1. Fitting a photospheric prompt emission model to GRB data: The Kompaneets RMS approximation (KRA)
University essay from KTH/FysikAbstract : 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. READ MORE

2. Single-peaked gamma-ray bursts in the Fermi GBM catalogue
University essay from KTH/FysikAbstract : 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. READ MORE

3. Prompt emission in Gamma-ray bursts; Photospheric Radiation from Synchrotron-Like spectra
University essay from KTH/FysikAbstract : 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. READ MORE

4. High-Redshift Gamma-ray Bursts as seen by SVOM/ECLAIRs
University essay from Luleå tekniska universitet/RymdteknikAbstract : 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. READ MORE

5. Exploring Absorption in the Host Galaxies of Gamma-Ray Bursts
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : Gamma-ray bursts (GRB) are extremely high energy pulses that are connected to supernovae and black hole formation. They are divided into two forms, long and short GRBs. READ MORE
