Sammanfattning : Chameleons are scalar fields coming from modied gravity theories and can be possible explanations for Dark Energy. They cause a fifth force and have a screening mechanism which allows this force to avoid solar system constraints. In this thesis, astrophysical consequences of the potential presence of the chameleon field will be studied. LÄS MER

Sammanfattning : The globular cluster population of large spiral galaxies can be divided into two populations: one population which formed in-situ and one which has been assembled through capture of clusters that have been tidally stripped away from other galaxies during close encounters or mergers. In this work, I focus on the globular cluster MGC1, which is orbiting the M31 galaxy. LÄS MER

Sammanfattning : There is compelling evidence that dark matter constitutes 85 % of theuniverse's total matter content. So far, this distinctly different type ofparticle is observed only in terms of its gravitational effects, but variousdetection experiments are conducted and underway. One methodis indirect detection of neutrinos coming from the Sun. LÄS MER

Sammanfattning : I simulate the collision of satellite galaxies with the Milky Way and observe the effects that this has on the orbits of the globular cluster populations within both the Milky Way and the satellite galaxies. This is done in order to investigate whether some of the Milky Way's globular clusters could have been donated from satellite galaxies which have been tidally stripped, since it is believed that the Sagittarius dwarf spheroidal galaxy is being tidally disrupted and that some of its globular clusters have been tidally stripped from it (such as Pal 12 and NGC 4147).
