Mosaic image of all XMM-Newton observations used in the updated SMC survey. Red/green/blue: 0.2–1.0/1.0–2.0/2.0–4.5 keV intensities. White circles denote the sources selected from Secrest et al. (2015), green circles those from the HMQ and MILLIQUAS survey (Flesch 2015, 2017), and red circles mark the 81 new AGN candidates that we identified. The magenta crosses indicate the candidates for obscured AGN. The circle radius is scaled with the uncertainty on the X-ray positions.
