TL;DR: In this paper, the spectral energy distributions of selected ELAIS sources in N1 detected by SWIRE, most with spectroscopic redshifts, are modelled in terms of a simple set of galaxy and quasar templates in the optical and near infrared, and with a set of dust emission templates (cirrus, M82 starburst, Arp 220 starburst and AGN dust torus) in the mid infrared.

TL;DR: In this article, the authors study the ultraviolet to far-infrared (hereafter UV-to-IR) SEDs of a sample of intermediate-redshift (0.2 ≤ z ≤ 0.7) galaxies from the ELAIS N1 and ELAis N2 fields by fitting a multi-wavelength data set to a library of GRASIL templates.
