Two-color image of Tycho to demonstrate the spatial coincidence of the 4–6 keV Chandra data (in red) and the 10–20 keV deconvolved NuSTAR data (in green). We have convolved the Chandra image with a Gaussian function to match the resolution of the NuSTAR image. As the emission in the 10–20 keV band is almost exclusively non-thermal, locations where the 4–6 keV emission is coincident indicates that the latter is also non-thermal in nature.
