From: The supernova remnant SN 1006 as a Galactic particle accelerator
a Chandra flux images (photons cm−2 s−1) in the 0.5–1 keV (green) and 2.5–7 keV (blue) bands, and column density (in 1020 cm−2) of HI in the [+5.8, +10.7] km s−1 range30 (red). Lines mark angles (θ) relative to the ambient magnetic field, B. The white segment indicates an angular distance of \(5^{\prime}\). b radio continuum map62 (Jy beam−1) at 1.4 GHz (red), with Balmer Hα emission31 (10−17 erg s−1 cm−2, in light blue). c, d 0.5–1 keV and 2.5–7 keV maps, respectively, with the 9 regions selected for spectral analysis superposed in blue. e close-up view of the Hα map. The dashed circle marks the position of the forward shock. Minimum and maximum values for each panel are indicated in the corresponding color bar. All scales are linear, except for the light blue in b, which is in square root scale.
