  1. 1. The visibility of stellar transients in the Galactic Centre

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

    Author : Jonathan Ström; [2024]
    Keywords : Physics and Astronomy;

    Abstract : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. READ MORE

  3. 2. 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.

  4. 3. Near Field millimeter Wave Antenna Measurements

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Bharath Manjunatha; [2023]
    Keywords : Antenna Pattern; Near field to far field; Planar Scanning; Probe Compensation; Active Antenna; Technology and Engineering;

    Abstract : In the real world, understanding an antenna's radiation pattern is crucial for its proper utilization. Typically, antennas are tested in the far-field region, where the radiation lobes are fully developed and phase errors are less than pi/8. READ MORE

  5. 4. Across the Øresund: A narrative case study of the connections between national borders and national sentiments in a European cross-border region

    University essay from Lunds universitet/Europastudier

    Author : Denise Nilsson; [2022]
    Keywords : Cross-border; National Sentiments; Narrative Policy Framework; Regional narratives; Borders; Cross-border integration; Territoriality; Øresund; Greater Copenhagen; European Studies; Social Sciences;

    Abstract : Within the field of border studies, a common theoretical assumption is that national borders and national sentiments are interconnected. Some even argue that national boundaries are a precondition of national sentiments (Anderson & O'Dowd, 1999; Paasi, 1998 (b)). READ MORE

  6. 5. X-Ray Fluorescence of Metal Halide Perovskites

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

    Author : Samuel Narciso Silva; [2022]
    Keywords : Perovskite; X-ray; Fluorescence; Python; PyMCA; Synchrotron radiation; Physics and Astronomy;

    Abstract : This thesis has the aim to provide a framework for analyzing X-ray fluorescence (XRF) data obtained from German Electron-Synchrotron Group (DESY). The theoretical analysis shows that XRF competes with Auger emission, and works mainly for elements with high atomic number. Here, incident X-rays of 13. READ MORE
