  1. 1. Understanding the large-scale structure of the the21-cm signal originating from the Epoch of Reionisation

    Author : Ivelin Georgiev; Garrelt Mellema; Jens Jasche; Aurel Schneider; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; reionisation; cosmology; 21-cm; large-scale structure; Astronomy; astronomi;

    Abstract : The first billion years from the beginning of the Universe is the focus of multiple astronomical facilities in the upcoming decade. This unique era is marked by the formation of the first stars and galaxies, which release ionising radiation into the intergalactic medium(IGM). READ MORE

  2. 2. The fundamental structure of matter

    Author : Johan Hansson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Fysik;

    Abstract : The subject of this thesis is "the fundamental structure of matter, that is, the quest of understanding the deepest level of the physical world, and the interactions relevant at that level. The hope is that, as one goes deeper, the laws are going to be simpler, not necessarily in mathematical terms, but in conceptual terms. READ MORE

  3. 3. Physics-informed inferences of galaxy clustering with Bayesian forward modelling

    Author : Eleni Tsaprazi; Jens Jasche; Ariel Goobar; Alkistis Pourtsidou; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; large-scale structure; galaxy clustering; supernovae; Bayesian statistics; Physics; fysik;

    Abstract : In this thesis, we showcase four novel approaches to constraining the relationship between cosmological observables and the large-scale structure. The majority of the energy content of the Universe in the concordance cosmological model remains largely unknown. READ MORE

  4. 4. Weigh them all! : Cosmological searches for the neutrino mass scale and mass ordering

    Author : Sunny Vagnozzi; Katherine Freese; Lars Bergström; Alessandra Silvestri; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neutrinos; neutrino mass; neutrino mass ordering; cosmology; cosmic microwave background; large-scale structure; galaxy surveys; dark energy; cosmic inflation; data analysis; teoretisk fysik; Theoretical Physics;

    Abstract : The elusive neutrinos are among the most intriguing constituents of the particle zoo. The observation of neutrino flavour oscillations, indicating that neutrinos are massive, provides the only direct evidence for physics beyond the Standard Model. READ MORE

  5. 5. Lyman-alpha imaging of starburst galaxies in the local universe and beyond

    Author : Matthew Hayes; Göran Östlin; Matthew Lehnert; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy and astrophysics; Astronomi och astrofysik; Astronomy; astronomi;

    Abstract : The last decade has seen huge advances in studies of astrophysical cosmology, primarily as a result of developments in telescopic facilities. One of the primary observational signatures of actively star forming galaxies in the distant universe is the Lyman-alpha emission line (Lyα). READ MORE
