  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. Characterization of Lamps of IRF Solar Simulator

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Mrunmayee Sonna; [2023]
    Keywords : IRF; Solar simulator; Characterization; Thermal simulations; Systema-Thermica; Autodesk Inventor; correlated results;

    Abstract : The Swedish Institute of Space Physics (IRF) at Kiruna focuses on research activities in the ionosphere, magnetosphere, and upper atmosphere of the planet as well as the development and production of various sensors and detectors for space research. The test facility includes the IRF SpaceLab which is equipped with multiple testing equipment. READ MORE

  4. 3. 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.

  5. 4. Investigation of Antenna Radomes in Low Earth Orbits

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Mathias Manohar Gren; [2023]
    Keywords : Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Abstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  6. 5. Phase Transitions in the Two-Higgs-Doublet Model with a Softly-Broken Z2 Symmetry

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Filip Gustavsson; [2023]
    Keywords : Particle Physics; Beyond Standard Model; Two-Higgs Doublet Model; 2HDM; Electroweak Phase Transitions; Strong First-order Phase Transition; Dimensional Reduction; CP-conserving; Softly broken Z2-symmetry; Physics and Astronomy;

    Abstract : The two-Higgs-doublet model (2HDM) is an extension to the Standard Model which adds a second Higgs doublet. This extension provides freedom within the model, in comparison to the Standard Model, which makes it possible to study strong electroweak phase transitions. READ MORE
