Abstract: Averaged spectral energy distributions (SEDs) of active and starburst galaxies, from the 12 μm sample in the local universe, and QSOs, from an optically selected sample at a mean redshift ⟨ z ⟩ = 0.7, are built from optical, near-IR, and far-IR (FIR; IRAS and Infrared Space Observatory ) photometric observations. These SEDs are then used to predict at various redshifts the number of Seyfert type 1 and type 2, starburst, and normal galaxies and QSOs that will be detected by future space missions dedicated to FIR and submillimeter astronomy, such as SIRTF and Herschel . These predictions are then compared with the expected capabilities and detection limits of future deep FIR surveys. Possible ways to identify active galactic nucleus candidates on FIR color-color plots for follow-up observations are then explored.
