The emission of galaxies over the whole electromagnetic spectrum

Abstract

The Spectral Energy Distributions (SEDs) of galaxies contain a wealth of information on the physical processes at play in galaxies and on their components: gas, stars, dust, Active Galactic Nuclei (AGN). Many of the fundamental properties which shape stellar population ensembles are encoded in their SEDs. In this paper, we will try to keep track of the main properties, e.g. star formation history, total mass in stars, characteristics of the AGN, but also the physical state and amount of gas and dust. We will also see how to use modern tools to collect information on the source of the emission in a way consistent with the observed data from the observed far-ultraviolet to far-infrared ranges.
