Descripción
We present a new determination of the evolving spectral energy distribution of the Extragalactic Background Light (EBL) purely based on galaxy data. Our calculations use multiwavelength observations from the ultraviolet to the far-infrared (far-IR) of a sample of aproximately 150,000 galaxies detected up to z~6 from the five fields of the Cosmic Assembly Near-Infrarred Deep Extragalactic Legacy Survey (CANDELS). These unprecedented data allow us to reduce existing uncertainties in the far-IR contribution and to improve the evolution with redshift relative to current EBL models. From our estimates, we can also derive other fundamental cosmological properties of the Universe such as the cosmic star formation history and the evolution of the galaxy luminosity densities.
