论文摘要
通过理论和仿真知识的成像和光谱样品的联合研究为宇宙学模型的综合测试提供了Z <1.5的综合测试。这些红移的光谱星系样品可以至少在计划的暗能量光谱仪器(DESI)程序之外增加,至少以数量级的顺序,因此为这些关节研究提供了更大的约束功率。在2020年代后半及以后对这些星系的光谱观察将利用该制度的理论和模拟工作。反过来,这些高密度观察将允许增强对暗能量的测试,超出标准模型的物理和中微子质量,这些测试将大大超过当前可能的测试。在这里,我们提出了一个协调的模拟计划,理论建模和未来光谱学计划,该计划将在加速时期实现精确的宇宙学研究,其中最明显的是暗能量的影响。
Joint studies of imaging and spectroscopic samples, informed by theory and simulations, offer the potential for comprehensive tests of the cosmological model over redshifts z<1.5. Spectroscopic galaxy samples at these redshifts can be increased beyond the planned Dark Energy Spectroscopic Instrument (DESI) program by at least an order of magnitude, thus offering significantly more constraining power for these joint studies. Spectroscopic observations of these galaxies in the latter half of the 2020's and beyond would leverage the theory and simulation effort in this regime. In turn, these high density observations will allow enhanced tests of dark energy, physics beyond the standard model, and neutrino masses that will greatly exceed what is currently possible. Here, we present a coordinated program of simulations, theoretical modeling, and future spectroscopy that would enable precise cosmological studies in the accelerating epoch where the effects of dark energy are most apparent.
