SDSS Lenses

The Sloan Digital Sky Survey (SDSS) Luminous Red Galaxy (LRG) spectrum below is lensing a background Emission Line Galaxy (ELG). The ELG in this spectrum can be identified by the [OII] 3727 and 3729 A emission lines, the H beta 4865 A emission line, and the H alpha 6564 A emission line.

I have used the Sky Residual Correction technique detailed here, http://sites.bu.edu/murdock-hart/sky-subtraction/sky-residual-correction/, to assist in the search for gravitationally lensed ELG in the SDSS data set. The table below lists the lensed ELGs which were found in the SDSS LRGs after sky residual correction.
