Abstract

We study the production and escape of ionizing photons of a sample of 588 H$\alpha$ (Ha) emitters (HAEs) at z=2.2 in COSMOS by exploring their rest-frame Lyman Continuum (LyC) with GALEX/NUV data. We find 8 candidate LyC leakers with f$_{esc}$>60% out of a clean subsample of 191 HAEs (i.e. without any neighbour or foreground galaxy inside the GALEX PSF). Overall, we measure a very low escape fraction f$_{esc}$ z
