| About this Image |
|---|
The irregular galactic supernova remnant 3C391 (also known as G31.9+0.0) is depicted in this XMM-Newton X-ray false colour image. The south east-north west elongated morphology of this SNR could be due to its interaction with surrounding molecular clouds. Its clumpy structure is due to the spatial distribution of the X-ray thermal emission: hotter and brighter through the interior (where several knots are seen), but colder and fainter towards the edges with a smoother faint medium (green) X-ray emission of the gas in the south west direction. Several point-like soft X-ray emitting sources are detected in the surroundings. The RGB image is colour coded as: red=0.3-1 keV, green=1-2 keV, blue=2-10.0keV.

| Detailed Caption | The data were taken on 2003-04-18. The single band images were first created using an "home made" script and then smoothed with an Adaptive method (width=5.0) applying the "asmooth" SAS task; the RGB colour image was obtained combining the layers by the GIMP image processing software, while the single band coloured images were prepared with the DS9 image processing software. | ||
