TITLE: Optical/UV spectral features of AGN and galaxies: challenges for the high-z Universe
 
 
ABSTRACT:  The recent observational progress has enabled detailed analyses of the rest-frame UV and optical spectra of galaxies both at low and high redshifts. Future facilities, such as JWST, will push these previous studies up to the epoch of reionization. Over the last years, significant effort has focussed on developing theoretical models tailored to the interpretation of high-z galaxy spectra. I will first review the current status of modelling the emission from different ionizing sources, such as hot stars, AGN and radiative shocks. I will then show how model predictions, combined with innovative observations (e.g. from MUSE/VLT) and spectral analysis tools, can help us gain new insights into the nature of the ionizing radiation and the physical conditions of the interstellar medium of high-z galaxies and low-z analogous of primeval galaxies.
