  1. 1. Potassium in the Galactic Bulge - as traced by microlensed dwarf & sub-giant stars

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Lukas Jönsson; [2023]
    Keywords : Nucleosynthesis; Galactic Bulge; Potassium; Non-Local-Thermal-Equilibrium; Physics and Astronomy;

    Abstract : During this report the potassium (K) trend in the Galactic Bulge, with respect to metallicity and various α-elements, has been computed and evaluated by a method of line synthesis on the 7698.96 ̊A KI line (7699 KI), where Non-Local-Thermal-Equilibrium (NLTE) effects have been considered.

  3. 2. Defining dark jets at the particle level

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Gustav Lindberg; [2023]
    Keywords : Particle physics; Dark matter; QCD; Physics and Astronomy;

    Abstract : One hypothesis that attempts to explain dark matter is dark QCD, which suggests that there would be a dark sector made up of dark quarks. Dark quarks would interact with each other through dark QCD similar to how Standard Model quarks interact with each other through Standard Model QCD. READ MORE

  4. 3. Rising Stars: Unleashing the Entrepreneurial Drive of Generation Z : An Exploratory Qualitative Case Study On Entrepreneurial Motivation of Generation Z

    University essay from Jönköping University/IHH, Företagsekonomi

    Author : Julia de Geus; Lina Wennberg; [2023]
    Keywords : Entrepreneurship; Generation Z; Motivation;

    Abstract : Background: From 2020 onwards the business environment has changed more than ever, and a new generation is making its way into the workforce. After the Covid-19 pandemic and digitalization created a new normal with hybrid and remote working structures, the wish for flexibility in the work environment has increased among Generation Z.

  5. 4. The tangled Warp of the Milky Way

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Viktor Hrannar Jónsson; [2023]
    Keywords : Galaxy: structure; Galaxy: kinematics and dynamics; Galaxy: disk; Galaxy: evolution; Physics and Astronomy;

    Abstract : Context: The Milky Way disc, like the discs of many other spiral galaxies, has been shown to be warped. The growing astrometric data set for stars produced by the Gaia mission allows for more detailed studies of the stellar disc's warp. READ MORE

  6. 5. Focal Spot Optimization Using Spatial Light Modulation and a Phase Retrieval Algorithm

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Robert Petersen; [2023]
    Keywords : Spatial Light Modulation; Phase Retrieval Algorithm; Focal Spot Optimization; Adaptive Optics; Wavefront Sensing; Lasers; Physics and Astronomy; Technology and Engineering;

    Abstract : Aberrations to the wavefront of a laser beam reduce the quality of the focal spot and are generally undesired. This project is aimed at determining the aberrations of laser beams by using a phase retrieval algorithm and to show that it is possible to correct the aberrations with a spatial light modulator to optimize the focal spot.
