Dwarf Galaxies in a Cosmological Context: A Testbench for Galaxy Modeling
… are to investigate the roles of reionization and supernova feedback in determining the star-formation histories of low-mass dwarf galaxies and to explore the effect of differing numerical implementations of supernova feedback on galactic enrichment and winds. Our models include a wide range of …

Towards AMR Simulations of Galaxy Formation
… the work in chapter 8 by implementing a kinetic supernova feedback mechanism in FLASH and contrasting it with the results from the GADGET-2 code. I find that AMR codes dissipate energy much more efficiently than in SPH codes.

Cosmological Simulations with Resolved Supermassive Black Hole Binary Dynamics and Accretion
… of the size-mass relation. However, the supernova feedback in the simulation is found to be too inefficient, particularly in low-mass galaxies, resulting in excessive star formation and, consequently, over-massive galaxies and SMBHs. This work also presents the first implementation of a …

Galaxy Formation in the Lambda-Cold Dark Matter Cosmology
… mass function (IMF) in starbursts and superwind feedback, and Bower et al (2006), which incorporates AGN feedback with a standard IMF. I compare the luminosity function, colours, sizes and morphology distributions of present-day galaxies in the models and with the SDSS. The Bower et al model …

Modelling star formation and stellar feedback in numerical simulations of galaxy formation
… the gas through ionizing radiation, winds and supernova (SN) explosions. Given the highly non-linear nature of the problem, numerical simulations provide an invaluable tool with which to study galaxy formation. Yet, even with contemporary computational resources, the inherently large dynamical …

Cosmological Simulations of Galactic Disc Assembly
… than is observed. This problem is alleviated by supernova feedback. We found that by increasing the feedback in the simulations, we decrease the amount of stars that are accreted onto the main galaxy. The star formation is quenched more efficiently in low mass satellites when stronger feedback is …
