Construction of spectral libraries of star-forming galaxies at 0.3 <= z <= 2.5
First author: Louis Gabarra
Spectral energy distribution (SED) models of galaxies at 0.3 <= z <= 2.5 were constructed to be processed by the Euclid spectroscopic channel simulator in order to investigate the Euclid Near- Infrared Spectrometer and Photometer (NISP) capabilities. We developed a solid methodology to build a realistic and representative synthetic SED library of star-forming galaxies, including reliable emission line fluxes and widths. The construction of the SEDs consists in computing the continuum using the Bruzual & Charlot (2003) models, calling out SED fitting parameters available in publicly released multi-wavelength catalogues. Emission lines were added using empirical and theoretical relations.
