  1. 6. Att förena de oförenliga: Är både vänster och högerradikala partier nationalistiska? En kvantitativ undersökning av europartiers nationalism.

    Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Nils Karlsson; [2020]
    Nyckelord :Europartier; Nationalism; Hästskoteorin; Radikala partier; Kvantitativ innehållsanalys; Law and Political Science;

    Sammanfattning : This paper studies nationalism within radical europarties. Europarties are in turn parties at the European level which consist of multiple national parties. LÄS MER

  3. 7. Lyman Continuum Radiation from Intermediate-Mass Black Holes : An Estimation of the Contribution of LyC Radiation from IMBHs in z~3 Galaxies

    Kandidat-uppsats, Uppsala universitet/Observationell astrofysik

    Författare :Marika Ljungberg; [2020]
    Nyckelord :intermediate-mass black holes; cosmic reionization; high-redshift galaxies;

    Sammanfattning : This thesis concerns the cosmic reionization of the intergalactic medium in the high redshift universe and, in particular, is a first approach to examine what role intermediate mass black holes (IMBHs) play in this cosmic age. Unexpectedly high values of hydrogen ionizing radiation, compared to current models, have been reported from galaxies at redshift ~3 (used as stand-ins for galaxies at the age of reionization), and thus these models need revision, potentially by adding effects of IMBH content in the galaxies.

  4. 8. Original: X-ray Spectral Analysis of a Serendipitously Observed Active Galactic Nucleus

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

    Författare :Teodor Elmfeldt; Filip af Malmborg; [2020]
    Nyckelord :;

    Sammanfattning : An active galactic nucleus (AGN) is a region in the center of a galaxy with a supermassive black hole continuosly accreting material. This accretion gives rise to large amounts of radiation across the whole electromagnetic spectrum, and largely affects the regions around the AGN and the evolution of the whole galaxy. LÄS MER

  5. 9. Study of the in-flight calibration of theSVOM/ECLAIRs instrument

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Jakob Östberg; [2020]
    Nyckelord :Telescope; calibration; gamma-ray; burst; ECLAIRs; SVOM; IRAP;

    Sammanfattning : The Space based multi-band Variable astronomical Object Monitor (SVOM) is a x- andgamma-ray telescope with the primary objective of observing gamma-ray bursts. Themission is a cooperation between the French and Chinese space agencies and will be launchedin 2021. LÄS MER

  7. 10. Iron-Based Dye-Sensitized Solar Cells - From Theory to Working Solar Cell

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Linnea Lindh; [2019]
    Nyckelord :Dye-sensitized solar cells; Grätzel cells; solar cells of the future; solar cells of tomorrow; spectroscopy; time-resolved spectroscopy; materials chemistry; materialkemi; Chemistry;

    Sammanfattning : In the hunt for fossile-free energy-harvesting techniques, solar cells constitute one of the most promising techniques. Today, silicon-based solar cells are the dominant technique on the market but even the Silicon solar cell has limitations which means that there is a motivation for developing new solutions. LÄS MER
