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. An Infrared Stellar Thermometer: Exploiting IGRINS Spectra
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : Using the infrared (IR) spectral range when measuring stellar spectra is beneficial compared to using the optical range mainly when observing distant stars through the dust dense interstellar regions in the Galactic mid-plane. Methods to determine stellar parameters from IR spectra are, however, not fully developed yet because technological difficulties in creating reliable IR detectors have slowed the advance of such methods.

3. Analysing the Effect of Working Memory Training on Brain Networks Using MEG and Neuroimaging
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Introduction: The brain can change its structure and functionality as a result ofexternal factors. The working memory (WM) of the brain is where informationcan be held and manipulated during a short period of time, with the purpose ofachieving higher cognitive functions such as reasoning and learning.

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. Gamma-ray emission study and multi-wavelength modeling of the FSRQ 3C 454.3
University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Abstract : This thesis treats the findings and current theories of the active galactic nuclei 3454.3. It mainly aims to describe the behavior of the specific source in the gamma-ray energy band as recorded by the Fermi-LAT satellite. Using NASA’s computational tools and all recorded data the variability of the source was assessed. READ MORE
