Lyman-continuum (LyC) radiation from galaxies appears to constitute an increasingly significant component of the ionizing background at redshifts beyond z 3, and almost certainly dominates the radiation field at the epoch of H I reionization. Therefore, estimating the contribution to the ionizing background from galaxies represents a fundamental goal for observational cosmology. We have acquired deep LRIS narrowband imaging of the Q1549+1933 field with a filter tuned to the wavelength range just below the Lyman limit (3420 A) of a redshift spike of galaxies at z=2.85. The field contains 49 Lyman Break Galaxies (LBGs) at z ≥ 2.85, and 199 narrow-band selected Lyman Alpha Emitters (LAEs) (73 spectroscopically confirmed at z 2.85). We present the photometry of 24 objects (19 LAEs, 5 LBGs) with robust narrowband detections and a multiwavelength analysis of the intensity and spatial distribution of the escaping ionizing radiation.
