Morphological model of NIRCam rest-frame UV of A2744-45924 (PSF FWHM ≈0.03″). The left panels display the F070W and F090W stamps, corresponding to central rest-frame wavelengths of approximately 1290 Å and 1651 Å, respectively. The center panels show the best-fit models obtained with IMFIT, while the right panels present the residuals. The F070W image, probing the bluest part of the rest-frame UV spectrum of A2744-45924, including Lyα, reveals a prominent extended component. In contrast, this component is less clear in F090W. An alternative view of the models can be found in Fig. A.1.
