1. 1. Measuring copper abundances in the Galactic Bulge

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

   Author : Nikolei Höglinger; [2024]
   Keywords : Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

   Abstract : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

3. 2. Neutron backgrounds in neutrino-nucleus scattering at the European Spallation Source

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

   Author : José Guilherme Rodrigues de Albuquerque Vale; [2023]
   Keywords : Neutrino-nucleus scattering; background; PHITS; weight window; ESS; Physics and Astronomy;

   Abstract : Being, when built, the most powerful neutron accelerator in the world, there will be a large number of potential discoveries at the European Spallation Source (ESS) in Lund. One of the most exciting of these, from a particle physics point of view, is the Coherent Elastic Neutrino-Nucleus Scattering (CEνNS). READ MORE

4. 3. Illuminating the Dark : Measuring Emotional Experiences of Dark Tourism Consumers

   University essay from Linnéuniversitetet/Institutionen för marknadsföring och turismvetenskap (MTS)

   Author : Dana Szalaiova; Mark Vidrinskas; [2023]
   Keywords : Dark tourism; Dark Tourism Spectrum; Seven Dark Suppliers; emotions; emotional experiences; word-of-mouth;

   Abstract : This study examines the emotional experiences of 152 respondents visiting ‘light’, ‘lighter’, and ‘lightest’ dark tourism sites and the relationship those experiences have with positive word-of-mouth. Therefore, the theoretical contribution of this study fills in the research gap by focusing on the destinations on the ‘lighter’ periphery of Stone’s Dark Tourism Spectrum. READ MORE

5. 4. Feasibility Study of X-ray Free Electron Lasers in Fourth Generation Storage Rings

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

   Author : Jordis Hansen; [2023]
   Keywords : XFEL; Storage Ring; Synchrotron Radiation; Physics and Astronomy;

   Abstract : This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. READ MORE

6. 5. Origin of blue straggler stars in the Milky Way halo

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

   Author : Adam Brcek; [2023]
   Keywords : Blue Straggler; Galactic Halo; Spectroscopic Surveys; Binary Star Evolution; Mass Transfer; Physics and Astronomy;

   Abstract : Blue straggler stars (BSSs) are exotic stellar objects that appear to be younger than the age of the population they come from suggests. They are observed as the extension of the main sequence stars, beyond the turn-off point. READ MORE
