ADC_Keywords: Active gal. nuclei ; Ultraviolet ; Redshifts ; Equivalent widths Keywords: galaxies: evolution - galaxies: ISM - galaxies: luminosity function, mass function - galaxies: starburst - ultraviolet: galaxies Abstract: We have used the GALEX (Galaxy Evolution Explorer) spectroscopic survey mode, with a resolution of ∼8Å in the far-ultraviolet (FUV; 1350-1750Å) and ∼20Å in the near-ultraviolet (NUV; 1950-2750Å) for a systematic search of Lyα-emitting galaxies at low redshift. Our aim is to fill a gap between high-redshift surveys and a small set of objects studied in detail in the nearby universe. A blind search of 7018 spectra extracted in five deep exposures (5.65deg2) has resulted in 96 Lyα-emitting galaxy candidates in the FUV domain after accounting for broad-line AGNs. File Summary:
