  1. 1. Simulation-based discrimination of Crab pulsar models with XL-Calibur

    Master-uppsats, KTH/Fysik

    Författare :Dennis Åkerström; [2024]
    Nyckelord :Astroparticle Physics; Astrophysics; Detector Physics; Simulation; Theoretical Physics; Engineering Physics; Pulsar models; Crab pulsar; Astropartikelfysik; Astropartikelfysik; Detektorfysik; Simulering; Teoretisk Fysik; Teknisk Fysik; Pulsar modeller; Krabbpulsaren;

    Sammanfattning : Polarisation of X-ray light is being investigated with polarimeters to extend the borders of what can be observed. Distant compact objects, such as pulsars, that are to small on the sky to be analysed with imaging can be investigated by analysing the polarisation of the emitted light. This can reveal physics previously hidden by their small nature. LÄS MER

  3. 2. James Webb Space Telescope Observations of Jupiter’s Moon Europa

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Aulon Nura; Isac Engblom; [2023]
    Nyckelord :;

    Sammanfattning : The creation of life has puzzled humanity since the dawn of time. With the launch of thecutting-edge James Webb Space Telescope (JWST) at last year's closing, the next step in humanity'ssearch for life has been taken. LÄS MER

  4. 3. Properties of the Optical Hot Spots in the Circumstellar Ring of SN 1987A

    Master-uppsats, KTH/Fysik

    Författare :Christos Tegkelidis; [2023]
    Nyckelord :;

    Sammanfattning : The proximity of Supernova 1987A provides a great opportunity to study the aftermath of the impact of the ejecta with the dense clumps (observed as ”hot spots”) located in the equatorial circumstellar ring. This thesis examines the properties of the clumps by using Hubble Space Telescope optical imaging taken with the F625W and F675W broad filters between 1994 and 2022. LÄS MER

  5. 4. Estimating stellar limb darkening using exoplanet transits

    Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Sora Ishida; [2023]
    Nyckelord :Limb-darkening; CHEOPS; Transit; Exoplanet; PYCHEOPS; Physics and Astronomy;

    Sammanfattning : The brightness of the stars is not uniform over the surface as it varies depending on the wavelength and the atmosphere that the light propagates. Limb darkening is an optical effect caused by a decrease in brightness of the star towards the edge. LÄS MER

  7. 5. Finding the Seeds of Supermassive Black Holes: The Direct Collapse Black Hole Scenario

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

    Författare :Weihui Li; [2023]
    Nyckelord :;

    Sammanfattning : The origin of supermassive black holes (SMBHs,∼ 10^9M⊙) in the first billion years of cosmic history remains a mystery. Direct Collapse Black Holes (DCBHs,∼ 10^4M⊙) are considered one of the most promising hypotheses for the progenitor of SMBHs, as they are believed to provide a favorable starting point as massive seeds for SMBH formation.
