1. Fitting a photospheric prompt emission model to GRB data: The Kompaneets RMS approximation (KRA)
Master-uppsats, KTH/FysikSammanfattning : Gamma-ray bursts (GRBs) are some of the most energetic events in the universe. Shocks occurring below the photosphere are likely radiation mediated shocks (RMSs) and are suspected to shape the spectra. Due to computational costs of simulating RMSs, models had not been fitted to data and a faster model was needed. LÄS MER
2. Single-peaked gamma-ray bursts in the Fermi GBM catalogue
Master-uppsats, KTH/FysikSammanfattning : Gamma-ray burst light curves are notoriously irregular, yet a significant number consists of a single fast-rising, exponentially decaying pulse. These are called single-peaked light curves. LÄS MER
3. Prompt emission in Gamma-ray bursts; Photospheric Radiation from Synchrotron-Like spectra
Kandidat-uppsats, KTH/FysikSammanfattning : 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
4. High-Redshift Gamma-ray Bursts as seen by SVOM/ECLAIRs
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : Gamma Ray Burst (GRB) are very bright cosmological explosions signalling the catastrophic formation of a black hole. Therefore, they act like real light beacons that could be detected through-out the Universe and be used as probes to study the contents and phases of the early Universe. However, only a handful sample is known so far. LÄS MER
5. Investigating the Time Evolution of X-Ray Absorption in Gamma-Ray Bursts
Master-uppsats, KTH/FysikSammanfattning : .... LÄS MER
