Learning outcomes

Student can describe structural, dynamical, chemical and dark matter differences between elliptical, spiral and dwarf galaxies. Student can describe the significance of the mergers, interactions for the evolution of galaxies. Student can explain relation between black holes and nuclei activity. Student can estimate masses of galaxy clusters.

The student can explain Friedmann's cosmological model as the basis for study of the evolution and matter-energy contents of the universe. She/He can use Friedmann's model as an instrument to make a variety of cosmological calculations. He/She can explain the basic structure formation theory of the universe starting from initial quantum fluctuations through different cosmic epochs. Student can explain formation of the cosmic microwave radiation and it's theoretical and observational significance.


Stellar contents and morphological and dynamical properties of different galaxy types in Hubble sequence. Inter stellar medium, statistics of galaxies and environments. Dark matter halos of galaxies. Dwarf Galaxies and other low luminosity systems. Mergers and Interactions.
Radio Galaxies and Active Galactic Nuclei. Super massive black holes, galaxy clusters. Observational tests and evidence for galaxy formation and evolution.

Robertson-Walker metric, Mattig's equation and cosmological distances, cosmological tests, the physical nature of the dark energy and dark matter, horizons in cosmology, inflation, primordial spectrum of fluctuations, evolution of the matter power spectrum, quantitative measures of the large-scale structure, physics of cosmic thermal background radiation, linear growth of fluctuations and structure formation, spherical top-hat model, non-linear structure formation and cosmological simulations.
