  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. Performance Evaluation of a 3D Printed Mirror Actuator : A Comparison with the James Webb Space Telescope

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Louise Leopoldsson; Ellen Lindsjö; [2023]
    Nyckelord :Actuator; James Webb Space Telescope;

    Sammanfattning : This study aims to investigate the similarities in precision and performance between a James WebbSpace Telescope mirror actuator, the part controlling the motion of the primary mirror segments,and two 3D printed replicas. The two replicas were made from the plastics PLA and PETGand based on the designs of Zachary Tong. LÄS MER

  4. 3. Starshades: Geoengineering Solutions and Technosignatures in Direct Imaging Phase Curves

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

    Författare :Claudia Skoglund; [2023]
    Nyckelord :Starshades; extraterrestrial intelligence; stellar evolution; technosignatures; phase curves; direct imaging; habitable zone.; Physics and Astronomy;

    Sammanfattning : The stellar luminosity increases as a star evolves which inevitably yields a higher temperature on planets in orbit around the star. It is reasonable to assume that intelligent civilizations would tackle this issue through installing artificial structures that can alter the radiation received by the planet. LÄS MER

  5. 4. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy

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

    Författare :Elias Önerud; [2023]
    Nyckelord :Cross-correlation; cross-correlation spectroscopy; cross-correlation analysis; super-Neptune; astronomy; astrophysics; WASP-107; WASP-107 b; CRIRES ; SysRem; exoplanet; transmission spectrum; transit;

    Sammanfattning : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. LÄS MER

  7. 5. 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
