Cosmic electrodynamics.
Radiation of an accelerated charged particle; bremsstrahlung; opacity for
Thompson scattering and free-free absorption; Liouville's theorem and its implication for conservation of intensity along the light ray; raditive transfer equation; synchrotron radiation; Compton scattering and inverse
Compton scattering; Sunyaev-Zel'dovich effect
Basic model of pulsar - aligned rotator
Accretion process.
Particles and fluid in astrophysics - basic (hydro)dynamical equations; spherical steady-state accretion; star moving through a nebula - Bondi accretion; disc accretion, viscosity, boundary layer, spectrum; accretion on black holes; high accretion - accretion torus, hydrodynamics of rotating fluids; other models of accretion discs - vertically integrated (slim) discs;
S-diagram; conditions for thermal and viscous stability.
Active galactic nuclei.
Elementary observational facts about quasars and related objects; standard model of active gelectic nuclei; continuum and spectral lines, cheracteristic time and length scales.
