Experimentalism has emerged as a prominent approach for addressing environmental problems. Christopher Ansell (Berkeley) and Martin Bartenberger (Leiden University) survey the diversity of experimentation methods, identifying their strengths and weaknesses, and suggesting possibilities for fruitfully…

How do we process language and speech? How do we integrate information at different levels – intonation, sentence structure, meaning, tone, words, sounds - and how does information at one level interact with information at another level?

The project’s main aim was to build a reconstruction of a prehistoric house plan, without using any metal tools. How effective are tools made of stone, flint, bone, antler and wood? What are the constraints imposed by the various building materials? How much labour do we need and how much knowledge…

We simulate interstellar clouds with special plasma expansions and chemical reactions on icy dust grains to be measured in ultra-high vacuum setups. This provides the data necessary to guide and interpret astronomical observations and to model reaction networks in space. [Harold Linnartz]

How do atoms and molecules end up forming planets? That's what astrochemist Julia Santos studied during her PhD. She discovered the dominant process behind the formation of methanol in space – a finding that surprised the entire field.

The research programme Formal Theoretical and Experimental Linguistics brings together LUCL researchers who focus mainly on formal theoretical and experimental linguistics.

Psycholinguistic research

It is an established fact that the Standard Model has to be extended to explain the so-called Beyond the Standard Model (BSM) phenomena: dark matter, matter-antimatter asymmetry of the Universe and neutrino flavour oscillations.

The experimental approach of science applied to artistic research

This thesis revolves around the electronic spectroscopy of molecules in the laboratory and the search for the carriers of the diffuse interstellar bands (DIBs).

This thesis is about the study of hydrocarbons via infrared spectroscopy.

In October 2014 a new publication on artistic research has been launched. The book is called Artistic Experimentation in Music. An Anthology, edited by Darla Crispin and Bob Gilmore, and published by Leuven University Press.

The Executive Board has appointed Professor Harold Linnartz as Professor of Laboratory Physics with effect from 1 June 2011. Linnartz has worked since 2005 as senior lecturer at the Leiden Observatory.

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

The zebrafish is a promising vertebrate model organism in early drug discovery and development.

This study examines the mutual intelligibility between all 225 pairs of 15 Chinese dialects, in two main branches, i.e., six Mandarin dialects and nine non-Mandarin (Southern) dialects.

Stars and planets form within cold, dense clouds of gas and dust drifting through interstellar space. Although dust makes up only a small fraction of this material, it plays a key role in shaping the chemical evolution of these environments.

This project employs a systematic experimental approach to examine the interaction of these two hitherto independent lines of research (tone sandhi and focus realization) in six dialects of Chinese, which lie on a continuum between dialects with dense tonal distributions and sparser distributions. In…

This dissertation aims at discussing the nature and the linguistic factors assumed responsible for speech intelligibility problems of Sudanese learners of English.

Lecture, LUCL Colloquium

In this research project, we aimed to obtain more insight in the role of mast cells in the immune driven disorders rheumatoid arthritis and atherosclerosis.

This thesis aims at contributing to our understanding of the semantic and prosodic properties of object foci in Greek, employing theoretical and experimental tools.

This dissertation provides an account of polar questions in Italian dialects from a typological, theoretical and empirical perspective.

This thesis investigates durational aspects of the Italian mobile diphthongs with respect to other rising diphthongs and monophthongs and it shows to what extent the monophthong/diphthong alternation still occurs in contemporary Italian.

Carbohydrates, or sugars, are the most diverse and most abundant biomolecules known. However, the isolation of carbohydrate samples in sufficient amounts and purity is often impractical or even impossible, so the chemical synthesis of glycosides becomes relevant. The glycosylation reaction, in which…

The research project of Yannis Patoukas proposes to explore the different intersections between experimental rock music of the 1960s and 1970s and electroacoustic music, with regard to studio practices and production techniques and their creative possibilities.

The 10th Experimental Archaeology Conference of EXARC took place in Leiden, Netherlands, over three days; 20th to the 22nd April 2017, in Leiden University’s Faculty of Archaeology. A conference report was published on the website of EXARC.

The Fritz Zwicky Prize 2022 for Astrophysics & Cosmology has been awarded to Prof. Ewine F. van Dishoeck for her pioneering, decades-long work in astrochemistry and molecular spectroscopy, as well as for her leadership within the astronomical community. The award was announced today by the European…

The Leiden Observatory has appointed a new professor. Selena Viti will hold a chair in Molecular Astrophysics. Viti will build a research group that combines different research techniques to unravel the secrets of local and external galaxies. ‘My main ambition is to change the way scientists interpret…

How are stars and planets formed? Is life outside Earth possible? These questions are being researched by Professor of Molecular Astrophysics Ewine van Dishoeck at Leiden University. Her pioneering work has earned her the Kavli prize in the category of astrophysics. The prize consists of 1,000,000 dollars…

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.

This thesis takes steps toward understanding the interaction between gas-phase and solid-state molecules in star- and planet-forming regions.

Matilda Siebrecht has found the perfect combination of her interests, namely experimental archaeology, and journalism. She was asked by EXARC, a foundation that aims at connecting experimental archaeology professionals, to host a monthly podcast on this topic. ‘It is called Finally Friday, airing every…

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…

The research article ‘Anatomy of a notch. An in-depth experimental investigation and interpretation of combat traces on Bronze Age swords’ is one of the most downloaded articles on the Journal of Archaeological Science website. This journal is one of the best for impact factor in the field. The article,…
