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
  • South Pole Telescope survey image
  • Dark Energy Survey cluster followup

Plasma Effects

• basics: see notes by Richard Fitzpatrick
• plasma frequency
• dispersion and dispersion measure
  • awesome example: pulsars
  • typical radio signals, distribution on sky
  • free electron density map from pulsar ensemble
• Faraday rotation: in the Milky Way, in M31
• Cerenkov radiation
