  1. 1. Chariots of the Atlantic Warriors - A Comparative Study of Chariot Motifs on Scandinavian and Iberian Rock Art

    Master-uppsats,

    Författare :Hannes Grahn; [2023-03-17]
    Nyckelord :Bronze Age; Rock art; Chariots; Scandinavia; Iberia; Long-distance interaction; Frännarp; Kivik; Villfara; Iberian warrior stele;

    Sammanfattning : During the last two decades, ideas of long-distance interaction between cultures has gained an increased amount of attention in the field of Bronze Age research. Previous research has shown that such a long-distance interaction, connected to the trade of metal and amber, may have existed between Scandinavia and Iberia, facilitated by a group of seafaring warrior-traders, with a shared identity, set of values and cosmology.

  3. 2. Finding new members of the VelHel-4 stream

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Lucas Johansson; [2023]
    Nyckelord :Galactic Archaeology; Milky Way; Stellar Streams; Streams; Stellar Halo; Stars; Globular Cluster; Astronomy; Astrophysics; Gaia; Chemical Abundance; Spectroscopy;

    Sammanfattning : According to the paradigm of lambda-CDM cosmology, the stellar halo ofour Galaxy has been built-up over time through the accretion of other galaxiesand star clusters. The remnants of some of these are still observable today asstellar streams, but are typically very faint and difficult to resolve amidst the farmore numerous foreground Milky Way stars. LÄS MER

  4. 3. Warm dark matter simulations and 21cm astronomy

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Melker Marminge; [2023]
    Nyckelord :Warm Dark Matter; N-body Simulation; Power Spectrum; Neutral Hydrogen; Cosmology;

    Sammanfattning : The recent boom in 21cm astronomy has piqued the interest of many, especially cosmologists realizing its applications in their field. This study aims to determine if 21cm astronomy is a good tool for testing the validity of keV WDM models, as well as creating a code capable of simulating keV WDM models from an existing CDM code.

  7. 5. The Inflationary Universe

    Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Benjamin Cavcic; [2023]
    Nyckelord :general relativity; inflation; cosmology; cosmic inflation; chaotic inflation; natural inflation; eternal inflation; valley hybrid inflation;

    Sammanfattning : Astrophysical observations of the cosmic microwave background point to inconsistencies in the standard model of cosmology, and a primordial accelerated expansion of the universe known as inflation has been suggested as a solution. Unfortunately, observational evidence of inflation is lacking, and there exists hundreds of models that populate the inflationary landscape. LÄS MER
