Stellar radio beacons for Galactic astrometry
A century ago, it was unclear whether the stars in the sky were clustered in groups, or widely spread in the universe.

Exploring future multi-messenger Galactic astronomy
For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.

Focal-plane wavefront sensors for direct exoplanet imaging: Theory, simulations and on-sky demonstrations
One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

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.

Chemical functionalization of the graphene surface for electrical and electrochemical sensing application
Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

Arithmetic of affine del Pezzo surfaces
In this thesis integral points on affine del Pezzo surfaces are studied.
-
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 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 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.

From Star-formation to Recombination: Expanding our View of the Radio-Recombination-Line Universe
The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).
-
Towards an ab-axis giant proximity effect using ionic liquid gating
In this Thesis, novel charge induction mechanisms of ionic liquids are treated, tested and experimented on complex oxides, in particular cuprates.

Quantitative live cell imaging of glucocorticoid receptor dynamics in the nucleus
In this thesis, the focus lies on studying glucocorticoid receptor dynamics in living cells with the aim of understanding how this transcription factor finds its DNA target sites to regulate transcription.

Dynamics and radiation from tidal disruption events
When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

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).

X-ray spectroscopy of interstellar dust: from the laboratory to the Galaxy
In this thesis, we present new laboratory data of interstellar dust analogues.

Hierarchical Systems
The thesis addresses the long-term dynamical evolution of hierarchical multiple systems.

Distant star formation in the faint radio sky
One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

Tanja Masson-Zwaan: klimaatakkoord voor de ruimte niet realistisch
Bij een werkbezoek aan een bedrijf dat ruimtepuin opruimt, opperde de Britse prins Charles of een klimaatakkoord speciaal voor de ruimte een goed idee is. Daar zal het in elk geval niet van komen, zeggen experts onder wie Tanja Masson-Zwaan.

Jan Hendrik Oort: bescheiden sterrenkundige van wereldfaam
Hij ontdekte hoe je de draaiing en het middelpunt van ons Melkwegstelsel berekent, voorspelde waar kometen vandaan komen en legde de basis voor de Nederlandse radioastronomie: de Leidse hoogleraar Sterrenkunde Jan Hendrik Oort (1900–1992). Piet van der Kruit, zelf ooit promovendus bij Oort, schreef…
