Near-UV starlight around radio galaxy B2 0902+34. Left: HST/WFC3_F105W image of the rest-frame near-UV starlight. The radio source is shown with the same red contours as in Figure 1. Right: zoom-in on the stellar nebula, with a 5 pixel boxcar smoothing applied. The dashed yellow ellipse highlights the region with substantially lower stellar flux, likely due to high obscuration, seen at the location of the southern 26 GHz radio component. The orange contours show the stellar emission starting at 28% and increasing by 9% of the peak intensity of the nebula.
