X-ray synchrotron emission in the SN 1006 supernova remnant (PCHE)
J. Ballet, R. Rothenflug, A. Decourchelle, P. Ferrando and G. Dubner
SN 1006 is the prototype of supernova remnants in which the X-ray
emission is dominated by synchrotron emission of cosmic-ray electrons.
With XMM-Newton, the X-ray emission is spatially resolved and the
spectral resolution allows to distinguish the synchrotron component from
the residual thermal component.
We have compared the X-ray data with radio data, to look for variations
of the shape of the synchrotron component.
We find strong azimuthal variations, which prove that the maximum energy
reached by the electrons is larger at the bright limbs (where the
magnetic field is supposedly tangential).
