Smoothed 0.4–6 keV intensity images of M104 in panel (a) in the 23′ × 23′ region. Detected X-ray sources are marked with circles of the 90% EER. GC sources are further marked with crosses. The ellipse (8 7 × 3 5) represents the D ₂₅ isophote of the galaxy; the large circle encloses sources of interest; (b) the 10′ × 10′ region. The two dashed ellipses outline the dust lane and (c) the central 1 5 × 1 5 region.
