Maps for A2744-YD4 from JWST NIRSpec IFU. All the maps are obtained from the (wavelength-dependent) spatially smoothed data cube (details in Sect. 2.2). No extinction correction is applied. A cut of S/N > 3 on the peak flux of each line is applied. Median stellar continuum emission in the observed spectral range 2–3 μm (0.23–0.34 μm rest-frame; left); [O III] integrated flux (centre); map of oxygen abundance, 12+log(O/H) (right). Contours mark the continuum from first panel. NIRSpec PRISM/CLEAR spectrum extracted from a circular aperture with radius of 0.15″ centred at the location of the target YD4 (bottom).
