NUV image from Fig. 8 bottom-right, with stellar clusters from Johnson et al. (2016) shown by the red dots. The clusters have mass greater than 10³ M_⊙ and ages less than 100 Myr. The 0.4–1.25 keV X-ray contours from Fig. 2 are also shown in blue to highlight the correlation between the stellar clusters and X-ray emission. No clusters are plotted in the 10 kpc ring north of the core as this region was not studied in Johnson et al. (2016).
