Methods of extragalactic distance measurements. Morfologz, kinetics and dynamics of Milkz way discussion. Classification of galaxies. Origin and evolution of largescale structures in the expanding universe.
Syllabus
  • Historical introduvtion, star counting, Hubble expansion.
    Milky way - morfology kinematics and dynamics black hole at centre of Milky way (Sgr A*)
    World of galaxies - spirál galaxies, eliptical galaxies, Hubble classification.

    Elliptical galaxies - classification surface brightness profilw composition dynamics.
    Scaling relations - Tully-Fisher and Faber-Jackson relations.
    Black holes at centres of galaxies -Schwarzchild radius radius of influenece kinematical evidence examples of supermassive blackholes in galaxies corelation between mass of supermassive black holes and proferties of galaxies,
    Extragalactic distances - distance ladder Cepheides, SN Ia, galaxies surface brightness scaling relations.
    Galaxies as gravitational lens - gravitational lensing simple models (point mass, isotermal sphere) applicaton (determination of lens mass distribution, determination of Hubble constant).
