1. Can Dwarf Galaxies Tell Us How the Milky Way Formed?
Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : Dwarf galaxies are a key component in understanding the evolution of galaxies and provide tests on the standard cosmological $\Lambda$ Cold Dark Matter model. According to the formation hierarchy, dwarf galaxies are the pieces that create all galaxies. Our current understanding of dwarf galaxies faces discrepancies between theory and observations. LÄS MER
2. Planes of satellite galaxies
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : The Planes of Satellites Problem is an open question within the field of galaxy formation. It is based on the observations that the Milky Way's satellites, as well as those around the Andromeda (M31) galaxy, align in planes. LÄS MER
3. Background Studies of the High-Intensity Baryon Extraction and Measurement (HIBEAM) Experiment at the European Spallation Source
Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : The High-Intensity Baryon Extraction and Measurement experiment (HIBEAM) is proposed as one of the experimental stations at the European Spallation Source (ESS). This experiment will mainly focus on the neutron into sterile neutron oscillations which violate the baryon number (B) by one unit. LÄS MER
4. Cosmic Dawn in a Fuzzy Universe : Constraining the nature of Dark Matterwith 21 cm Cosmology
Kandidat-uppsats, Stockholms universitet/Institutionen för astronomiSammanfattning : The cold dark matter (CDM) paradigm underlying the standard CDM model of cosmology is successful on large scales but faces potential problems on small scales partly related to a seeming overproduction of dwarf galaxies. This could be alleviated in exotic dark matter models that suppresses small-scale structure formation. LÄS MER
5. Mass models and the spiral arms of the Milky Way
Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationSammanfattning : I investigate to what extent spiral arms might affect axisymmetric Galactic models. As we need fully dynamical and high resolution Galactic evolutionary models to probe the structure of the dark matter halo, it is important that we use accurate mass models describing the MW structure.
