1. Finding stars that are likely to be from accreted satellite galaxies
Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : The Milky Way galaxy has through its lifetime merged with several smaller galaxies in its surroundings. Merger events like these play an important role in the formation of galaxies and are therefore of great interest to better our understanding of galaxy formation. LÄS MER
2. The Metallicity Structure of the Milky Way Halo II : Characterising the distant halo substructure
Master-uppsats, Uppsala universitet/Observationell astrofysikSammanfattning : 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. Archaeologic inspection of the Milky Way using vibrations of a fossil : Seismic, spectroscopic and kinematic characterization of a binary metal-poor Halo star
Kandidat-uppsats, Uppsala universitet/Observationell astrofysikSammanfattning : The Milky Way has undergone several mergers with other galaxies during its lifetime. The mergers have been identified via stellar debris in the Halo of the Milky Way. The practice of mapping these mergers is called galactic archaeology. To perform this archaeologic inspection, three stellar features must be mapped: chemistry, kinematics and age. LÄS MER
