Fit of the z ~ 8 galaxy candidate SED at high- (black line) and low-redshift (magenta line). ACS upper limits are shown at 1σ and the IRAC non-detection is plotted at 3σ. The high-z SED fit shown here is for 1/50 solar metallicity, imposing an age prior of >50 Myr. The high-redshift solution shows an excess at 4.5 μm due to [OIII] and Hβ emission lines, as already observed in the z ~ 7.51 galaxy published in F13. P(z) and χ2(z) are also plotted.
