论文摘要
Hobby-eberly望远镜暗能量实验（HETDEX）是一项大规模的光谱调查，而无需预先选择源，在1.9 <z <3.5中搜索〜540 ver^2的〜540 ver^2。利用如此广泛的调查，我们使用早期的HETDEX数据进行了一项试点研究，以搜索镜头的Lyman-Alpha发射器。在使用HetDex覆盖的先前已知的镜头LAE进行概念验证后，我们在HetDEX光谱样品中搜索以前未知的镜头LAE。我们提出了一个由前景，红色，非星形星系在z〜0.4-0.7处的26个电势LAE的目录。我们估计每个候选系统的放大倍数，发现12个候选者在强烈的镜头范围内（放大$ $ $> 2）。这些潜在镜头LAE的后续观察有可能确认其镜头的性质，并更详细地探索这些遥远的星系。
The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is a large-volume spectroscopic survey without pre-selection of sources, searching ~ 540 deg^2 for Lyman-alpha emitting galaxies (LAEs) at 1.9 < z < 3.5. Taking advantage of such a wide-volume survey, we perform a pilot study using early HETDEX data to search for lensed Lyman-alpha emitters. After performing a proof-of-concept using a previously known lensed LAE covered by HETDEX, we perform a search for previously unknown lensed LAEs in the HETDEX spectroscopic sample. We present a catalog of 26 potential LAEs lensed by foreground, red, non-star-forming galaxies at z ~ 0.4 - 0.7. We estimate the magnification for each candidate system, finding 12 candidates to be within the strong lensing regime (magnification $μ$ > 2). Follow-up observations of these potential lensed LAEs have the potential to confirm their lensed nature and explore these distant galaxies in more detail.
