Example spectra of high-priority ‘Rubies’. False colour images are constructed from the NIRCam F150W, F277W, and F444W filters, and they show the location of the NIRSpec microshutters. The low-resolution PRISM spectra (with global background subtraction; see Sect. 3) reveal a great diversity in spectral shapes, both in terms of continuum features (Balmer breaks and jumps) and the presence of different emission lines. The medium-resolution G395M data deblend lines that are difficult to interpret from the PRISM spectroscopy alone, and provide strong constraints on the ionised gas kinematics. We broadly identify four types of SEDs (from top to bottom): galaxies with strongly dust-obscured star formation, massive quiescent galaxies, extremely red AGNs, and extreme emission line galaxies. We note that medium-resolution NIRSpec data of RUBIES-EGS-8488 was also presented by Larson et al. (2023) with ID CEERS_1019.
