论文摘要
我们可以在光谱镜上检测到838个可能的可能性，有448个可能的可能性和265个可能的强晶状体候选物，其中包括Sloan Digital Sky Survey（SDSS）的第十六个数据发布（DR16）的扩展Baryon振荡光谱调查（EBOSS）中包含的大约200万美元的Galaxy Spectra（EBOSS）。我们应用了Baryon振荡光谱调查（BOSS）发射线透镜调查（Bells）的光谱检测方法，并添加高斯拟合信息，评分，其他检查可观察物以及其他检查方法，以改善我们的选择方法。我们观察到来自SDSS-I/II的传统调查和DESI Legacy调查的低分辨率图像中的477名候选人，其镜头证据高于$ 12 \％$的$ 12 \％$，比观察到的贝尔斯候选者百分比具有相似的镜头证据。我们在最新和改进的老板调查中的搜索量增加了20美元\％$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $增加，预计搜索所有Boss和Eboss Galaxies的镜头候选人数量增加了。我们候选人的目标和背景红移的分布与候选人相似，并确认了铃铛观测中的镜头。我们介绍了SDSS DR16中增值目录（VAC）中透镜对象（Silo）候选物的光谱鉴定。在后续高分辨率成像中对这些镜头候选物的检查可能是SDS中先前光谱检测调查中发现的镜头的两倍以上，这将扩展SDSS中先前的晶状体调查的结果到更高的红色转移，约束螺旋星系中的质量结构模型的约束，并在包括可能的较低的图像中测试了可能的较低的图像。
We spectroscopically detected 838 likely, 448 probable, and 265 possible strong lens candidates within $\approx2$ million galaxy spectra contained within the extended Baryon Oscillation Spectroscopic Survey (eBOSS) from the sixteenth data release (DR16) of the Sloan Digital Sky Survey (SDSS). We apply the spectroscopic detection method of the Baryon Oscillation Spectroscopic Survey (BOSS) Emission-Line Lens Survey (BELLS) and add Gaussian fit information, grading, additional inspection observables, and additional inspection methods to improve our selection method. We observed 477 candidates with lensing evidence within low-resolution images from both the Legacy survey of SDSS-I/II and the DESI Legacy survey, which is $12\%$ higher than the percentage of BELLS candidates observed with similar lensing evidence. Our search within the latest and improved reductions of the BOSS survey yielded a $20\%$ increase in the number of lens candidates expected from searching all BOSS and eBOSS galaxies. The distribution of target and background redshifts of our candidates is similar to the candidates and confirmed lenses within the BELLS observations. We present our Spectroscopic Identification of Lensing Objects (SILO) candidates in a value-added catalogue (VAC) in SDSS DR16. The examination of these lens candidates in follow-up high-resolution imaging may yield more than twice the lenses found in previous spectroscopic detection surveys within SDSS, which would extend the results of previous lens surveys within SDSS to higher redshifts, constrain models of mass structures in spiral galaxies, and test if including the identification of possible lensing features within low-resolution images has merit to spectroscopic detection programs.
