资源简介：
该数据集来自CAMELS磁流体动力学模拟的星系目录，它追踪了暗物质粒子和流体元素从红移z=127到z=0的演化过程。数据集包含了如三维位置、恒星质量、恒星半径、恒星金属丰度和最大圆周速度等特征。规模上，该数据集包含了1000个具有不同随机种子和宇宙学参数值的模拟。任务旨在实现对宇宙学模拟数据的一般化推广。
This dataset is sourced from the galaxy catalog of the CAMELS magnetohydrodynamic simulations, which tracks the evolution of dark matter particles and fluid elements from redshift z=127 to z=0. It includes various features such as 3D positions, stellar mass, stellar radius, stellar metallicity, and maximum circular velocity. In terms of scale, the dataset contains 1000 simulations with distinct random seeds and cosmological parameter values. The task is designed to enable generalizable adaptation to cosmological simulation data.
