Top: observed and model SEDs of the Cosmic Eye. The global SED is obtained with a Seyfert galaxy template from P07 but is a very poor fit, although it is the best fit among our libraries (an SMG template from M10 manages a better fit of the visible-NIR photometry, but misses the FIR data by more than one order of magnitude). The FIR data are best fitted by a R09 template, that accurately matches the photometry and 1σ limits, only slightly over-estimating the 1.2 mm detection. Bottom: comparison of the Eye’s best Calzetti fits with and without emission lines to the stellar SED. Also plotted is the very old (~1.5 Gyr) SMC-based model, which despite its large age, has favored a constant SFR and produces stronger lines than the Calzetti-based model. The difference between the three is almost imperceptible.
