Over the past few years two of the largest and highest fidelity experiments conceived have been approved for construction: Euclid is an ESA M-Class mission that will map three-quarters of the extra galactic sky with Hubble Space Telescope resolution optical and NIR imaging, and NIR spectroscopy, its scientific aims (amongst others) are to create a map of the dark Universe and to determine the nature of dark energy. The Square Kilometre Array (SKA) has similar scientific aims (and others) using…

Cosmology with the Square Kilometre Array by SKA-Japan

In the past several decades, the standard cosmological model has been established and its parameters have been measured to a high precision, while there are still many fundamental questions in

Measuring baryon acoustic oscillations with future SKA surveys

The imprint of baryon acoustic oscillations (BAO) in large-scale structure can be used as a standard ruler for mapping out the cosmic expansion history, and hence for testing cosmological models. In

Radio selection of the most distant galaxy clusters

We show that the most distant X-ray detected cluster known to date, ClJ1001 at z=2.506, hosts a strong overdensity of radio sources. Six of them are individually detected (within 10") in deep 0.75"

Dark matter and dark energy interactions: theoretical challenges, cosmological implications and observational signatures

TLDR
The motivations underlying the need to introduce dark matter and dark energy interaction, its influence on the background dynamics and how it modifies the evolution of linear perturbations are reviewed.

Galaxy Alignments: Observations and Impact on Cosmology

Galaxy shapes are not randomly oriented, rather they are statistically aligned in a way that can depend on formation environment, history and galaxy type. Studying the alignment of galaxies can

Perturbations in Lemaitre-Tolman-Bondi and Assisted Coupled Quintessence Cosmologies

In this thesis we present research into linear perturbations in Lemaitre-Tolman-Bondi (LTB) and Assisted Coupled Quintessence (ACQ) Cosmologies. First we give a brief overview of the standard model

Proximal Splitting Methods in Signal Processing

TLDR
The basic properties of proximity operators which are relevant to signal processing and optimization methods based on these operators are reviewed and proximal splitting methods are shown to capture and extend several well-known algorithms in a unifying framework.

Fast Directional Continuous Spherical Wavelet Transform Algorithms

TLDR
The construction of a spherical wavelet analysis through the inverse stereographic projection of the Euclidean planar wavelet framework is described, which provides a savings of O(radicNpix) over a direct quadrature implementation for Npix pixels on the sphere.
