Information

Aims, contents and method of the course

For our understanding of astrophysical processes acting on galaxies, the low-mass and faint satellite galaxies around massive Hubble-type objects serve as the fundamental link to the formation of cosmological objects. In addition to already known Dwarf Galaxies in the Milky Way vicinity more and more new companions down to the lowest mass range of ultra-faint dwarf galaxies (UFDs) are found by advanced observational methods. Moreover, also around other massive galaxies satellite systems are detected with various properties. as e.g. ultra-compact dwarfs (UCGs) in galaxy clusters. On the one hand, satellite galaxies are considered as building blocks of massive galaxies and play a decissive role in our cosmological understanding what also means that a large number of them are already accreted by the central galaxy. On the other hand, satellite galaxies are formed continuously within the tidal arms of interacting galaxies, what also means that these Tidal Dwarf Galaxies (TDGs) must be DarK Matter free, while their properties agree well with regular dwarf galaxies.
This course is dedicated to the formation and evolution of satellite galaxies and will study star-formation history, element abundances, and properties of their various types under the aspect that they commonly evolve in the tidal field of massive galaxies.
This course will be held in English!
