Extended Data Fig. 5: The spectra of the extended Mg II emission.
From: Bipolar outflows out to 10 kpc for massive galaxies at redshift z ≈ 1
The spectra in each panel are extracted from the grid cell at the corresponding position in Fig. 1. The black and red spectra denote the edge-on and face-on galaxy samples, respectively. In each panel, the coloured shading represents the 1σ error range of the corresponding spectra. The panels for which the peak of the Mg II 2,796 Å line in the black spectra falls below the 2σ threshold are marked with a lighter colour.
