宇宙学家经常使用计算机模拟生成星系的合成宇宙。此类目录在分析和利用当前和即将进行的星系巡天中发挥着重要作用。我回顾了生成合成或“模拟”目录的不同方式，并讨论了模型试图遵循的不同物理过程，解释了为什么在尝试打造宇宙时尽可能现实很重要。
Cosmologists regularly generate synthetic universes of galaxies using computer simulations. Such catalogues have an essential role to play in the analysis and exploitation of current and forthcoming galaxy surveys. I review the different ways in which synthetic or ‘mock’ catalogues are produced and discuss the different physical processes that the models attempt to follow, explaining why it is important to be as realistic as possible when trying to forge the Universe.
