标题： The HalfDome Multi-Survey Cosmological Simulations: N-body Simulations

摘要： 即将进行的宇宙学调查有可能在多个领域取得突破性发现，包括中微子质量、暗能量和暴胀。 大多数关键科学目标需要对来自多个调查的数据集进行联合分析，以打破参数简并并校准系统误差。 要实现这样的分析，需要一组能够现实模拟相关可观测量的模拟数据。 在本文中，我们介绍了HalfDome宇宙学模拟的N体部分，该模拟专为Stage-IV宇宙学调查的联合分析而设计，如Rubin LSST、Euclid、SPHEREx、Roman、DESI、PFS、Simons Observatory、CMB-S4和LiteBIRD。 我们的初始数据发布包含300TB的数据，包括从$z$=0--4之间的全天空光锥和晕族目录，针对11个固定宇宙学现实情况，以及一个具有局部原初非高斯性（$f_{\rm NL}$=20）的额外运行。 这些模拟在3.75$\,h^{-1} {\rm Gpc}$的盒子中演化$6144^3$个粒子，达到最小晕质量$\sim 6 \times 10^{12}\,h^{-1} M_\odot$和最大尺度$k \sim 1\,h{\rm Mpc}^{-1}$。 访问数据的说明以及未来数据发布的计划，请参见https://halfdomesims.github.io。 显示英文摘要

摘要： Upcoming cosmological surveys have the potential to reach groundbreaking discoveries on multiple fronts, including the neutrino mass, dark energy, and inflation. Most of the key science goals require the joint analysis of datasets from multiple surveys to break parameter degeneracies and calibrate systematics. To realize such analyses, a large set of mock simulations that realistically model correlated observables is required. In this paper we present the N-body component of the HalfDome cosmological simulations, designed for the joint analysis of Stage-IV cosmological surveys, such as Rubin LSST, Euclid, SPHEREx, Roman, DESI, PFS, Simons Observatory, CMB-S4, and LiteBIRD. Our 300TB initial data release includes full-sky lightcones and halo catalogs between $z$=0--4 for 11 fixed cosmology realizations, as well as an additional run with local primordial non-Gaussianity ($f_{\rm NL}$=20). The simulations evolve $6144^3$ particles in a 3.75$\,h^{-1} {\rm Gpc}$ box, reaching a minimum halo mass of $\sim 6 \times 10^{12}\,h^{-1} M_\odot$ and maximum scale of $k \sim 1\,h{\rm Mpc}^{-1}$.
