  • Microbiology and the limits to life in deep salts 

    Payler, Samuel Joseph (The University of Edinburgh, 2018-07-02)
    Deep subsurface evaporites are common terrestrial deep subsurface environments found globally. These deposits are known to host communities of halophilic organisms, some of which have been suggested to be millions of ...
  • Ultra-red galaxies 

    Lewis, Alexander John Robert (The University of Edinburgh, 2018-11-29)
    Dusty star-forming galaxies (DSFGs) are highly luminous (LFIR ≳ 10¹² L⊙), very distant (z ≳ 2.5) and ≳ 10× rarer then ‘normal’, NIR-selected (BzK), star-forming galaxies. Capable of producing a Mstars ≳ 10¹¹-M⊙ galaxy after ...
  • Applications of branching processes to cancer evolution and initiation 

    Nicholson, Michael David (The University of Edinburgh, 2018-11-29)
    There is a growing appreciation for the insight mathematical models can yield on biological systems. In particular, due to the challenges inherent in experimental observation of disease progression, models describing the ...
  • Spectroscopic monitoring of long-term AGN transients: threading the micro-needle 

    Bruce, Alastair Graham (The University of Edinburgh, 2018-07-02)
    All active galactic nuclei (AGN) are known to vary in the rest-frame UV/optical. Typical variations are on the order of 30% or so and are stochastic in nature. Therefore, the discovery of a number of extreme AGN transients, ...
  • First investigation of electromagnetic coupling of the d*(2380) hexaquark 

    Kay, Stephen John Donald (The University of Edinburgh, 2018-11-29)
    This thesis presents the first measurement of the d*(2380) (hexaquark) electromagnetic coupling, extracted from the deuteron photodisintegration (~γd → d* →~np) reaction. The experiment was carried out at the Mainzer ...
  • Properties of the first galaxies 

    McLeod, Derek Johannes (The University of Edinburgh, 2017-07-10)
    With the Hubble Space Telescope and its near-infrared capabilities, it is now possible to probe deep into the epoch of reionization, improving our understanding of galaxy evolution through cosmic history. Whether it is ...
  • Neutron diffraction of hydrogen inclusion compounds under pressure 

    Donnelly, Mary-Ellen (The University of Edinburgh, 2017-07-10)
    When ice is compressed alongside a gas, crystalline 'host - guest' inclusion compounds known as gas clathrate hydrates form. These compounds are of interest not only for their environmental and possible technological ...
  • Theoretical considerations in the use of scalar-tensor theories of gravity in inflationary models 

    Edwards, David Craig (The University of Edinburgh, 2018-07-02)
    The inflationary paradigm is one which was designed to answer questions that arose from classical Hot Big Bang cosmology. The period of rapid expansion in the early Universe provides a mechanism to solve the flatness, ...
  • Role of active galactic nuclei in galaxy evolution 

    Nisbet, David Maltman (The University of Edinburgh, 2018-07-02)
    It is now believed that most, if not all, galaxies contain a supermassive black hole (SMBH) and that these play a crucial role in their host galaxies' evolution. Whilst accreting material, a SMBH (known as an active ...
  • First-principles studies of gas hydrates and clathrates under pressure 

    Teeratchanan, Pattanasak (The University of Edinburgh, 2018-11-29)
    Gas hydrates are molecular host-guest mixtures where guest gas species are encapsulated in host water networks. They play an important role in gas storage in aqueous environments at relatively low pressures, and their ...
  • Studies of dynamically and statically compressed antimony 

    Coleman, Amy Louise (The University of Edinburgh, 2018-07-02)
    Physics at extreme conditions is not a young field; there have been decades of developments that have allowed us to generate high-pressure and high-temperature conditions in a vast array of materials. Conventionally, ...
  • Simple molecular systems at extreme conditions 

    Turnbull, Robin William (The University of Edinburgh, 2018-07-02)
    This thesis project has focussed on the experimental study of simple molecular systems at extreme conditions. High-pressure and high-temperature techniques have been used in combination with Raman spectroscopy and X-ray ...
  • Ray-traced radiative transfer on massively threaded architectures 

    Thomson, Samuel Paul (The University of Edinburgh, 2018-07-02)
    In this thesis, I apply techniques from the field of computer graphics to ray tracing in astrophysical simulations, and introduce the grace software library. This is combined with an extant radiative transfer solver to ...
  • Mixtures of methane and water under extreme conditions 

    Pruteanu, Ciprian Gabriel (The University of Edinburgh, 2018-07-02)
    The hydrophobic effect has been a topic of research for decades, not only due to its importance as the primary building block of much of chemistry (it dictates which solvent can dissolve which solutes) and biology (guiding ...
  • Microswimming in complex fluids 

    Ives, Thomas Robert (The University of Edinburgh, 2018-07-02)
    Many microorganisms have the ability to propel themselves through their fluid environments by periodically actuating their body. The biological fluid environments surrounding these microswimmers are typically complex ...
  • Microbial responses to extreme radiation environments 

    Wadsworth, Jennifer Louise (The University of Edinburgh, 2018-07-02)
    Microorganisms are known to tolerate a variety of extreme environments, such as high and low pH, desiccation and a wide range of temperatures that would prove uninhabitable for most eukaryotic cells. However, extreme ...
  • Large scale simulations of genome organisation in living cells 

    Johnson, James (The University of Edinburgh, 2018-07-02)
    Within every human cell, approximately two meters of DNA must be compacted into a nucleus with a diameter of around ten micrometers. Alongside this daunting storage problem, the 3D organisation of the genome also helps ...
  • Mechanical properties of particle-stabilised liquid-liquid interfaces 

    Rumble, Katherine Ann (The University of Edinburgh, 2018-07-02)
    Over the past couple of decades interest in particle-stabilised emulsions or Pickering emulsions has greatly increased. When using particles as stabilisers, as opposed to surfactants, the interface becomes more rigid and ...
  • Applying high performance computing to profitability and solvency calculations for life assurance contracts 

    Tucker, Mark (The University of Edinburgh, 2018-07-02)
    Throughout Europe, the introduction of Solvency II is forcing companies in the life assurance and pensions provision markets to change how they estimate their liabilities. Historically, each solvency assessment required ...
  • Dynamics of numerical stochastic perturbation theory 

    Garofalo, Marco (The University of Edinburgh, 2018-07-02)
    Numerical Stochastic Perturbation theory is a powerful tool for estimating high-order perturbative expansions in lattice quantum field theory. The standard algorithm based on the Langevin equation, however, suffers from ...
