• #### Tests of the Planck Cosmology at High and Low Redshifts ﻿

(2019-04-27)
The inflationary ΛCDM cosmology currently provides an accurate description of the Universe. It has been tested using several observational techniques over a wide redshift range, and it provides a good fit to most of them. ...
• #### The Host Galaxies of Luminous Reddened Quasars at z~2 ﻿

(2018-10-20)
The work in this thesis concerns the host galaxies of a class of luminous, yet heavily-obscured, quasars at z$\sim$2 - a peak epoch of both star formation and black hole accretion. Here, we seek to characterise the ...
• #### EXOCOMETS AT LARGE ORBITAL RADII AND THEIR INWARD TRANSPORT IN DEBRIS DISCS ﻿

(2018-10-20)
Planetary systems are not only composed of planets, but also of km-sized rocky and icy bodies that are confined within belts similar to the Asteroid and Kuiper belt in the Solar System. Mutual collisions within these belts ...
• #### Fast Stars in the Milky Way ﻿

(2018-10-20)
I present a comprehensive investigation of fast stars in the Milky Way, from brisk disc stars to stars escaping the Galaxy. My thesis is that fast stars are the smoking guns of extreme stellar collisions and explosions, ...
