1. Petrography of impactites from the Dellen impact structure, Sweden
University essay from Lunds universitet/Geologiska institutionenAbstract : Identification and characterization of shock-metamorphic features in hypervelocity impact craters is important for our understanding of how shock waves interact with geologic materials and how impact craters form, which in turn is essential to our understanding of what role impact cratering played in the development of our solar system. Of particular interest are accessory minerals like apatite, which contains various volatiles that can affect the atmosphere of a body, or magnetite whose magnetic properties constitute a remote sensing indicator which allows us to study and understand the internal structures of distant bodies.

2. Atmospheric Gravity Waves revisited with the EISCAT radar
University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen; Uppsala universitet/Institutionen för fysik och astronomiAbstract : It is known that AGWs strongly interact with Traveling Ionospheric Disturbancescalled TIDs (e.g. Kirchengast et al., 1996). READ MORE

3. NH Planetary-Scale Circulation in Troposphere and Stratosphere: A Spectral and Dynamical Perspective
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : Dynamic Systems Theory (DST) and spectral analysis are employed to study the tropospheric jet stream and the stratospheric polar vortex. The objective is to investigate the relationship between Rossby wave activity and inverse persistence and dimensionality of geopotential height at 250 hPa and 10 hPa, as these two dynamical indicators are expected to show a characteristic behavior of Rossby wave harmonics.

4. Numerical solutions to the Boussinesq equation and the Korteweg-de Vries equation
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : The aim of the report is to numerically construct solutions to two analytically solvable non-linear differential equations: the Korteweg–De Vries equation and the Boussinesq equation. To accomplish this, a range of numerical methods where implemented, including Galerkin methods. READ MORE

5. Superradiant axion clouds and their interaction with astrophysical plasma
University essay from KTH/FysikAbstract : Axions are one of the best-motivated particles beyond the standard model of particle physics and a promising candidate for dark matter. Through the superradiant instability, axions can extract a significant amount of rotational energy from spinning black holes resulting in dense axion clouds. READ MORE
