Learning Outcomes 1. Appraise the use of a variety of models for the dynamics of plasmas in different astrophysical systems 2. Identify the key assumptions in deriving the shock relations in plasmas 3. Summarise the primary process by which non-thermal particles are accelerated. 4. Identify and describe radiative processes leading to the observed X-ray and gamma-ray emission. 5. Differentiate between the various radiative processes relevant to a variety of astrophysical systems | |||||||||||||||||||||||||||||||||||||||||
