MRS [O III] 5008 Å (left) and Hα (right) emission line maps. The [O III] 5008 Å and Hα line maps are generated by integrating a narrow velocity range, −150 < v [km s⁻¹] < 150, around the peak of each emission line. The dashed cyan circles show the aperture chosen to extract the 1D spectra. The gray area represents the MRS spatial resolution (PSF FWHM) at the observed wavelength of each emission line. These line maps demonstrate that GN-z11 is spatially unresolved in the MRS observations.
