Thesis
Green, L. (2019). Dynamics of outflows driven by winds from supermassive black holes. (Thesis). Keele University. Retrieved from https://keele-repository.worktribe.com/output/415217

Feedback is a key element of galaxy evolution, and the accretion of gas onto a central supermassive black hole (SMBH) is an important source of feedback. Modelling the energy released as an optically thick wind (with speed vw) allows observable relat... Read More about Dynamics of outflows driven by winds from supermassive black holes.

X-ray spectral variability of disk winds in a sample of local active galactic nuclei (2019)
Thesis

In this thesis I will present the culmination of my research into the phenomenon of AGN winds using several X-ray telescopes (Suzaku, XMM-Newton and NuSTAR); I will do this primarily through the use of radiative transfer models (Sim et al. 2010). I w... Read More about X-ray spectral variability of disk winds in a sample of local active galactic nuclei.

Nanostructured materials as catalysts for the production of green fuels and platform chemicals (2019)

A carbon deposition and sulphur poisoning study of new pyrochlore catalysts for methane reforming (2019)
Thesis
Alfatlawi, Z. K. (2019). A carbon deposition and sulphur poisoning study of new pyrochlore catalysts for methane reforming. (Thesis). Keele University. Retrieved from https://keele-repository.worktribe.com/output/413837

Reforming of landfill gases for the production of syngas that leads to the generation of heat or electricity is a very promising pathway considering the increasing price of oil. The dry reforming technique is a very interesting approach to reduce the... Read More about A carbon deposition and sulphur poisoning study of new pyrochlore catalysts for methane reforming.

Detection and characterisation of stellar companions to transiting extrasolar planets through high resolution imaging (2019)
Thesis
Evans, D. F. (2019). Detection and characterisation of stellar companions to transiting extrasolar planets through high resolution imaging. (Thesis). Keele University. Retrieved from https://keele-repository.worktribe.com/output/413806

Since the discovery over two decades ago of the first `hot Jupiter', there has been persistent debate regarding the formation and origins of this class of planets. Some of the many `migration' theories for hot Jupiters suggest that these planets form...

The use of metabonomic profiling approaches for the investigation of complex food fraud (2019)
Thesis
Sidwick, K. L. (2019). The use of metabonomic profiling approaches for the investigation of complex food fraud. (Thesis). Keele University. Retrieved from https://keele-repository.worktribe.com/output/413093

Food fraud is a challenge in today's expanding global food industry. Recently weaknesses in current testing methods for meat authentication have been exposed. Labels are assumed to accurately describe the contents of meat products, however these can... Read More about The use of metabonomic profiling approaches for the investigation of complex food fraud.

Follow-up observations and characterisation of transiting hot Jupiter exoplanets (2019)
Thesis
Clark, B. J. M. (2019). Follow-up observations and characterisation of transiting hot Jupiter exoplanets. (Thesis). Keele University. Retrieved from https://keele-repository.worktribe.com/output/413092

The discovery of the first hot Jupiter exoplanet more than twenty years ago raised many questions. Such large, hot planets were not predicted to exist so close to their host star. Since then, more than 125 hot Jupiters have been discovered (to date),... Read More about Follow-up observations and characterisation of transiting hot Jupiter exoplanets.

Fundamental properties of M-dwarfs in eclipsing binary star systems (2019)
Thesis
Gill, S. (2019). Fundamental properties of M-dwarfs in eclipsing binary star systems. (Thesis). Keele University. Retrieved from https://keele-repository.worktribe.com/output/413089

The absolute parameters of M-dwarfs in eclipsing binary systems provide important tests for evolutionary models. Those that have been measured reveal significant discrepancies with evolutionary models. There are two problems with M-dwarfs: 1. M-dwarf...
