Warm and cold dust luminosity ratio maps for (left) the northeast and (right) the southwest region in the halo of Cen A. The green contours show the GALEX/FUV intensity distribution, where the contours correspond to the levels of 0.00155, 0.002, 0.0035, and 0.006 ct s⁻¹ per 1.5 arcsec² and 0.0015, 0.00155, 0.0017, and 0.00185 ct s⁻¹ per 1.5 arcsec² for the northeast and the southwest region, respectively. The yellow contours show the Herschel 250 μm intensity distribution, where the contours correspond to the levels of 9, 10.5, 12, and 18 MJy sr⁻¹.
