Einstein-Aether Cosmological Scalar Field Models
The so-called Einstein-Aether theory is General Relativity coupled (at second derivative order) to a dynamical time-like unit vector field (the "Aether"). It is a Lorentz-violating theory and has gained much attention in ... -
A SCUBA-2 survey of high-redshift galaxy protoclusters & The calibration of the JCMT Transient regions
Part 1) The brightest high-redshift sub-millimetre galaxies (SMGs) represent the rarest and most extreme star-forming events in the Universe and are thought to be the progenitors to some of the most massive local galaxies. ... -
Spherically Symmetric Einstein-Aether Kantowski-Sachs Cosmological Models with Scalar Field
In this thesis we first give a brief introduction to the application of dynamical systems to cosmology. This enables us to study spherically-symmetric cosmological models in Einstein-aether theory with a scalar field. ... -
Volume-Preserving Coordinate Gauges in Linear Perturbation Theory
(2013-02-27)The main goal of this thesis is to present cosmological perturbation theory (based on the standard Friedmann cosmological model) in volume-preserving coordinates, which then provides a suitable basis for studies in ...
