Lyman-{alpha} emitters lensed by galaxies

We introduce the LEnSed laeS in the Eboss suRvey (LESSER) project, which aims to search for lensed Lyman-{alpha} emitters (LAEs) in the Extended Baryon Oscillation Spectroscopic Survey (eBOSS). The final catalogue 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 (~2000) allows us to further identify the fine structures of Lyman-{alpha} (Ly{alpha}) 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 catalogue may shed light on the origin of diverse Ly{alpha} line morphology, and provide promising labs for studying low-mass dark matter haloes/subhaloes.
