Studies of b Hadron decays to Charmonium, the LHCb upgrade and operation
(The University of Edinburgh, 2022-04-11)Precise measurements of CP violation provide stringent tests of the Standard Model towards the search for signs of new physics. Using LHC proton-proton collision data, collected by the LHCb detector during 2015 and 2016 ... -
Studies of phase and strength in high pressure vanadium
(The University of Edinburgh, 2022-04-04)High temperature and pressure states of matter are ubiquitous in nature. It is therefore of the upmost importance that they are understood. Extreme pressures can be obtained using both static and dynamic compression. ... -
Simulating the X-ray emission of hot gas in groups and clusters
(The University of Edinburgh, 2022-03-31)As some of the largest gravitationally bound objects in the Universe, galaxy groups and clusters provide a unique laboratory for testing models of cosmology and galaxy evolution. While many of the basic properties of ... -
Modelling extraterrestrial habitability, biomass and biosignatures through the bioenergetic lens
(The University of Edinburgh, 2022-03-31)In order to survive, evolve and thrive, life requires a biologically useful supply of energy and nutrients. While there is evidence for both throughout the solar system and beyond, quantifying the energetic threshold at ... -
Molecular dynamics simulations on the principles governing chromosome organisation
(The University of Edinburgh, 2022-03-23)In eukaryotes, chromosomes reside in the crowded environment of the cell nucleus. Understanding the principles or mechanisms governing the three-dimensional (3D) folding of chromosomes and the role that this plays in genome ... -
Structural studies of the trivalent lanthanides at ultra-high pressures
(The University of Edinburgh, 2022-03-22)The lanthanide and actinide metals have complex electronic and magnetic behaviour at high pressures and low temperatures, respectively, owing to the f electrons buried within the atoms participating in the bonding of ... -
Modelling uncertainties for measurements of the H → γγ Channel with the ATLAS Detector at the LHC
(The University of Edinburgh, 2022-03-21)The Higgs boson to diphoton (H → γγ) branching ratio is only 0.227 %, but this final state has yielded some of the most precise measurements of the particle. As measurements of the Higgs boson become increasingly precise, ... -
Sampling statistical distributions in physics: a machine learning approach
(The University of Edinburgh, 2022-03-18)This thesis presents work which uses Machine Learning techniques in a variety of sampling situations which appear in physics. In the first Chapter some background on Machine Learning will be presented which will lay the ... -
Computational investigations of thermoelectric properties of lead telluride, magnesium silicide, and magnesium stannide under high pressure and anisotropic stress
(The University of Edinburgh, 2022-03-14)I present a comprehensive picture of the electrical transport properties for PbTe, Mg2Si, and Mg2Sn under high pressure and stress. The electronic band structure and thermoelectric properties of p- and n-doped lead ... -
Multiplicity properties and spectral classification of B-type stars
(The University of Edinburgh, 2022-03-14)Massive stars are usually called cosmic engines due to their well-known importance at different scales, from shaping their surroundings to even cosmological implications. Binarity is one of the main ingredients in the ... -
Role of AGN feedback in galaxy evolution
(The University of Edinburgh, 2021-11-25)Over the past two decades, detailed studies in the nearby Universe have shown that accreting supermassive black holes (SMBHs; or active galactic nuclei; AGN) can have a significant effect on their host galaxies, suppressing ... -
Geochemistry of Enceladus and implications for life detection
(The University of Edinburgh, 2021-11-25)Enceladus, a moon of Saturn, is one of the most promising candidates for the search for life beyond Earth. The Cassini-Huygens mission revealed that Enceladus has a thick crust composed of water ice. Beneath this crust ... -
Measurement of the 25Mg(d, p)26Mg reaction to constrain nucleosynthesis in novae and the weak s-process
(The University of Edinburgh, 2021-11-25)The 25Al(p, γ) 26Si reaction rate is one of the few outstanding uncertainties in modelling the contribution from novae to the galactic budget of the long-lived radioactive isotope 26Al. The rate is dominated by three ... -
Theory uncertainties in parton distribution functions
(The University of Edinburgh, 2021-11-17)We are now in the era of high precision particle physics, spurred on by a wealth of new data from the Large Hadron Collider (LHC). In order to match the precision set by modern experiments and test the limits of the ... -
Exact solutions to the long-time statistics of nonequilibrium processes
(The University of Edinburgh, 2021-11-27)Nonequilibrium statistical mechanics deals with noisy systems whose dynamics breaks time-reversal symmetry. Stochastic Markov processes form a mathematical framework for a unified theory of nonequilibrium phenomena, ... -
Searches for new physics using low energy electron recoils in the LUX and LZ experiments
(The University of Edinburgh, 2021-11-27)There is evidence, on a range of astrophysical and cosmological scales, that most of the matter in the universe is comprised of invisible dark matter. The particle nature of this dark matter is inconsistent with the Standard ...
