Abstract:
We aim to study the spatial distribution of the physical and chemical
properties of the X-ray emitting plasma of the supernova remnant
G272.2-3.2, in order to obtain important constraints on its
ionization stage, the progenitor supernova explosion, and the age of
the remnant.
We report on combined XMM-Newton and Chandra images, median photon
energy maps, silicon and sulfur equivalent width maps, and a spatially
resolved spectral analysis for a set of regions of the remnant.

Note (1): Additional informations on images as follows:
1 = (g272_1.fits) Chandra image, covering a 16x16 arcmin2 field of view,
of G272.2-3.2 in the three X-ray energy bands: soft (0.5-1.0keV) in red,
medium (1.0-1.8keV) in green, and hard (1.8-3.0keV) in blue.
The image corresponds to the merged Chandra observations.
2 = (g272_2.fits) Combined XMM-Newton MOS1 and MOS2 image in the hard
X-ray energy range (1.8-3.0keV). 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. RCD and RS 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.
