Thompson Scattering

• angular distribution, total power
• cross section
• polarization
• awesomest Thomson polarization example--CMB:
  theory and WMAP stacked data compared

Bremsstrahlung: Free-Free Emission

• Order of Magnitude Expectations
• Theory: Classical, Non-Relativistic Case
• example: intracluster medium
  • galaxy clusters seen in optical light: Virgo, Coma, Abell 1689
  • intracluster medium seen in X-rays: Virgo, Coma, Abell 1689
