SDSS 与重子振荡光谱巡天 (BOSS) 的多目标光纤光谱仪
摘要
我们介绍了斯隆数字巡天 (SDSS) 的多目标光纤光谱仪的设计与性能,以及为重子振荡光谱巡天 (BOSS) 所做的升级。该光谱仪最初于 1999 年秋季在阿帕奇点天文台的 2.5 米口径斯隆望远镜上投入使用,为 SDSS 和 SDSS-II 巡天产生了超过 150 万条光谱,推动了包括 2005 年首次观测到重子声学振荡在内的各种银河系及河外科学研究。光谱仪于 2009 年完成升级,目前用于第三代 SDSS-III 项目的旗舰巡天 BOSS。BOSS 将在 10,000 平方度的天区内测量 135 万个红移达 0.7 的大质量星系的红移,以及 16 万个高红移类星体的莱曼阿尔法吸收,从而对宇宙的绝对宇宙距离尺度进行百分之一水平的测量,并对暗能量状态方程施加严格约束。这对双多目标光纤光谱仪采用了简单的光学布局,包含反射式准直镜、光栅、全折射相机和最先进的 CCD 探测器,可在覆盖近紫外至近红外的通带内,通过两个通道同时产生数百条光谱,分辨本领 R = /FWHM ~ 2000。秉承成熟的传统,光谱仪为 BOSS 进行了升级,采用了体相位全息光栅和现代 CCD 探测器,使峰值吞吐率提高了近一倍,通带扩展至 360 < < 1000 nm,并将每次曝光的光纤数量从 640 根增加到 1000 根。本文描述了原始的 SDSS 光谱仪设计以及为 BOSS 实施的升级,并记录了预测和实测的性能。
