Left panel: XMM-Newton color image of the X-ray emission in the 0.3–10 keV energy range (in blue) of G304.6 + 0.1 with the radio contours (in white) at 843 MHz overlaid. The extraction regions used for the spectral analysis are also indicated as yellow circles. Central panel: IRAC three-channels composed image of G304.6 + 0.1 with the radio contours (in white) at 843 MHz overlaid. Right panel: composite color image of the radio, mid-infrared, and X-ray emissions of G304.6 + 0.1. All images are in equatorial coordinates J2000.
