Radio galaxies near the epoch of reionisation
This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

Some Assembly Required: The Structural Evolution and Mass Assembly of Galaxies at z
This thesis investigates the structural evolution and assembly of galaxies since the first few billions years after the big bang.

Astrophysical plasma modeling of the hot Universe: Advances and challenges in high-resolution X-ray spectroscopy
Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

Studying dark matter using weak gravitational lensing : from galaxies to the cosmic web
Of all the mass in our Universe, 80% is thought to consist of a hypothetical and invisible substance called dark matter (DM).

The galaxy–dark matter connection: a KiDS study
In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.
-
Faint Quasars at Very Low Frequencies
In this thesis, we use low-frequency and high-frequency radio observations to address the following questions regarding quasars: is the radio loud/quiet quasar dichotomy real?
-
The colours of the extreme universe
This thesis presents pioneering work on the panchromatic emission of some of the most luminous galaxies in the early Universe: star forming galaxies and active galactic nuclei.
