Penetration of supernova radioactivities in the solar system
… a supernova blast and the solar wind, using the FLASH code. We find that the supernova ejecta can penetrate the solar system within the orbit of the Earth if the supernova explosion is within 10pe of the Sun. Since 10 pc marks the nominal ""kill radius"" within which biosphere damage is severe …

The Influence of Physical Processes in Galaxy Clusters on Observable Cluster Scaling Relations
… plus hydrodynamic simulation produced using the FLASH code, we study the impact of cluster structure and dynamical state on the distribution of scatter in the X-ray temperature and Sunyaev-Zel’dovich (SZ) scaling relations. We also examine possible systematic biases in cluster cosmology, such as …

Towards AMR Simulations of Galaxy Formation
… 3 I outline the optimisations I make to the FLASH code to enable larger simulations to be run. These include developing and testing a new FFT gravity solver. With these complete, in chapter 4 I present results from a collaborative code comparison project in which we test a series of different …

Examining the growth and evolution of magnetic fields in clusters of galaxies: a numerical perspective
… large-scale cosmological simulations with the FLASH code combined with a simplified model of the acceleration of cosmic rays responsible for the generation of radio halos, we find that the galaxy cluster frequency distribution and expected number counts of radio halos from upcoming …

The fates of binary companions in Type Ia supernovae within the single-degenerate scenario
… adaptive mesh refinement simulations using the FLASH code. We consider several different companion types, including main-sequence-like stars, red giants, and helium stars. In addition, we include the symmetry-breaking effects of orbital motion, rotation of the non-degenerate star, and Roche-lobe …
