1. Black Hole Dynamics in Stellar Clusters
Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster.

2. Simulating and Testing the Polarimetric Response of the X-ray Polarimetry Telescope XL-Calibur
Master-uppsats, KTH/FysikSammanfattning : X-ray polarimetry, the study of the polarisation of X-ray light, is a powerful and rapidly developing tool for astrophysics, which promises to help answer outstanding questions about the physics of extreme objects such as pulsars, X-ray binaries and active galactic nuclei. The balloon-borne telescope XL-Calibur will be the first instrument to study the polarisation of hard X-rays (with energies between 10 and 100 keV) in detail, correlating with the soft X-ray observations of IXPE to provide further tests of polarisation-dependent x-ray emission models in extreme objects.

3. Chaos in Stellar Dynamics - Outcomes of Binary-Single interactions in Globular Clusters
Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationSammanfattning : Gravitational encounters between a single star and a binary system can frequently occur in the cores of dense stellar systems like globular clusters. These three-body scattering encounters can lead to a variety of outcomes since the energy of the binary components can be exchanged with the interacting single star. LÄS MER
4. Investigating super-Eddington accretion flows in Ultraluminous X-ray sources
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : It is now widely known that most of the large galaxies we observe (e.g. the Milky Way) host in their center a supermassive black hole ($10^{6}-10^{9}$ $M_\odot$). LÄS MER
5. Investigating Black Hole Kicks
Magister-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : It has been known for some time that neutron stars receive kicks (so-called natal kicks) when they are formed in core-collapse supernovae. Whether black holes receive these kicks too is still a matter of debate. LÄS MER
