  • The Global ETD Search service is a free service for researchers to find electronic theses and dissertations. This service is provided by the Networked Digital Library of Theses and Dissertations.
    Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Slupkové galaxie - hydrodynamické simulace typu "sticky-particles" / Shell galaxies - "sticky particles" hydrodynamical simulations

Zimandl, Martin January 2015 (has links)
Shell galaxies are usually ellipticals with concentric faint arc-like stellar structures with sharp outer edges. They originate from galactic collisions (so called mergers). According to observations, some galaxies has also gaseous structures, that can be associated with stellar shells. We carry out a few numerical simulations, in which we recreate gaseous shells throug radial collisions of small and large elliptical galaxies. Then we analyze the differences between stellar and gaseous shells. Our simulations are based on earlier models, which describes gas by using so called "sticky-particles" hydrodynamics. This approach was so far quite succesful in resolving origin of gaseous shells. Our conclusion is, that gas in preset galaxies is not sufficient to make any difference. Higher quantities on the other hand has significant effect. Powered by TCPDF (www.tcpdf.org)
