Upper-left: a) 2–7 keV Chandra image of IRAS F00183–7111. The X-ray source is point-like and coincides with the nuclear position of the ULIRG; upper-right: b) 0.4–1 keV Chandra image of the same area. The blue cross indicates the position of the 2–7 keV source. The magenta contours for a smoothed version of the same image are overlaid. The image is elongated towards the eastern direction; lower panel: c) [Oiii]λ5007 contours (black) are overlaid on the 5007 Å continuum in greyscale. The images were taken by VLT/VIMOS (Spoon et al., in prep.). The displacement between the [Oiii] and the continuum is considered to be due to obscuration in the nucleus, as discussed in Spoon et al. (2009). The soft X-ray contours are also overlaid in red, and the 2–7 keV image centroid is marked in blue. An eastern [Oiii] knot is seen at 8 arsec from the nucleus.
