Ionised gas properties of GAMA 526784. First panel: dust attenuation (AV) map derived from the Balmer decrement. Second panel: [SII] λ6716/λ6731 ratio, which serves as a proxy for electron density. Third panel: gas-phase metallicity (12+log (O/H)) map estimated using the O3N2 diagnostic (Marino et al. 2013). Fourth panel: SFR per spaxel derived from the Hα luminosity. The inset panels show the gradients along the two rectangles in the maps, with grey bands representing measurement uncertainties. These maps reveal localised dust attenuation, an overall low [SII] ratio which may be indicative of high electron densities, low chemical enrichment in the ionised gas, and localised star formation concentrated in regions with young star clusters.
