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.

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.
-
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.
-
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.

understand the excess baryonic mass in the centres of high-mass, early-type galaxies
This thesis aims to enhance our understanding of galaxies by testing theoretical models of galaxy formation against observations, particularly in the cases of extreme systems which have been found to have an excess of baryonic mass in their central regions, in the form of either supermassive black holes…

Galaxies and the structures in which they are embedded
Wetenschappers bij de Leidse Sterrewacht onderzoeken de fundamenteel natuurkundige verschijnselen die voor structuur in het heelal zorgen. Deze processen brengen materie bijeen tot sterrenstelsels en gas bijeen tot sterren. Met behulp van krachtige telescopen en geavanceerde berekeningen en computersimulaties…

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.

De zoektocht door het heelal
Astronomen willen het heelal begrijpen, van de Oerknal tot nu, en hoe dit verder zal gaan. In Leiden concentreren ze zich daarbij op twee vragen: 'Hoe ontstaan sterren en planeten? en 'Hoe ontstonden in het jonge heelal sterrenstelsels en zwarte gaten?' Een nieuwe generatie telescopen – net klaar of…

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?
-
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.
