The next generation of high-contrast imaging instruments on space-based observatories requires sophisticated wavefront sensing and control in addition to a high-performance coronagraph.

Material Culture Studies revolves around the analysis of the cultural biographies of all sorts of material objects from flint axes, to pottery, to houses and monumental structures.

My work is motivated by the necessity to extend Standard Model of Particle Physics in order to explain three observed phenomena that this great theory fails to accommodate

Today, everybody and everything produces data. People produce large amounts of data in social networks and in commercial transactions. Medical, corporate, and government databases continue to grow. Sensors continue to get cheaper and are increasingly connected, creating an Internet of Things, and generating…

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

A plasma is an ionized gas with very low electrical resistivity. As such, magnetic field lines are 'frozen in' and move with the fluid. Magnetic field lines that are linked, knotted and tangled, cannot be undone by the fluid motions.

‘My name is Liz van der Kamp, and I am doing a Master’s in Astronomy and Cosmology. This Master’s is followed by the double bachelor in Astronomy and Physics, that I finished last year. For my bachelor research project I investigated transits of companion around a primary star that are asymmetric in…

The IBL represents the core of modern biological research at Leiden and we interact closely with the other life science Partner Institutes in the faculty:

We aim to keep animal testing to a minimum. We therefore assess for every study whether full account has been taken of the 3 Rs: replace, reduce, refine. The Animal Welfare Body advises researchers on this. We train our staff and provide further courses, which means we are able to continue to refine…

Researchers at Leiden Observatory study the fundamental physics that creates structure in the Universe. These processes collect matter into galaxies and gas into stars. With the use of powerful telescopes and advanced calculations and computer simulations, Leiden astronomers seek to understand the origin,…

Optimality in plant properties and processing.

The Metabolomics Facility of the University of Leiden has brought together two research groups from the Faculty of Science that are well-known for their expertise in two different fields: the Biomedical Metabolomics Facility Leiden, experts in clinical metabolomics and the Natural Products Laboratory,…

This study aims to make a practical contribution to a new understanding and use of 3D reconstructions, namely as ‘laboratories’ to test hypotheses and visualize, evaluate and discuss alternative interpretations.

Digital Archaeology is concerned with digital data for for archaeological research, and the computational methods and tools required to collect, analyse and manage it.

Links to various Digital Humanities organizations and resources, mainly in English.

The Faculty of Archaeology ranks as the best on continental Europe and is in the top ten of the world. Our master’s degree in archaeology offers the most diverse programme of its type in the Netherlands.

The thesis addresses the long-term dynamical evolution of hierarchical multiple systems.

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.

The Astronomy and Data Science master’s specialisation at Leiden University combines advanced Astronomy courses with relevant courses from the Computer Science programme at Leiden University.

Former PhD student Cameron Mackie will been awarded not one, but two dissertation prizes for his thesis on the aromatic universe. His work could provide us with a virtual sniff of space. ‘These molecules in space likely smell like a big charcoal grill!’

An international team of astronomers has shown in a laboratory at Leiden University (the Netherlands) that methane can form on icy dust particles in space. The possibility had existed for quite some time, but because the conditions in space were difficult to simulate, it was not possible to prove this…

The oldest university in the Netherlands was founded on 8 February 1575 in the Pieterskerk in Leiden. This was at the time of the Eighty Years’ War with the uprising of the northern provinces against domination by the Spanish.
