Contribution of AGN emission to the PRIMAger bandpass. Thin grey lines show a z = 2 galaxy SED including different AGN properties (see Table 2), divided by the SED without an AGN component. As an example, the emission of one AGN model with different f_AGN contributions (15, 30, and 45% of the total IR luminosity) is shown in red thick lines. The fluxes obtained for integration in the equivalent filters with centre wavelengths listed in Table 1 for PHI+PPI1+PPI2 are shown as red circles. The inset panel shows the SEDs corresponding to the red lines (for f_AGN = 0% and f_AGN = 45%) over the full UV to submm wavelength range. The PRIMAger bands are well suited to probing the impact of AGN emission on the IR SED of galaxies.
