  1. 1. Real-Time Navigation for Swarms of Synthetic Aperture Radar (SAR) Satellites

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Antoni Eritja Olivella; [2024]
    Nyckelord :SAR; Real-time orbit determination; Real-time baseline determination; swarms; satellite; formation flying;

    Sammanfattning : The pursuit of precision and flexibility in satellite missions has led to an increased number of formation flying missions being developed. These systems consist of multiple satellites flying at close distances (from a few kilometres to a few meters) to achieve common objectives. LÄS MER

  3. 2. Observations of Field-Aligned Currents and Their Role in Auroral Formation

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Maxim Uebel; Nikolaos Timoudas; [2023]
    Nyckelord :;

    Sammanfattning : Experimentally, it has been difficult to identify the exact physical processes atwork in the magnetosphere that drive the strong currents that later give rise to auroras. Theaim of this report has been to address this question by analyzing data gathered from Cluster-,MMS-, and DMSP satellite missions. LÄS MER

  4. 3. Can Dwarf Galaxies Tell Us How the Milky Way Formed?

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Þóra Karlsdóttir; [2023]
    Nyckelord :Dwarf Galaxy; Milky Way; Physics and Astronomy;

    Sammanfattning : Dwarf galaxies are a key component in understanding the evolution of galaxies and provide tests on the standard cosmological $\Lambda$ Cold Dark Matter model. According to the formation hierarchy, dwarf galaxies are the pieces that create all galaxies. Our current understanding of dwarf galaxies faces discrepancies between theory and observations. LÄS MER

  5. 4. Finding stars that are likely to be from accreted satellite galaxies

    Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Helena Cronstedt; [2023]
    Nyckelord :galaxy mergers; merger debris; velocity space; Physics and Astronomy;

    Sammanfattning : The Milky Way galaxy has through its lifetime merged with several smaller galaxies in its surroundings. Merger events like these play an important role in the formation of galaxies and are therefore of great interest to better our understanding of galaxy formation. LÄS MER

  7. 5. Extreme precipitation events in the Sichuan Basin and their connection to mesoscale disturbances

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Anna Dugoul; [2022-10-04]
    Nyckelord :;

    Sammanfattning : The Sichuan Basin (SB) is a region with frequent extreme precipitation during summer, principally as a result of its location and topography, with the most extreme events possibly leading to floodings and landslides. A better understanding of these extreme events’ characteristics and triggers could help to improve forecasting methods, while improving the knowledge about climate dynamics in the region is crucial for climate change studies.
