BigBOSS 实验
摘要
BigBOSS 是一项第四代地基暗能量实验，旨在通过覆盖 14,000 平方度的广域星系和类星体红移巡天，研究重子声学振荡 (BAO) 和结构增长。该实验已获得美国国家光学天文台 (NOAO) 的有条件批准，以响应为基特峰 4 米 Mayall 望远镜配备重大新仪器和高影响力科学项目的征集。BigBOSS 仪器是一个机器人驱动、光纤馈电的光谱仪，能够在 340 nm 至 1060 nm 的波长范围内同时获取 5000 条光谱，分辨率 R = 3000-4800。利用已在进行中的成像巡天数据，选择追踪底层暗物质分布的光谱目标。具体而言，目标包括红移高达 z = 1.0 的亮红星系 (LRG)，从而在红移和巡天面积上扩展了 BOSS LRG 巡天。为了探测更高红移的宇宙，BigBOSS 将瞄准红移高达 z = 1.7 的明亮 [OII] 发射线星系 (ELG)。总共将获取 2000 万个星系红移，以测量 BAO 特征、追踪较小尺度上的物质功率谱，并探测红移空间畸变。通过测量超过 600,000 个 2.2 < z < 3.5 类星体光谱中的 Ly-α 森林，BigBOSS 将为早期暗能量和宇宙曲率提供额外约束。结合 BigBOSS 类星体光谱中 Ly-α 森林的宽带功率分析，BigBOSS 星系 BAO 测量在 Planck 加上第三阶段先验条件下实现了 395 的品质因数 (FOM)。该 FOM 基于对宽带功率分析的保守假设 (kmax = 0.15)，如果当前工作允许我们将分析推进到更高波数 (kmax = 0.3)，则可能增长到超过 600。BigBOSS 还将对修正引力和暴胀理论施加约束，并以 0.024 eV 的精度测量中微子质量之和。
