Inverse Compton Emission

• cross section and energy transfer: ordinary kinematics
• inverse Compton power: single electron
• inverse Compton spectrum: single electron
• power-law electron spectra

Awesome Example: Fermi Bubbles

• large-scale features at 1 GeV
• foreshadowed by WMAP haze, now also seen by Planck

Inverse Compton Scattering Awesome Example: Sunyaev-Zeldovich Effect

• introduction to the CMB
• thermal SZ physics:
  • Compton-y
  • frequency distortion
• SZ observations:
  • temperature maps: Coma cluster, clusters across redshifts, Abell 2319 across frequencies,
  • frequency spectrum
• SZ cosmological applications
