We present the Sejong Suite , an extensive collection of state-of-the-art high-resolution cosmological hydrodynamical simulations spanning a variety of cosmological and astrophysical parameters, primarily developed for modeling the Ly α forest. The suite is organized into three main categories ( Grid Suite , Supporting Suite , and Systematics Suite ), addressing different science targets. Adopting a particle-based implementation, we follow the evolution of gas, dark matter (cold and warm), massive neutrinos, and dark radiation, and consider several combinations of box sizes and number of particles. With additional enhancing techniques, we are able to reach an equivalent resolution up to 3 × 3328 3 = 110 billion particles in a (100 h −1 Mpc) 3 box size, ideal for current and future surveys (e.g., Extended Baryon Oscillation Spectroscopic Survey and Dark Energy Spectroscopic Instrument). Noticeably, for the first ti...

世宗套房：大规模中微子，暗辐射和温暖暗物质的宇宙流体力学模拟

我们展示了世宗套房，它是广泛收集的最新的高分辨率宇宙学水动力模拟的基础，它涵盖了各种宇宙学和天体物理参数，主要是为对Lyα森林建模而开发的。该套件分为三个主要类别（Grid Suite，Supporting Suite和Systematics Suite），以解决不同的科学目标。采用基于粒子的实现，我们跟踪气体，暗物质（冷的和温暖的），大量的中微子和暗辐射的演化，并考虑盒子大小和粒子数的几种组合。借助其他增强技术，我们可以在（100 h -1 Mpc）3的盒子中达到3×3328 3 = 1100亿个颗粒的等效分辨率，非常适合当前和将来的调查（例如，扩展的重子振荡光谱测量和暗能量光谱仪）。值得注意的是，第一个...
