The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) began observations in July 2014. It pursues three core programs: APOGEE-2, MaNGA, and eBOSS. In addition, eBOSS contains two major subprograms: TDSS and SPIDERS. This paper describes the first data release from SDSS-IV, Data Release 13 (DR13), which contains new data, reanalysis of existing data sets and, like all SDSS data releases, is inclusive of previously released data. DR13 makes publicly available 1390 spatially resolved integral field unit observations of nearby galaxies from MaNGA, the first data released from this survey. It includes new observations from eBOSS, completing SEQUELS. In addition to targeting galaxies and quasars, SEQUELS also targeted variability-selected objects from TDSS and X-ray selected objects from SPIDERS. DR13 includes new reductions of the SDSS-III BOSS data, improving the spectrophotometric calibration and redshift classification. DR13 releases new reductions of the APOGEE-1 data from SDSS-III, with abundances of elements not previously included and improved stellar parameters for dwarf stars and cooler stars. For the SDSS imaging data, DR13 provides new, more robust and precise photometric calibrations. Several value-added catalogs are being released in tandem with DR13, in particular target catalogs relevant for eBOSS, TDSS, and SPIDERS, and an updated red-clump catalog for APOGEE. This paper describes the location and format of the data now publicly available, as well as providing references to the important technical papers that describe the targeting, observing, and data reduction. The SDSS website, http://www.sdss.org, provides links to the data, tutorials and examples of data access, and extensive documentation of the reduction and analysis procedures. DR13 is the first of a scheduled set that will contain new data and analyses from the planned ~6-year operations of SDSS-IV.
MaNGA: Mapping Nearby Galaxies at Apache Point Observatory
MANGA（Mapping Nearby Galerkin at APO）是第四代斯隆数字巡天（SDSS-IV）中的星系积分场光谱巡天。它将使用17个不同大小的纤维束，绘制10，000个附近星系中气体和恒星的成分和运动学。MaNGA的目标是为星系形成和演化提供新的见解，并为当前和未来的高红移研究提供本地基准。

The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment
第四代斯隆数字巡天（SDSS-IV）自2014年7月以来一直在运行。本文描述了该阶段的第二次数据发布，以及SDSS的第十四次数据发布（即数据发布14或DR 14）。本新闻稿公开了SDSS-IV在运行的前两年（2014年7月至2016年）采集的数据。与所有以前的SDSS版本一样，DR 14是累积的，包括SDSS自2000年第一阶段开始运行以来对所有数据的最新削减和校准。DR 14中的新内容是扩展重子振荡光谱调查（eBOSS）的第一次公开发布的数据;来自Apache Point Observatory（APO）星系演化实验第二阶段的第一批数据（APOGEE-2），包括来自被称为“大炮”的创新数据驱动机器学习算法的恒星参数估计;来自APO附近星系测绘（MaNGA）调查的数据立方体几乎是上一版本的两倍（总共N = 2812）。本文介绍了SDSS-IV调查公开数据的位置和格式。我们提供了重要技术论文的参考资料，这些论文描述了如何获取这些数据（包括目标和观测细节）并进行科学处理。SDSS网站（www.sdss.org）已针对此版本进行了更新，并提供数据下载链接以及数据使用教程和示例。SDSS-IV计划继续收集天文数据，直到2020年，SDSS-V将紧随其后。
SDSS-IV MaNGA: New benchmark for the connection between stellar angular momentum and environment: a study of about 900 groups/clusters
根据特定恒星角动量的代用指标$λ_{R_e}$，可以将低红移早型星系分为慢转星系和快转星系。对少数邻近星系团的详细研究表明，慢旋转星系通常出现在星系团的中心，那里的数量密度最高，而快旋转星系则遵循早期星系的趋势，即数量随着局部密度的增加而增加。利用Sloan Digital Sky Survey的Mapping Nearby Galvanian at Apache Point Observatory巡天的3900个星系的恒星运动学资料，研究了慢速和快速自转星系的环境分布。对于星系群接近$z=0.08$，没有观察到与MANGA，但满足必要条件的慢旋转，我们直观地分配慢/快旋转分类，以获得一个完整的样本。我们的最终目录包含大约900组五个或更多的成员。我们观察到的运动学形态密度（kT- $Σ$）的关系，为每个组，并发现一个大规模的慢旋转的分数随着数量密度的增加。我们提供的证据表明，所观察到的角动量与环境在固定的恒星质量的趋势的缺乏，部分是因为集群之间的最大密度不同，以及大规模的慢旋转的位置与星系群和集群的峰值密度密切相关。我们的结论是（预计）数密度相对于集群的峰值是更根本的比绝对数密度的影响丰度的慢旋转。我们发现，kT- $Σ$关系确实存在于固定的恒星质量，我们排除了假设的kT- $Σ$关系是一个结果的动力学摩擦单独，而不是认为，大质量的慢旋转与他们的主机集群的层次增长。

SDSS-IV MaNGA: A Catalogue of Spectroscopically Detected Strong Galaxy-Galaxy Lens Candidates
我们在光谱上探测到了8条可能的候选发射线，17条可能的候选发射线，以及69条可能的强星系-星系引力透镜候选发射线，这些候选发射线是在Apache Point Observatory（MaNGA）完成的邻近星系测绘中包含的约10，000个星系目标的光谱中发现的。这种搜索是基于透镜物体（SILO）项目的光谱识别方法，该项目扩展了BOSS发射线透镜调查（BELLS）和斯隆透镜ACS调查（SLACS）的光谱检测方法。我们扫描了我们从前景减去行堆叠光谱（RSS）的堆栈中构建的共同添加的残差，因此可以使用sigma-clipping方法来拒绝宇宙射线和其他形式的瞬变，这些瞬变仅影响组合曝光的一小部分。我们还构建了窄带图像的信噪比的共同添加的残差观察透镜源图像的迹象。我们还使用了几种方法来计算可能的强透镜制度，每个候选透镜，以确定候选背景星系可能居住在足够靠近星系中心的强透镜发生。我们提出的光谱红移的增值目录（VAC）的数据发布17（DR 17）的SDSS-IV。我们还介绍了镜头候选人，光谱数据，并在VAC的DR 17窄带图像。这些透镜候选者的高分辨率后续成像预计将产生确认的A级透镜的样本，具有足够的角尺寸，以探测来自最佳拟合透镜模型的质量与来自观测到的恒星速度的动态质量之间可能存在的差异。
