  1. 1. Core-collapse Supernovae Theory vs. Observations

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Dennis Alp; KTH.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astrophysics; Supernovae; Physics; Fysik;

    Sammanfattning : A core-collapse supernova (CCSN) is an astronomical explosion that indicates the death of a massive star. The iron core of the star collapses into either a neutron star or a black hole while the rest of the material is expelled at high velocities. LÄS MER

  2. 2. Late time emission from core-collapse supernovae

    Detta är en avhandling från Stockholm : Stockholm University

    Författare :Cecilia Kozma; Stockholms universitet.; [1996]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stjärnor;

    Sammanfattning : .... LÄS MER

  3. 3. Supernovae seen through gravitational telescopes

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Tanja Petrushevska; Stockholms universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; supernovae; strong gravitational lensing; star formation history; supernova rates; supernovor Gravitationslins; Physics; fysik;

    Sammanfattning : Galaxies, and clusters of galaxies, can act as gravitational lenses and magnify the light of objects behind them. The effect enables observations of very distant supernovae, that otherwise would be too faint to be detected by existing telescopes, and allows studies of the frequency and properties of these rare phenomena when the universe was young.

  4. 4. Observations of distant supernovae and cosmological implications

    Detta är en avhandling från Stockholm : Fysikum

    Författare :Rahman Amanullah; Stockholms universitet.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cosmological parameters; cosmology; astro physics; supernovae; type Ia supernova; NATURAL SCIENCES Physics Astronomy and astrophysics Cosmology; NATURVETENSKAP Fysik Astronomi och astrofysik Kosmologi;

    Sammanfattning : Type Ia supernovae can be used as distance indicators for probing the expansion history of the Universe. The method has proved to be an efficient tool in cosmology and played a decisive role in the discovery of a yet unknown energy form, dark energy, that drives the accelerated expansion of the Universe.

  5. 5. The Frequency of Supernovae in the Early Universe

    Detta är en avhandling från Stockholm : Department of Astronomy, Stockholm University

    Författare :Jens Melinder; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; supernovae; supernova typing; supernova rates; photometric redshifts; Lyman Break Galaxies; NATURAL SCIENCES Physics Astronomy and astrophysics Astronomy; NATURVETENSKAP Fysik Astronomi och astrofysik Astronomi; astronomi; Astronomy;

    Sammanfattning : Supernovae are cosmic explosions of cataclysmic proportion that signify the death of a star. While being interesting phenomena in their own right, their brightness also make them excellent probes of the early universe. Depending on the type of the progenitor star and the origin of the explosion different subjects can be investigated. LÄS MER
