  1. 6. Prompt emission in Gamma-ray bursts; Photospheric Radiation from Synchrotron-Like spectra

    Kandidat-uppsats, KTH/Fysik

    Författare :Erik Vitols; [2022]
    Nyckelord :Gamma-ray burst; radiation mechanisms: thermal and non-thermal;

    Sammanfattning : Gamma-ray bursts (GRBs) are the most luminous phenomena in the Universe, explosions whoseenergy is generated by supernovae or mergers of dense objects such as neutron stars. The GRBemission is divided into the prompt emission phase characterized by γ-ray radiation and the afterglowof lower energy radiation. LÄS MER

  3. 7. Gravitational Waves in Bimetric Gravity

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

    Författare :Erik Schildt; [2022]
    Nyckelord :;

    Sammanfattning : Understanding the cause of the accelerated expansion of the Universe is one of the most pressing issues in modern cosmology. An alternative to the LambdaCDM-model is bimetric gravity which is an extension of Einstein's theory of general relativity. LÄS MER

  4. 8. Self-consistent dielectric formalism scheme for the paramagnetic electron gas under warm dense matter conditions

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

    Författare :Fotios Kalkavouras; [2022]
    Nyckelord :Warm Dense Matter WDM ; Quantum One-Component plasmas qOCP ; Vashishta-Singwi VS ; Dielectric Formalism;

    Sammanfattning : The present thesis aims to further a somewhat unexplored area of Warm Dense Matter (WDM) physics through the use of tools developed within the dielectric formalism. WDM is an exotic form of matter with densities close to the solid state and temperatures of several eV. LÄS MER

  5. 9. Constraining the Neutron Star Equation of State

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

    Författare :Klara Olofsson; [2022]
    Nyckelord :neutron star; equation of state; dense matter;

    Sammanfattning : Neutron stars are stellar objects of extreme properties. The dense core enables usto study nuclear matter beyond saturation density. The exact composition of matterat such densities is not yet established, but the thermodynamic states of the matteris theoreticized by the Equation of State (EOS). LÄS MER

  7. 10. Escaping Compact Object Binaries from Globular Clusters

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Annie Csomor; [2022]
    Nyckelord :Compact object binaries; binary black holes; BH-NS binaries; escaping binaries; globular clusters; escaping compact object binaries from globular clusters; escaping compact binaries; Physics and Astronomy;

    Sammanfattning : Since 2015, the LIGO-Virgo-KAGRA scientific collaboration (LVK) has detected gravitational waves from more than 90 merging compact object binaries using ground-based interferometric detectors. Compact objects orbiting in binary systems emit gravitational waves leading to a loss of energy. LÄS MER
