Three colour XMM-Newton image of the NGC 253 disc and nuclear region

January 24, 2013
Emission detected in all three EPIC instruments (MOS1, MOS2 and PN) have been merged together. Red, green and blue show respectively (0.2-0.5) keV, (0.5-0.9) keV and (0.9-2.0) keV bands, while the hard (2-10) keV emission is shown superimposed as contours. Shown in detail to the lower left is a factor 2 zoom-in on the nuclear region. The ellipse indicates the optical extent of NGC 253. (Picture courtesy Wolfgang Pietsch).
