• Shaping Massive Galaxies: the structural evolution of galaxies across Research output

  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.

• A well-established harmony in chaos: from isolated galaxies to galaxy clusters Research output

  The origin and evolution of galaxies are closely linked to many different physical phenomena.

• When galaxy clusters collide: the impact of merger shocks on cluster gas and galaxy evolution Research output

  Promotor: Prof.dr. H.J.A. Rottgering, Co-promotor: David Sobral

• Resolving gas-phase metallicity in galaxies Research output

  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 Research output

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

• Early death of massive galaxies in the distant universe Research output

  Promotor: M. Franx, Co-Promotor: I.F. Labbé

• The connection between mass and light in galaxy clusters Research output

  Promotor: Koen Kuijken Co-promotor: Henk Hoekstra

• The characteristics of galaxies with powerful radio jets Research output

  Radio jets are important to the evoultion of galaxies. However, it is still not fully understood how a radio jet can be triggered.

• Identifying the origins of galaxy formation Research output

  This thesis investigates how galaxies form and what diversifies the evolutionary histories of galaxies.

• Radio galaxies near the epoch of reionisation Research output

  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.

• Unveiling the nature of giant radio galaxies Research output

  The thesis deals with the study of giant radio galaxies (GRGs), which are radio galaxies of megaparsec sizes.

• Star-Forming Galaxies at the Cosmic Dawn Research output

  Promotor: Prof.dr. M. Franx, Co-Promotor: Rychard Bouwens

• Metals in the diffuse gas around high-redshift galaxies Research output

  Promotores: Prof.dr. J. Schaye & Prof.dr. C. Steidel (California Institute of Technology)

• Neutral outflows in high-redshift dusty galaxies Research output

  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 Research output

  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 Research output

  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 Research output

  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.

• Galaxy alignments from multiple angles Research output

  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…

• Causing a stir: Radiative and mechanical feedback in starburst galaxies Research output

  Promotores: Prof.dr. F.P. Israel, Prof.dr. P.P. van der Werf

• Machine learning for radio galaxy morphology analysis Research output

  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 Research output

  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.

• The alignment of galaxies across all scales Research output

  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 Research output

  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.

• Withstanding the cold: energy feedback in simulations of galaxies that include a cold interstellar medium Research output

  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…

• Some Assembly Required: The Structural Evolution and Mass Assembly of Galaxies at z Research output

  This thesis investigates the structural evolution and assembly of galaxies since the first few billions years after the big bang.
