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

Awesome Example: Fast Radio Bursts

• new, fast-moving field! reviews: Petroff, Hessels, & Lormier (2019) and (2022)
• example light curves
• example of burst dynamic spectrum
• dispersion measures vs pulsars
• sky distribution
