Point Process Modelling of Objects in the Star Formation Complexes of the M33 Galaxy
In this thesis, Gibbs point process (GPP) models are constructed to study the spatial distribution of objects in the star formation complexes of the M33 galaxy. The GPP models circumvent the limitations of the two-point correlation function employed in the current astronomy literature by naturally …

Stellar phase-space clustering in dwarf spheroidal galaxies
… we look at clustering of stars in phase-space in two dwarf spheroidal galaxies: Fornax and Sculptor. We use a novel measurement based on the particle phase space density, P2SAD, as a 2D extension of the two point correlation function, averaged with a number count within a volume in phase-space. …

The Two Point Correlation Structure of a Cylinder Wake
… study the complete four dimensional space time correlation function was measured in the wake of an untripped circular cylinder at a Reynolds number of 60 000. This correlation serves as the complete inflow boundary condition for an open rotor ingesting inhomogeneous turbulence. An important …

Galaxy evolution, cosmology and HPC : clustering studies applied to astronomy
… be used in other fields for data mining. The Two-point Correlation Function (TPCF), in particular, is used to characterize the distribution of matter and objects such as galaxies in the Universe. However, it's computational time will be restrictively slow given the significant increase in the …

Monte Carlo and Series Expansion Studies of the Anisotropic Driven Ising Lattice Gas Phase Diagram
… diagram can be predicted by investigating the two-point correlation function to first order in a high temperature series expansion. However, the series expansion fails to predict even qualitatively the α-dependence of the critical temperature.

The fractional quantum Hall regime in graphene
… smaller than one. Then, by the application of two mapping rules, one is able to obtain these properties for fractional quantum Hall states at arbitrary fillings, by conceiving the quantum Hall ferromagnets as vacua on which correlated electrons or correlated holes are added. The predicted …

Metallicity correlations in galaxies
… both the local and high-redshift Universe. The two-point correlation function is a useful tool for extracting information from the 2D metallicity maps that integral field spectroscopy produces. Using the current integrated field unit observations and simulations, this thesis tries to gradually …

Structure Function Relation of Porous 2D Material via SGCMC Simulation and Statistical Models
… impact, we need to make the structure function relation of concrete more accurate, accessible, and cost-effective. First, we formulate and implement the Semi-Grand Canonical Monte Carlo (SGCMC) simulation for fracture mechanics, which is a stochastic method that is capable of capturing …

Dust-Obscured Galaxy Protocluster and Cluster Survey (DOGPACS): Identifying Large-Scale Structures 9−10 Billion Light-Years Away
… Deep Wide-Field Survey (SDWFS) in Bootes. A two-point correlation function analysis demonstrates that the sample has a mass scale of the galaxy clusters. Using a more multi-wavelength SDWFS catalog, this study has also uncovered a proto-supercluster structure at z = 1.75 (10 billion …

Prediction of Trailing Edge Noise from Two-Point Velocity Correlations
… a turbulent channel flow by Moser et al. (1998). Two-point velocity and vorticity statistics of this data set were obtained by averaging 41 instantaneous fields. For comparisons purposes, experimental boundary layer data by Adrian et al. (2000) was chosen. Statistical reduction of 50 velocity …

Testing General Relativity with the next generation of cosmological surveys
… In general relativity (GR) framework view point, there are two ways to explain where this acceleration might originate from; this riddle might either emerge from some unknown dark energy models or general relativity is a mistake on cosmological scale and dark energy is insubstantial. …
