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.

The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…

Self-assembly is an abundant process in nature and is vital to many processes in living organisms.

The field of exoplanet research is rapidly advancing through the development of new technology, observing techniques, and post-processing methods.

Electron microscopy has become an extremely important techniquein a wide variety of elds.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

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.

How do you engage society to stop biodiversity loss? How do you create political and social involvement to deal with climate change? And how do you balance the economic needs of industry with the negative effects of pollution? If you find these kinds of questions interesting, then this Pre-University…

Quantum computing is an emerging technology, which holds the potential to simulate complex quantum systems beyond the reach of classical numerical methods.Despite recent formidable advancements in quantum hardware, constructing a quantum computer capable of performing useful calculations remains challenging.In…

In this Ph.D. thesis we study the interaction of low energy electrons with thin materials, namely layered materials (graphene, hexagonal boron nitride, molybdenum disulfide) and organic films. At these low energies the quantum mechanical wavelength of the electron wave function is in the order of a…

Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

Kunnen we van quantum-verrassingen quantum toepassingen maken? Kunnen we het leven onderzoeken en opbouwen vanuit de nano-schaal?

This multidisciplinary minor provides students with knowledge on how and why humans became the way they are. The minor focuses on the evolution of the species Homo sapiens from other hominin lineages and animal ancestors, and on the various factors shaping this process. Not only is human evolution of…

How were the Russians, under early modern conditions, able to incorporate this distant, undeveloped and, because frequent nomadic attacks, dangerous territory? And what role did the Kolyvan-Voskresensk plants play in this process?

This project uses archaeological, literary and epigraphic evidence to investigate urban development in Roman-period North Africa, compiling this in a GIS-linked database in order to analyse the development of urban settlement spatially over time.
