Stacked spectra using the NIRSpec/MSA prism spectra of galaxies at 4 ≤ z < 10 belonging to the JADES survey. Left panel: spectrum extracted from two pixel off central downwards (i.e. ∼1.2 kpc radius) of the 2D stacked spectrum. The cyan (violet) line is the best-fit function for the continuum and [O III]λ5007, Hβ ([O II]λ3727, [Ne III]λ3869) spectral lines. Central panel: spectrum extracted from one pixel off central downwards of the 2D stacked spectrum. Colour coding and labels are the same as left panel. Right panel: spectrum extracted from one pixel off central upwards of the 2D stacked spectrum. Colour coding and labels are the same as left panel.
