Nature and chemical abundances of a sample of Lyman-α emitter objects at high redshift

Abstract

We built a grid of photoionization models and compiled already available observational emission line intensities (1000 53. Values for C/O abundance ratio derived for the LAEs seem to be consistent with those derived for local star forming objects with similar metallicities, while an overabundance of N/O was found for most of the LAEs.Instituto de Astrofísica de La Plat
