  1. 11. The Metallicity Structure of the Milky Way Halo II : Characterising the distant halo substructure

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Amanda Byström; [2022]
    Keywords : Milky Way; Galactic archaeology; halo; photometric metallicities; stellar catalogue; Gaia-Enceladus-Sausage; Sagittarius; Pristine survey; metallicity; Gaia mission;

    Abstract : The Milky Way galaxy, like all spiral galaxies, is surrounded by a roughly spherical distribution of stars called the halo. The halo was largely formed when the galaxy merged with smaller galaxies. READ MORE

  3. 12. Brightest Cluster Galaxies in the Local Universe: Mergers, Interactions and the Implications for Galaxy Evolution

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Diane Delley; [2022]
    Keywords : Brightest Cluster Gallaxies; BCG; Cosmology; Clusters of Galaxies; Merger; Interaction;

    Abstract : Clusters of Galaxies are amongst the largest gravitationally bound structures in our Universe and consist of thousands of galaxies. It is in these gigantic systems where Brightest Cluster Galaxies (BCGs) are found, the most massive galaxies in our Universe. A BCG, as its name indicates, is the brightest galaxy in a cluster.

  4. 13. Coastal Response to Sea Level Rise in Ystad Municipality

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Elin Olsson; Sara Engström; [2021]
    Keywords : coastal erosion; Bruun Rule; sea level rise; coastal management; beach morphology; coastal processes; Technology and Engineering;

    Abstract : The globally accelerating sea-level rise poses a problem in coastal areas through, e.g., the erosion of sandy beaches. Due to this, buildings, infrastructure, and other values can be lost, making the future shoreline position important to project in coastal management. READ MORE

  5. 14. The hydrodynamic impacts of Estuarine Oyster reefs, and the application of drone technology to this study

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Oskar Evert Johansson; [2021]
    Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Oyster Reef; Drone; UAV; Hydrodynamics; Earth and Environmental Sciences;

    Abstract : The impacts of climate change are being seen within the estuarine environment through erosion and shoreline retreat, associated with sea-level rise and changes in storm activity. Restoration oyster reefs have been identified as a working-with-nature strategy to protect and restore these shoreline environments, stabilising sediment, and reducing erosion. READ MORE

  6. 15. Determining and analysing production losses due to ice on wind turbines using SCADA data

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Oscar Felding; [2021]
    Keywords : Wind turbines; ice accretion; ice losses; SCADA; cold climate; Vindturbin; ispåbyggnad; isförluster; SCADA-data; kallt klimat;

    Abstract : Wind turbines are becoming a more common sight and a more important part in the power grid. The benefits are mainly that wind energy is a renewable energy source and a single wind turbine can produce enough electricity to cover several households’ annual electricity need and not producing carbon dioxide as a rest product.
