A new publication that brings together perspectives on language contact phenomena across temporal and spatial dimensions.

An archaeological case-study of the Pointe des Châteaux, La Désirade and Les Îles de la Petite Terre micro-region, Guadeloupe, F.W.I.

This PhD-research is conducted to test the hypothesis that Gutenberg and consorts developed a standardised and even unitised system for the production of textura type, and that this system was extrapolated for the production of roman type in Renaissance Italy.

Dark matter represents around eighty per cent of the total mass in the Universe. Yet, we still don't really know what it's made of. Astronomer Pavel Mancera Piña is looking for answers. With a Veni grant from NWO and the most advanced telescopes, such as the James Webb Space Telescope, he will investigate…

An international team of laboratory astrophysicists and astrochemical modellers has shown that glycine, the simplest amino acid and an important building block of life, can form under the harsh conditions that govern chemistry in space. The results have been published this week in Nature Astronomy and…

Astronomer Koen Kuijken and physicist Tjerk Oosterkamp have each been awarded a major subsidy by NWO. The funding will allow them to construct new research facilities.

A glittering visualisation of dark matter by Dutch artist Thijs Biersteker is on display in the Science Gallery at Trinity College Dublin. The installation – ‘Dark Distortions’ – was inspired by Euclid, a forthcoming ESA mission to study the mysterious nature of dark matter. Leiden astronomer Henk Hoekstra…

The modern-day Caribbean is a stunningly diverse but also intricately interconnected geo-cultural region, resulting partly from the islands’ shared colonial histories and an increasingly globalizing economy.

CERN has approved the construction and operation of SND@LHC, a neutrino detector at the Large Hadron Collider. It's a precursor for SHiP, a detector meant to detect dark matter. Leiden physicist Alexey Boyarsky is one of the initiators of both SHiP and SND@LHC.

Our annual "Science to Experience" exhibition of student works is hosted by the V2_ Lab for the Unstable Media. This year's theme is "PATTERN".

This thesis aims to demonstrate how the achromatic nature and design flexibility of liquid-crystal optics can be used to improve high-contrast imaging instruments to facilitate detailed exoplanet characterization.

A signal that is present both in the centre of our Milky Way and in distant places in the universe could reveal the origin of dark matter. This is what Leiden physicist Alexey Boyarsky concludes in an article in Physical Review Letters.

Spirits play a important role in post-colonial and minority literature as a means of processing black pages from history, according to literary scientist Chia-Sui Lee. PhD defence 11 January.

At the largest scales, two ingredients dictate the distribution of matter in the Universe. The first is dark matter, acting as an invisible scaffolding held together by gravitational forces.

The theoretical explanation of cosmic acceleration is nowadays one of the biggest puzzles in cosmology.

Researchers of the National University of Singapore and Leiden University have discovered that chimpanzees and bonobos share the contrasting colour pattern seen in human eyes, which makes it easy for them to detect the direction of someone’s gaze from a distance.

Tropical butterflies adapt to their environment to improve their chances of survival. The changes are triggered by hormone signals that transmit information about temperature to the butterflies' tissues. Biologist Ana Rita Mateus shows how a complex combination of environment, physiology and genetics…

The centre of our Galaxy is so dark and dense that it is almost impossible to observe what is inside. By catching the rare hypervelocity stars that are ejected from it, Elena Maria Rossi aims to unveil the mysterious environment around the supermassive black hole inside. But she’ll also be solving another…

The focus of the dissertation

We have studied shape with a particular focus on the zebrafish model system. The shape is an essential appearance of the phenotype of a biological specimen and it can be used to read out a current state or response or to study gene expression.

This thesis discusses the discovery potential of Intensity Frontier experiments.

In the first part of this thesis we study the geometry of folding patterns.

What does site patterning reveal about the social landscape dynamics across the historical divide?

The Computer Systems, Imagery & media (CSI) research programme performs research on methods and techniques for the design, implementation and application of advanced computer systems, in particular parallel, distributed and embedded computer systems.

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

The first direct detection of gravitational waves opened the possibility of mapping the Universe via this new and independent messenger.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

In this work, we attempt to answer the question:

How the global distribution of vegetation stands dominated by arbuscular and ectomycorrhizal plants relate to principle aspects of belowground carbon accumulation processes?

Wat gebeurt er op het schoolplein? Sensoren op kleding openbaren pijnlijke patronen

The majority of scientists, from archaeologists through to zoologists, collect huge volumes of data. Their massive databases contain large amounts of information which is difficult for humans to filter. With a solid grounding in statistics, we can develop algorithms for analysing and identifying patterns…

Are there acoustic cues for settlement stage larvae in deep-sea soundscapes around hydrothermal vents?

Every year, the Leiden Institute of Physics (LION) organises the Science Day. The goal is to highlight the newest research at LION, to socialise, and to welcome first year master students and new PhD candidates to our institute.

What are the 'dark' components of the universe?

After his PhD defense on 25 September Frits Veerman will go to the University of Oxford to do research at the Centre for Mathematical Biology.
