Integrated [O III]λ5007 Å flux map of HZ4 from the JWST NIRSpec/IFS R2700 cube. We show the 5, 25, and 75σ of [O III] as green contours. Red contours illustrate the [C II] emission from the ALMA Briggs-weighted (robust = 0.5) cube, at 5, 15, and 25σ, respectively. HST/WFC3 F160W image is reported in black contours. The pink, white, and green ellipses represent the ALMA beam size, the HST F160W point spread function (PSF), and NIRSpec IFS PSF at 3.2 μm estimated by D’Eugenio et al. (2024), respectively.
