Summary

Active Galactic Nuclei (AGN) are thought to play major role in the evolution of galaxies, impacting both star formation and gas accretion onto galaxies.Clearly there is a need to determine the star-formation rates(SFRs) in AGN host galaxies in order to understand and disentangle the growth of SMBH and their hosts. At the same time, contribution of their non-stellar emission in the measured emission from a galaxy impacts all SFR tracers. In this chapter we present the different types of AGN and the main mechanisms responsible for their emission in different wavebands. We discuss the methods used to identify whether a galaxy hosts an AGN and the available techniques to determine the fractional contribution of the AGN to various SFR tracers.
