Figure 5: The Seyfert 2 galaxy NGC 7582 (from Bianchi et al. [95]). (a) HST NIR to optical ratio, mapping the amount of dust in the circumnuclear region of NGC 7582. The white contour plots refer to the Chandra emission below 0.8 keV, while the red ones the ratio shown in the right panel. (b) Chandra 0.8–1.3 to 0.3–0.8 keV ratio. The red contour plots shown in left panel refer to this image, but the scale is different, as outlined by the broken-line rectangle. In both panels, the black cross indicates the position of the nucleus.
