dc.descriptionThe Wide Field Imager Lyman-Alpha Search (WFILAS) is a search for Lya emitting galaxies at z~5.7. Deep images from the Wide Field Imager (WFI) on the ESO/MPI 2.2m telescope have been used to detect 7 bright Lya emitting candidates in three fields covering 0.74 sq. degree on the sky. For this we used three narrowband (FWHM ~70A), one encompassing intermediate band (FWHM \~220A) and broadband B and R filters. One has thus far been spectroscopically confirmed as a Lya emitting galaxy at z=5.721 using FORS2 at the VLT. This galaxy shows a bright, well resolved asymmetric line profile, which is characteristic of Lya emitting galaxies. In one of our three fields, the Chandra Deep Field South (CDFS), we find an overdensity of Lya emitters in agreement with other surveys that have targeted this region. A statistically complete sample of our candidates probes the bright-end of the luminosity function, confirming earlier results from other smaller, deeper surveys.
