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.
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).
Radio galaxies at low frequencies: high spatial and spectral resolution studies with LOFAR

Facets of radio-loud AGN evolution: a LOFAR surveys perspective
Promotor: H.J.A. Rottgering, Co-Promotor: R.J. van Weeren
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.
Weighing the Dark: Cosmological Applications of Gravitational Lensing
Promotor: K. Kuijken, Co-Promotor: H. Hoekstra
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.
The connection between mass and light in galaxy clusters
Promotor: Koen Kuijken Co-promotor: Henk Hoekstra
