From atoms to the cosmos: exploring the cosmic web beyond collisional ionisation equilibrium
Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

Smoothly breaking unitarity : studying spontaneous collapse using two entangled, tuneable, coherent amplifiers
The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

Multiple star formation: chemistry, physics and coevality
Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

Ingredients of the planet-formation puzzle
High-angular-resolution observations of the circumstellar material have uncovered numerous and very diverse substructures in protoplanetary discs, raising the question of whether they are caused by forming planets or other mechanisms.

Algorithm design for mixed-integer black-box optimization problems with uncertainty
The increasing competition in the automotive industry requires the tailored, swift development of technologically sophisticated vehicles. Therefore, the computationally expensive state-of-the-art simulation technologies are combined with optimization algorithms. An example of a real-world optimization…

Quantitative pharmacology of antimicrobials
Antimicrobial drugs constitute a fundamental part of modern medicine. The global rise in antimicrobial resistance poses a major threat to global health.

Understanding protein complex formation: The role of charge distribution in the encounter complex
Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

Predicting the future: Predictive control for astronomical adaptive optics
The field of exoplanet research is rapidly advancing through the development of new technology, observing techniques, and post-processing methods.

Tuning in to star-planet interactions at radio wavelengths
Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

Hydrodynamics and the quantum butterfly effect in Black Holes and large N quantum field theories
Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

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.

X-raying extragalactic gas: warm-hot gas in the EAGLE simulations
I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

Ruthenium- and cobalt-based artificial metalloenzymes for photocatalytic water oxidation in artificial photosynthesis
Producing green energy has become the main goal in our society in the search of reducing or eliminating the carbon emission from fossil fuels.

Unlocking Cosmic Depth and Detail
This thesis utilises the exceptional sensitivity and resolution of LOFAR to explore the low-frequency Universe, while simultaneously advancing the telescope's capabilities to enable new scientific discovery.

Leidse archeologen identificeren schedel van sabeltandtijger
Leidse archeologen hebben een aantal botfragmenten geïdentificeerd, die twee jaar geleden in Duitsland zijn opgegraven: ze zijn afkomstig van een sabeltandtijger. Het bleken delen van de schedel van de prehistorische katachtige te zijn, van meer dan 300.000 jaar oud.

Evolutie van bacteriële beweging ontrafeld
Een internationaal team met onderzoekers uit Leiden heeft ontdekt hoe een bacterie een intern systeem heeft herschikt om grip op beweging te krijgen. Gecontroleerde beweging is heel belangrijk bij het binnendringen van een gastheer, met mogelijk ziekte tot gevolg. Publicatie op 27 april in Nature Co…

Digits & Deviations of Dynamical Systems
Dynamical systems describe the evolution of objects in a space over time and may be used to model physical phenomena. Due to this, much research is dedicated to understanding the mathematics of dynamical systems.

Surveying young stars with Gaia: Orion and the Solar neighbourhood
OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.

Mining the kinematics of discs to hunt for planets in formation
Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…
