1. 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
2. Stars Eating Planets
Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : In a phase of instability during the dynamical evolution of some multiple exoplanetary systems, exchange of angular momentum and/or energy through gravitational interactions between planets will lead to alterations of their orbital properties. In some cases, planetary orbits end up crossing, which leads to close encounters between two planets. LÄS MER
3. High resolution imaging observations of exoplanet host stars
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : This is a thesis project, analysing data from high-resolution imaging observations, specifically speckle imaging, as a follow up study of exoplanet host stars observed with K2, the second operational phase of the space telescope Kepler. The project was accomplished at NASA Ames research center under the guidance of Rachel A. LÄS MER
4. Unfolding of multivariate tools and statistical analysis for Higgs boson pair production searches in the ATLAS detector at the Large Hadron Collider
Master-uppsats, Uppsala universitet/HögenergifysikSammanfattning : Recently, searches for pair production of Higgs bosons in several final states have been carried out by the ATLAS exeperiment at the Large Hadron Collider (LHC). This study focuses on the search for non-resonant di-Higgs production decaying to a final state with two b-jets and two τ-leptons using 36.1 fb-1 of data recorded by the ATLAS detector. LÄS MER
5. Performance of jet subtraction in pPb and PbPb collisions, without collectivity
Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationSammanfattning : We investigated the performance of basic jet subtraction, by the utilization of jet reconstruction generally used at the Large Hadron Collider (LHC). This was done by studying Z-bosons, in the dielectron decay channel, and the associated jet correlation in pp, pPb and PbPb collisions, using datasets generated by the Monte Carlo generator PYTHIA8.
