We present the status and results of a search for Lyman continuum emission from galaxies at z 1. We use GALEX data in the Extended Groth Strip. Our method is to stack FUV image flux at locations of DEEP2 redshift catalog galaxies in the redshift range 1 < z < 1.5. In this range, the GALEX FUV band (1350-1800 A) is sensitive only to rest wavelengths below 912 A. We normalize FUV flux to NUV flux and calculate the Lyman continuum emission escape fraction by fitting SED models to broad-band fluxes from ground-based surveys of the same galaxies.
GALEX is a NASA Small Explorer mission with contributions from France and South Korea.
This work uses data from the AEGIS collaboration, which is supported by grants from the National Science Foundation, NASA, and the Keck Observatory.
