  1. 1. Exploring New Physics Through Collider and Gravitational Wave Measurements with Artificial Neural Networks: the Case Study of QCD-like Technicolor

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Ashar Ahmed Kamal; [2023]
    Nyckelord :Artificial Neural Networks; ANN; Beyond the Standard Model; BSM; parameter space scan; Physics and Astronomy;

    Sammanfattning : With physicists actively exploring Beyond the Standard Model (BSM) theories that may fill in the gaps of the Standard Model (SM), a fundamental question arises: which parameters hold physical significance? In this thesis, we present our initial progress towards the development of a model-independent artificial intelligence framework designed for conducting parameter space scans in BSM scenarios. Our framework incorporates several publicly available high-energy physics packages, namely SPheno, HiggsBounds, HiggsSignals, and CosmoTransitions. LÄS MER

  3. 2. Void Evolution and Cosmic Star Formation

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

    Författare :Joel Wasserman; [2023]
    Nyckelord :Void; Void Evolution; Cosmic Void; Star Formation Rate; Star Formation History; Cosmic Star Formation; Cosmology; Spherical Evolution Model; SvdW; Vdn; Excursion Set Theory; Excursion Set Formalism; Astrophysics; Astronomy; Cosmic Web; Matter Transfer; Tomrum; Tomrumsutveckling; Kosmiska Tomrum; Stjärnbildningshastighet; Stjärnbildningshistorik; Kosmisk stjärnbildning; Kosmologi; Sfärisk Evolutionsmodell; SvdW; Vdn; Exkursionsset teori; Exkursionsset Formalism; Astrofysik; Astronomi; Kosmiska Spindelnätet; Masstransport;

    Sammanfattning : The rate at which stars have formed throughout the history of theuniverse is not constant, it started out slow, increased until around redshift ∼ 2 when it reversed and became slower again. The reason for this behaviour is still being investigated with various models and simulations usually based upon dark matter halos. LÄS MER

  4. 3. Järnålderns gudomliga tvillingar? : Mytologiskt tvillingskap i Skandinaviens materiella kultur

    Kandidat-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historia

    Författare :Chris Danielsson; [2022]
    Nyckelord :twins; the Divine Twins; Bronze Age; Iron Age; Scandinavia; cosmology; tvillingar; de gudomliga tvillingarna; bronsålder; järnålder; Skandinavien; kosmologi;

    Sammanfattning : This essay examines the Proto-Indo-European motif of the Divine Twins, as it has been interpreted in Scandinavia during the Bronze and Iron Ages. Because of the difference in opinion between archaeological researchers regarding when the Divine Twins disappeared, an examination of the material culture that has been connected to this motif is undertaken.

  5. 4. 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

  7. 5. 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.
