Left panel: Chandra image, covering a 16×16 arcmin² field of view, of G272.2−3.2 in the three X-ray energy bands: soft (0.5−1.0 keV) in red, medium (1.0−1.8 keV) in green, and hard (1.8−3.0 keV) in blue. The image corresponds to the merged Chandra observations. Right panel: combined XMM-Newton MOS1 and MOS2 image in the hard X-ray energy range (1.8−3.0 keV). The boundary of the SNR is indicated in yellow. The circle in the central part of the SNR indicates the reverse shock interface. The region of the elongated hard emission is also indicated by a yellow ellipse. R_CD and R_S indicate the radii of the contact discontinuity and the forward shock front, respectively. Horizontal and vertical axes are labeled using J2000.0 right ascension and declination.
