U ovoj disertaciji predstavljeno je formiranje struktura usled sudara dve galaksije, pričemu je jedna galaksija velika spiralna galaksija, a druga patuljasta galaksija koja je njen satelit...

n this dissertation, we presented galaxy mergers and the forming of stellar morpholo- gical substructures. We assume a large spiral galaxy and dwarf galaxy which is a satellite of the first one. We used N-body simulations to present different scenarios for the mer- ger of two galaxies, and after that, we analyzed the properties of formed structures. The investigation of the formation of these structures and their properties is important for understanding the dynamics and evolution of galaxies...
