  1. 1. Analyzing the dust of the Nearby Universe

    Master-uppsats, Uppsala universitet/Observationell astrofysik

    Författare :Jimmy Kjellqvist; [2021]
    Nyckelord :Intergalactic dust; cosmology; cosmological measurements; quasars; Intergalaktiskt stoft; kosmologi; kosmologiska mätningar; kvasarer;

    Sammanfattning : The aim of this master thesis is to investigate the influence of intergalactic duston astronomical observations. The current cosmological paradigm of an acceleratingcosmic expansion is supported by observations of Type Ia supernovae. LÄS MER

  2. 2. Death's reflection in the water : Mortuary ritual, ancestral worship and the cosmological significance of water on the island of Gotland during the Pitted Ware culture

    Kandidat-uppsats, Uppsala universitet/Arkeologi

    Författare :Maja Hed; [2021]
    Nyckelord :ritual; neolithic; grave goods; cosmology; flowing water; divinity; death; Pitted Ware culture; ritual; neolitikum; gravgåvor; kosmologi; rörligt vatten; gudomlighet; död; Gropkeramisk kultur;

    Sammanfattning : The Pitted Ware culture on Gotland presents a multitude of material that allow archeologists to re-construct and visit the socio-economic structure of a middle-neolithic settlement in the Baltic sea. I will be analyzing the archaeological material in accordance to the ocean, and to what we can interpret as ritual and cosmological variables at the site through ritual theory, and with a method of comparative analogy and research.

  3. 3. Galaxies as Clocks and the Universal Expansion

    Master-uppsats, KTH/Fysik

    Författare :Anders Ahlström Kjerrgren; [2021]
    Nyckelord :cosmology; cosmic chronometers; universal expansion; Hubble parameter; differential ages; galaxy age; relative age; cosmic time; chi-square minimization; monte carlo sampling; gaussian processes; kosmologi; kosmisk kronometer; universums expansion; Hubbleparametern; differentiell ålder; galaxålder; relativ ålder; kosmisk tid; chi-2-minimering; monte carlo-sampling; gaussiska processer;

    Sammanfattning : The Hubble parameter H(z) is a measure of the expansion rate of the universe at redshift z. One method to determine it relies on inferring the slope of the redshift with respect to cosmic time, where galaxy ages can be used as a proxy for the latter. This method is used by Simon et al.

  4. 4. A Machine Learning Approach for Comprehending Cosmic Expansion

    Master-uppsats, KTH/Fysik

    Författare :Ludvig Doeser; [2021]
    Nyckelord :Cosmology; Cosmic expansion; Galaxy Images; Machine learning; Kosmologi; kosmisk expansion; galaxbilder; maskininlärning;

    Sammanfattning : This thesis aims at using novel machine learning techniques to test the dynamics of the Universe via the cosmological redshift-distance test. Currently, one of the most outstanding questions in cosmology is the physical cause of the accelerating cosmic expansion observed with supernovae. LÄS MER

  5. 5. Sanfolkets transformativa kunskapsprocesser : En kvalitativ analys av sanfolkets existentiella riter ur ett dramapedagogiskt perspektiv

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för humaniora

    Författare :Ottilia Söderström; [2021]
    Nyckelord :San people; Ju ’hoansi; Drama as education; Transformative knowledge processes; Ritual studies; Performance studies; Anthropology of religion; Sanfolket; Ju ’hoansi; Dramapedagogik; Transformativa kunskapsprocesser; Ritualstudier; Performancestudier; Religionsantropologi;

    Sammanfattning : Studien syftar till att analysera sanfolkets existentiella riter och transformativa processer ur ett dramapedagogiskt perspektiv. Bakgrunden avgränsas till att undersöka och redogöra för Ju/’hoansifolkets etnografi, kosmologi samt riter med fokusering på de transformativa processerna. LÄS MER
