论文摘要
我们在EBOSS调查（Lesser）项目中介绍了镜头LAES，该项目旨在在扩展的Baryon振荡光谱调查（EBOSS）中寻找镜头的Lyman- $α$发射器（LAES）。最终目录包含361个候选镜头系统。镜头星系是红置$ 0.4 <z <0.8 $的发光红色星系（LRGS），源星系是Redshift $ 2 <z <3 $的Laes。 EBOSS的光谱分辨率（$ \ sim $ 2000）使我们能够进一步确定Lyman-$α$（$ \ rmlyα$）排放的精细结构。在我们镜头的LAE候选人中，有281个系统呈现单峰线轮廓，而80个系统显示了双峰功能。目录的未来光谱/成像随访观察结果可能会阐明各种$ \ rmlyα$线形态的起源，并提供了有前途的实验室来研究低质量暗物质光环/subhaloes。
We introduce the LEnSed laeS in the Eboss suRvey (LESSER) project, which aims to search for lensed Lyman-$α$ Emitters (LAEs) in the Extended Baryon Oscillation Spectroscopic Survey (eBOSS). The final catalog contains 361 candidate lensing systems. The lens galaxies are luminous red galaxies (LRGs) at redshift $0.4 < z < 0.8$, and the source galaxies are LAEs at redshift $2 < z < 3$. The spectral resolution of eBOSS ($\sim$2000) allows us to further identify the fine structures of Lyman-$α$ ($\rm Lyα$) emissions. Among our lensed LAE candidates, 281 systems present single-peaked line profiles while 80 systems show double-peaked features. Future spectroscopic/imaging follow-up observations of the catalog may shed light on the origin of diverse $\rm Lyα$ line morphology, and provide promising labs for studying low mass dark matter haloes/subhaloes.
