Ruimtetelescoop Euclid is in staat om de geheimen van het heelal te ontrafelen. Dat laten de afbeeldingen zien die ESA vandaag heeft gepubliceerd, volgens de astronomen die met de data van de telescoop werken. De beelden overtreffen alle verwachtingen. De wetenschappers binnen het Euclid-consortium,…

Bedreigde talen kunnen voortleven als ze goed worden geleerd aan nieuwe sprekers, zoals mensen met een migratieachtergrond. Dit stelt bijzonder hoogleraar Felix Ameka in zijn oratie op 30 september. Nederlanders kunnen daaraan bijdragen door zich minder ‘beleefd’ op te stellen richting mensen van wie…

In this thesis, we study systems of electrons in which strong correlations give rise to emergent exotic physics.

In the first part, we introduce a new condition, called toric-additivity, on a family of abelian varieties degenerating to a semi-abelian scheme over a normal crossing divisor.

In this thesis, we present new laboratory data of interstellar dust analogues.

This thesis consists of two main parts. The first part (Chapters 2 and 3) deals with a class of Markov process called Quasi-Skipfree (QSF) processes.

A modern ship design process is subject to a wide variety of constraints such as safety constraints, regulations, and physical constraints.

This thesis focus on the interaction between M dwarf stellar winds and Galactic cosmic rays and the possible effects on the habitability of exoplanets.

Understanding interactions in quantum many-body systems remains one of the most profound and difficult challenges in condensed matter physics.

This dissertation combines the use of defined microenvironments, high-resolution fluorescence microscopy, and time-resolved analysis, to study intracellular and cellular motility.

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.

This thesis studies the geometry of representation varieties and character stacks. These are spaces parametrizing the representations of a finitely generated group, typically the fundamental group of a compact manifold, into an algebraic group G.

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

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.

This thesis investigates how quantum, quantum-inspired, and hybrid quantum-classical computation can enhance key points of the automated machine learning (AutoML) pipeline under the constraints of noisy intermediate-scale quantum (NISQ) devices.

In this thesis it is posed that the central object of preference discovery is a co-creative process in which the Other can be represented by a machine. It explores efficient methods to enhance introverted intuition using extraverted intuition's communication lines.

The mycorrhizal symbiosis is among the most widespread species interactions on Earth⁠. This thesis focuses on orchid mycorrhiza, a unique mycorrhizal type that has caught scientists’ attention for centuries⁠.

De Universiteit Leiden is een internationaal georiënteerde en brede universiteit. We onderscheiden vijf wetenschapsdomeinen waarbinnen ons onderzoek en onderwijs plaatsvindt.

On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.

This dissertation, Layered Loyalties: The Natuurkundige Commissie in the Netherlands Indies (1820-1850), studies the Natuurkundige Commissie.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

Elk academisch jaar verzorgt het Natuurwetenschappelijk Gezelschap Leiden (NGL) vijf hoogstaande wetenschappelijke lezingen en een excursie.

This thesis explores how bees and hoverflies are distributed across the Dutch landscape and how ecological and landscape factors shape their occurrence.

This collection of papers was compiled in celebration of the remarkable academic career of Professor Wil Roebroeks, who has established himself as one of Europe’s leading figures in Palaeolithic archaeology over the past three decades and founded the Human origins research group at Leiden University…
