
Euclid will observe 15 000 deg$^2$ of the darkest sky, in regions free of contamination by light from our Galaxy and our Solar System. Three "Euclid Deep Fields" surveys covering around 40 deg$^2$ in total will extend the scientific scope of the mission to the high-redshift Universe. The complete survey will be constituted by hundreds of thousands of images and several tens of petabytes of data. About 10 billion sources will be observed. With these images Euclid will probe the expansion history of the Universe and the evolution of cosmic structures. This will be achieved by measuring the effect on galaxy shapes due to dark matter gravitational lensing, and by reconstructing the three-dimensional distribution of cosmic structures from the measured spectroscopic redshifts of galaxies and clusters of galaxies. These proceedings present the implications for cosmology and cosmological constraints of this unprecedented data set. Of particular interest are the expected constraints on the nature of dark energy.
