From left to right, image cutouts of XID5395 at increasing wavelengths and resolution: a) SUBARU Suprimecam I-band (FWHM ~ 1″); b) UltraVISTA H-band (FWHM ~ 0.7″); c) SUBARU IRCS H-band (FWHM ~ 0.2″); d) SUBARU IRCS K-band (FWHM ~ 01″); e) same as panel d) with the X-ray contours superimposed (from Chandra Legacy data; Civano et al. 2016). The cutouts have a size of ~ 4′′ across (e.g. comparable to the SINFONI FoV). The 1′′ scale is given for reference in panel c). In the same panel we also indicate different components discussed in the text, as labelled. North is up and east is left. Chandra contours are not corrected for astrometry.
