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.

Carbonaceous asteroids preserve a record of early solar system processes, where minerals and organic molecules, like polycyclic aromatic hydrocarbons (PAHs), offer clues to planetary evolution and prebiotic chemistry.

This research delves into a region of space known as the interstellar medium (ISM), which is essentially the area between the stars filled with gas and dust.

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…

In this special edition of Information Polity there is a focus on the transparency challenges of using algorithms in government in decision-making procedures at the macro-, meso-, and micro-levels.

CONSENT (Consumer sentiment regarding privacy on user generated content services in the digital economy) is a research project funded by the European Union under the 7th Framework Programme. The question central to this research is whether recent changes to consumer and commercial practices developed…

Are there significant differences among the environmental impacts resulting form the production of Asian aquaculture commodities and what are the main causes for these?

What is movements and corridors of the Bornean pygmy elephant in Sebuku forest? What is the nature of human-elephant conflict in Nunukan District in time and space? What are the diets of the Bornean elephants related to crop raiding?

De politicologen Joop van Holsteyn en Tom Louwerse (Universiteit Leiden) zien dat referenda in Nederland de Euroscepsis een stem geven. Maar van een ‘Nexit’ is nog lang geen sprake.

Bij FAIR-ASSESS zijn onderzoekers betrokken van vijf verschillende Leidse faculteiten, en experts van buiten de universiteit. Het project is opgezet door Andrei Poama en wordt geleid door Josette Daemen.

Onze medewerkers en studenten maken deel uit van de taskforces van Una Europa. Deze taskforces vertalen de kernthema’s van Una Europa naar concrete acties.

Wetlands provide many ecosystem goods and services which include fish production. The sustainability of small-scale fisheries (SSF) has received considerable attention in recent years because fish is one of the major sources of animal protein to a considerable fraction of the global population which…

Het kabinet wees onlangs de gemeente Tubbergen aan voor de opvang van tweehonderd asielzoekers. Het leidde tot protesten van buurtbewoners. Voor EenVandaag duidt hoogleraar Marlou Schrover de situatie.

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.

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…

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

The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

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.

To study how planetary systems come into existence we study much younger systems still in formation.

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

The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.

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…

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?

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.

This dissertation presents the results of the importance of creativity for ICT-students of Dutch universities of applied sciences (in Dutch: hogescholen), and the functioning of training courses that aim to promote creative abilities is highlighted.

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

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.

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.

Microbial rhodopsins are photosensitive pigments implemented in the growth and adaptation of a large population of microorganisms.

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.

The Dutch atlas with pesticides concentrations in surface waters have been overhauled. This new, free accessible, website is in line with the European Framework Directive on Water (In Dutch: KRW).
