论文摘要
大型星系簇的光谱调查揭示了淡淡的背景星系的特性，这要归功于强烈的重力透镜提供的放大倍率。我们对12个大型群集的整体光谱观测进行了系统分析，该观测值是通过多单元光谱探索器（MUSE）进行的。所有数据均在非常好的观察条件下（0.6英寸）在每个指向的有效暴露时间（0.6英寸）下，总计125小时。我们的观察结果涵盖了〜23 arcmin $^2 $在群集方向上的总体固体角度，其中许多以前是由Mac，Frontier Fields，Achastier Excection in faction inter Limit of Ach floction fort of Ach floction fort。 （0.77--1.5）$ \ times $ 10 $^{ - 18} $ erg \，s $^{ - 1} $ \，CM $^{ - 2} $7000Å，我们提出了我们开发的策略，以减少这些观察数据，以降低这些观察数据，以确定我们的固定量，并确定一个强度的量子。 312个产生939个多个图像的镜头。最终的红移目录包含3300多个可靠的红移，其中40 \％用于群集成员，$ \ sim $ 30 \％\％的镜头lyman- $ $ $ $ $ lyman-$α$ emitters nim sim emitters in Sims nim sim sim sim sim sim sim sim sim bess $ bess $ abt inf the $ abt y。我们发现，在高磁化方案中的镜头分布（$μ{=} $ 2--25）遵循$ n（z）\proptoμ^{ - 2} $的理论期望这项工作的完整数据产品可供社区[删节]。
Spectroscopic surveys of massive galaxy clusters reveal the properties of faint background galaxies, thanks to the magnification provided by strong gravitational lensing. We present a systematic analysis of integral-field-spectroscopy observations of 12 massive clusters, conducted with the Multi Unit Spectroscopic Explorer (MUSE). All data were taken under very good seeing conditions (0.6") in effective exposure times between two and 15 hrs per pointing, for a total of 125 hrs. Our observations cover a total solid angle of ~23 arcmin$^2$ in the direction of clusters, many of which were previously studied by the MACS, Frontier Fields, GLASS and CLASH programs. The achieved emission line detection limit at 5$σ$ for a point source varies between (0.77--1.5)$\times$10$^{-18}$ erg\,s$^{-1}$\,cm$^{-2}$ at 7000Å. We present our developed strategy to reduce these observational data, detect sources and determine their redshifts. We construct robust mass models for each cluster to further confirm our redshift measurements using strong-lensing constraints, and identify a total of 312 strongly lensed sources producing 939 multiple images. The final redshift catalogs contain more than 3300 robust redshifts, of which 40\% are for cluster members and $\sim$30\% for lensed Lyman-$α$ emitters. 14\% of all sources are line emitters not seen in the available HST images, even at the depth of the FFs ($\sim29$ AB). We find that the magnification distribution of the lensed sources in the high-magnification regime ($μ{=}$ 2--25) follows the theoretical expectation of $N(z)\proptoμ^{-2}$. The quality of this dataset, number of lensed sources, and number of strong-lensing constraints enables detailed studies of the physical properties of both the lensing cluster and the background galaxies. The full data products from this work are made available to the community. [abridged]
