Spectra, photometry, and SED modeling of RUBIES-UDS-QG-z7 at z = 7.2758±0.0011. Top: Photometry (blue squares), the JWST/NIRSpec PRISM spectrum (black line), and its uncertainty (gray line) that we jointly modeled with BAGPIPES (red line) in the observed frame. The normalized residuals of the modeling are shown in the lower inset. Center: Rest-frame UV spectrum covered by the extended G235M grating. Bottom: Rest-frame optical spectrum covered by the G395M grating. We mark in red the expected location of emission and absorption lines at the derived systemic redshift, z_spec = 7.2758, as labeled. The flux densities in the bottom panels have been rescaled by (1+z) to conserve the energy.
