II.2 Diffusive shock acceleration<br />

● We again obtain a power law, but unlike other Fermi processes the<br />

slope is fixed<br />

● to verify the slope a, we can look at the synchrotron emission<br />

­ if the initial spectum is a power law, the synchrotron spectrum<br />

will be a power law with slope<br />

= a−1<br />

2 =0.5
