Photometric SED fitting strongly supports a high-redshift solution for EGSY8p7: red points show magnitudes, where the horizontal error marks the filter width, and triangles denote 1σ upper-limits from non-detections. The blue SED shows the best-fit template at z = 8.57. The magenta SED shows the z = 8.48 solution adopting the strong emission line template used in RB15 (see their work for more details on the templates). The gray SED shows the best-fit low-redshift template, which cannot explain the absence of detection in the optical bands and which is ∼10⁷ times less likely than the high-redshift solutions.
