Shaping Massive Galaxies: the structural evolution of galaxies across
Galaxies in the local Universe fall into two main categories of spirals and ellipticals. In this Thesis, we explore the structural evolution of galaxies into this bimodal distribution.

Resolving gas-phase metallicity in galaxies
Galaxies are environments where gas coalesces, cools, and is converted into stars. However, it remains unclear the exact mechanisms through which galaxies acquire, redistribute and lose their gas.

Cold gas in distant galaxies
The formation and evolution of galaxies is fundamentally driven by the formation of new stars out of cold gas.

Neutral outflows in high-redshift dusty galaxies
Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

X-ray spectroscopy of merging galaxy clusters
This thesis focuses on the X-ray spectral analysis of merging galaxy clusters and the plasma code development for future high-resolution X-ray spectroscopy observations.
-
Galaxy formation traced by heavy element pollution
Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.
-
The interplay between stars, gas and dust in faint star-forming galaxies
When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

Dawn of the red and dead: stellar kinematics of massive quiescent galaxies out to z = 2
Promotores: Prof.dr. M. Franx, Prof.dr. M. Kriek (Univ. of California at Berkeley)
-
Galaxy alignments from multiple angles
Galaxies form and live inside dark matter haloes. As a consequence, they are exposed to the tidal fields generated by the surrounding matter distribution: this imprints a preferential direction to the galaxy shapes, which leads to a coherent alignment on physically close galaxies, called intrinsic a…

Machine learning for radio galaxy morphology analysis
We explored how to morphologically classify well-resolved jetted radio-loud active galactic nuclei (RLAGN) in the LOw Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) using machine learning.
-
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.

Political Religion Beyond Totalitarianism
The eleven innovative essays in this volume explore the notion that all forms of modern mass politics, including liberal democracies, need such a form of sacralization of politics to function.

Withstanding the cold: energy feedback in simulations of galaxies that include a cold interstellar medium
Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

The alignment of galaxies across all scales
Galaxy intrinsic alignments induce a major astrophysical contamination to weak gravitational lensing measurements and need to be modelled and mitigated when extracting cosmological information from such measurements.

Resolving the building blocks of galaxies in space and time
We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

Modern Perceptions of Ancient Religions
The aim of this Research Traineeship will be to analyze the underexplored reception of ancient religions in popular culture, taking Dutch spiritual magazines as a case study. There are five such magazines: Paravisie (1986- ), Paraview (1997- ), Happinez (2003- ), Bres (1965- ), and Prana/Mantra (1975-…

collisions: a study of particle acceleration and magnetic fields in merging galaxy clusters
On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.
