SOAR Hα imaging in comparison to the X-ray properties of RXC J2014.8−2430. Left: SOAR net Hα image. The regions used for spectral extractions reported in Table 2 are shown here. The white box labelled ‘H-α centre’ corresponds to the region used for spectroscopy. We note that the bright source to the north-east of the Hα peak is a foreground star. Middle: Chandra X-ray surface brightness from Fig. 1 (left) with SOAR contours from the left panel. Right: temperature map from Fig. 1 (right). The peak in the Hα emission is offset from the peak in the X-ray surface brightness. However, the south-western spur in the Hα emission appears to trace the coolest, brightest gas seen in X-ray. The images are 22″ wide, corresponding to 59.3 kpc.
