We report the first localization of diffuse , non-thermal , X-ray emission from a nearby galaxy cluster .
Using Chandra data , we have isolated a diffuse non-thermal X-ray component with a photon index , \Gamma _ { X } = 2.21 ^ { +0.14 } _ { -0.15 } and a flux of 9.5 ^ { +1.1 } _ { -2.5 } \times 10 ^ { -5 } photons cm ^ { -2 } s ^ { -1 } keV ^ { -1 } at 1 keV , that extends from \sim 1 \arcmin .5 to \sim 2 \arcmin .5 to the south of the X-ray flux peak .
Comparison to simulations implies that the diffuse non-thermal emission is produced by primary electrons , accelerated at shocks to relativistic velocities .
Using these results and the flux and hardness maps produced with data from the Chandra Advanced CCD Imaging Spectrometer , we conclude that a smaller subclump coming from the north merged with IC1262 .
The offset of the cD galaxy from the X-ray peak and large peculiar velocity indicate that the subclump ’ s impact parameter was to the west and on the near side of IC1262 .
