Composite view of PKS 1138-262 (z = 2.43). The main frame is at 1.6 μm HST image while the inset corresponds to the I band. The magenta contours show the 8.4 GHz data overlaid at 3, 5, 10, 20, 30, 50, 75, 100, 125, 150, and 200σ, with an rms = 30 μJy. Note that most of the sources around the radio galaxy are at the same redshift (Hatch et al. 2011).
