  1. 11. 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

  2. 12. Energy simulations of apartment buildings using IDA ICE

    Master-uppsats, KTH/Hållbara byggnader

    Författare :Asim Mohammadusman Doddamani; [2023]
    Nyckelord :;

    Sammanfattning : This study presents an energy signature method for analyzing thermal inertia of apartment building located in Stockholm using IDA ICE software. The method involves analyzing the building’s consumption of energy hourly and calculating the temperature change rate of the building’s thermal mass. LÄS MER

  3. 13. Pulse Amplitude Reconstruction in the LDMX Hadronic Calorimeter Readout

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Aksel Draguanov Mihaylov; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The universe shows signs of containing some invisible matter, known as dark matter. There are many possible constituents for dark matter, one such being light dark matter which would interact with ordinary matter through a new mediator force and have masses in the range of a few MeV to GeV.

  4. 14. Defining dark jets at the particle level

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Gustav Lindberg; [2023]
    Nyckelord :Particle physics; Dark matter; QCD; Physics and Astronomy;

    Sammanfattning : One hypothesis that attempts to explain dark matter is dark QCD, which suggests that there would be a dark sector made up of dark quarks. Dark quarks would interact with each other through dark QCD similar to how Standard Model quarks interact with each other through Standard Model QCD. LÄS MER

  5. 15. Mono-X signal characterisation from two-component DarkMatter using Neural Networks

    Master-uppsats, Uppsala universitet/Högenergifysik

    Författare :Max Fusté Costa; [2023]
    Nyckelord :;

    Sammanfattning : In the recent decade, neural networks have become one of the leading tools in the search for the elusive nature of dark matter and its interactions through the analysis of numerically simulated data. This project introduces a minimal dark sector consisting of three additional fields and studies it through two mono-X signatures,mono-jet and mono-Z. LÄS MER
