Fig. 12.
Observed SEDs of the AGN candidates and comparison with various SED templates. Top: SEDs of the AGN candidates normalised at 3.5 μm. The bright AGN candidates are marked with magenta circles. Bottom: similarly normalised SWIRE SED templates of AGN (Mrk 231; magenta) and galaxies of E (13 Gyr old), Sc, M 82, and NGC 6090 (black) redshifted to z = 0.3. The normalisation wavelength is indicated by a black solid vertical line in each panel.
