  1. 16. The Metallicity Structure of the Milky Way Halo II : Characterising the distant halo substructure

    Master-uppsats, Uppsala universitet/Observationell astrofysik

    Författare :Amanda Byström; [2022]
    Nyckelord :Milky Way; Galactic archaeology; halo; photometric metallicities; stellar catalogue; Gaia-Enceladus-Sausage; Sagittarius; Pristine survey; metallicity; Gaia mission;

    Sammanfattning : The Milky Way galaxy, like all spiral galaxies, is surrounded by a roughly spherical distribution of stars called the halo. The halo was largely formed when the galaxy merged with smaller galaxies. LÄS MER

  3. 17. On The Run: How Fast Runaway Stars Can Escape From Their Home Cluster?

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Anna-Maria Söderman; [2022]
    Nyckelord :star cluster; runaway stars; velocity distribution; Physics and Astronomy;

    Sammanfattning : Galaxies contain a wide variety of star clusters with different properties. Each cluster is a possible source of runaway stars, which can be progenitors of supernovae in other parts of the galaxy than their home cluster. Considering runaway stars in galaxy simulations has shown to increase the galactic feedback. LÄS MER

  4. 18. Brightest Cluster Galaxies in the Local Universe: Mergers, Interactions and the Implications for Galaxy Evolution

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Diane Delley; [2022]
    Nyckelord :Brightest Cluster Gallaxies; BCG; Cosmology; Clusters of Galaxies; Merger; Interaction;

    Sammanfattning : Clusters of Galaxies are amongst the largest gravitationally bound structures in our Universe and consist of thousands of galaxies. It is in these gigantic systems where Brightest Cluster Galaxies (BCGs) are found, the most massive galaxies in our Universe. A BCG, as its name indicates, is the brightest galaxy in a cluster.

  5. 19. High Redshift Galaxies with JWST and Euclid

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Emma Lundqvist; [2022]
    Nyckelord :jwst; euclid; high redshift galaxies; early galaxies; GalaxyMC; jwst; euclid; tidiga galaxer; GalaxyMC;

    Sammanfattning : This projects studies which early galaxy populations will be visible using the telescopes JWST and Euclid. Galaxy luminosity functions are calculated for different redshifts, with the galaxy number density as a function of apparent magnitude. The apparent magnitude is used to enable easy comparisons with the observational limits of JWST and Euclid. LÄS MER

  7. 20. The Rotational Centre of the Large Magellanic Cloud

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Alma Bergström; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The Large and Small Magellanic Clouds (LMC & SMC) are the two largest galaxies orbiting the Milky Way (MW). The interactions between them have affected the evolution of both galaxies. The interactions have affected the galaxies differently depending on how strong they have been. LÄS MER
