1. The Metallicity Structure of the Milky Way Halo II : Characterising the distant halo substructure
University essay from Uppsala universitet/Observationell astrofysikAbstract : 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. READ MORE

2. The Metallicity Structure of the Milky Way halo I : Creating a stellar catalogue of the distant halo’s red giants
University essay from Uppsala universitet/Observationell astrofysikAbstract : The Milky Way's halo is an approximately spherical distribution of stars surrounding the Galaxy that carries the history of the Milky Way. The outer halo is a Galactic region with long dynamical timescales largely built up by accreted material. READ MORE

3. Archaeologic inspection of the Milky Way using vibrations of a fossil : Seismic, spectroscopic and kinematic characterization of a binary metal-poor Halo star
University essay from Uppsala universitet/Observationell astrofysikAbstract : 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. READ MORE

4. Lightcurves of super-Chandrasekhar mass supernovae
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : 20 supernovae that spectroscopically match the peculiar, superluminous type Ia supernova 2003fg are studied in this project. SN2003fg is thought to have erupted at a super-Chandrasekhar mass, thus breaching the theoretical mass limit for a white dwarf. READ MORE
