MUSE continuum image and spectra of foreground galaxy in the field of 4C+03.24. Upper left: Continuum image extracted from MUSE cube around 7250 Å. The blue dot marks the position of the potential foreground continuum source. The blue circle shows the r = 0.25″ aperture from which the spectrum was extracted. The red box indicates the NIRSpec IFU FoV. The green contours are same radio map as in Fig. 7. The dashed red contours are the same NIRSpec IFU optical continuum as in Fig. 7. Lower panel: Full MUSE spectrum extracted at the foreground galaxy position with a focus on the continuum. The red dotted vertical line indicates Lyα from 4C+03.24. The vertical gray dashed lines mark the zoom-in region around the emission line of the foreground galaxy. Upper right: Zoom-in view of the potential foreground [O II]3726, 3729 line.
