Spatial correlation between X-ray and IR data from the remnant’s location. Left panel: RGB image, displaying combined eRASS:4 X-ray data in the 0.3–1.1 keV energy band (red), IRAS 25 µm data (green), and IRAS 100 µm data (blue) from the location of the remnant. Right panel: Combined IRAS 25 µm data (green) and IRAS 100 µm data (blue) from the location of the remnant. The red contours represent two levels of eRASS:4 X-ray data in the 0.3–1.1 keV energy band which we overlaid to IRAS data sets, aiming at inspecting the IR emission at the location of the X-ray excess, as observed with eROSITA, and enhancing the apparent anti-correlation in the two distinct energy bands, that is to say how the IR emission “respects” the X-ray excess emanating from the remnant in the south and west.
