By a stroke of luck, a team led by Dutch PhD student Martijn Oei has discovered a radio galaxy of at least 16 million lightyears long. The pair of plasma plumes is the largest structure made by a galaxy known thus far. The finding disproves some long-kept hypotheses about the growth of radio galaxie…

The physics of black holes appears to be as far removed from the physics of electrons in metals as it can be.

Does the δ-machine have higher accuracy than the other feature-based classifiers in some conditions?

In this thesis, we have used numerical approaches to study the effects of translational symmetry breaking on strange metallic systems as realised by the holographic duality⁠.

The Leiden Slavery Studies Association (LSSA) is dedicated to promoting a greater understanding of slavery and post-slavery in any period and any geographical region.

There is no heritage without emotional sharing and clashing. This article explores the involvement of divergent emotions in heritage making by discussing the debate series of Imagine IC and the Reinwardt Academy and zooming in on the commemoration of slavery and imagery of ‘Black Pete’ in the Netherlands.…

For the first time, astronomers have observed in three dimensions that gas from spiral galaxies is blown upwards and downwards at high speed, far out of the galaxy. They thereby confirm the theory of galaxy evolution: that star-forming galaxies create intergalactic gas flows by discharging gas along…

The design for the METIS instrument for the Extremely Large Telescope (ELT) is final. The European Southern Observatory (ESO) has given the green light for production of all parts of the instrument. It is the first ELT instrument, designed and to be built under Dutch leadership, to formally pass the…

Adrian Hamers is researching the way in which celestial bodies orbit each other, now and in the future. This often turns out to be more erratic than you might think. He will defend his PhD dissertation on 21 June.

Over a seven year period an international team of scientists has mapped more than a quarter of the northern sky using the Low Frequency Array (LOFAR), a pan-European radio telescope. From Leiden, Astronomer Timothy Shimwell and Huub Röttgering, among others, are involved. It reveals an astonishingly…

Lecture, Research Seminar Europe 1000-1800

International organisations that represent collaborations between States are becoming increasingly more powerful, and they have an increasing impact on our daily lives. For example, the European Court of Human Rights in Strasburg established that minors have a right to legal aid immediately following…

This project applies a social-historical approach to examine and contrast various groups of African-American slave refugees who sought freedom within North America between 1800 and 1860. It innovatively distinguishes between different “spaces of freedom” for runaway slaves, namely sites of formal, semi-formal,…

The Netherlands is not particularly rich in ‘wild nature’. Comparatively, what we have is a lot of intensively used agricultural land. This means that from nature’s perspective there much to be gained by combining the ‘nature’ and ‘agriculture’ functions. Not an easy task in such a densely populated…

This project explored the role of material culture, in casu painted plaster and its technologies, in expressing dynamic social identities and in forging complex interwoven human relationships in the context of the Middle to Late Bronze Age of the Aegean and East Mediterranean.

Colonial and Global History combines a deep curiosity of transcultural processes such as imperialism, (de)colonization, and globalization with critical historical research on regional societies in Africa, Asia, and the Americas.

Thermodynamics is one of the founding scientific pillars that has helped us better understand heat engines, biology, ecosystems, and even black holes. While it fundamentally describes large systems by examining the bulk behavior of their constituents, it is anchored in the statistical equivalence of…

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

Considering the ways in which the ‘global turn’ is changing the theory and practice of historical disciplines, Explorations in History and Globalization engages with the concept and methodology of globalization, challenging traditional divisions of space and time to offer a range of perspectives on…

Leiden Center for the Study of Ancient Arabia

Although nanoparticles are extensively used in various applications like consumer products and have most probably entered the environment, little is known about the effects of these particles on living organisms.

LeiCenSAA is dedicated to the study of Ancient Arabia and the sharing of knowledge and expertise on this topic. Thefore it aims to collaborate closely with other research in the field.

Kaveh Lahabi's lab explores the exotic physics of quantum materials, whose underlying physics seems to have more in common with elementary particles and black holes, than ordinary metals and semiconductors.

If Dutch cinema is examined in academic studies, the focus is usually on pre-war films or on documentaries, but the post-war fiction film has been sporadically addressed.

This book provides an overview of critical scholarly reflections on the history of Dutch slavery and colonization, as well as how this translates into critical cultural practices.

This is the physics summer school of Leiden University. It is part of the Leiden Institute of Physics (LION). The summer school is intended for Bachelor (BSc) students in physics. It covers topics from quantum matter and optics, to biological & soft matter physics and cosmology and theoretical physics.…

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

The Jeugdwerkgroep is a national astronomy association for young people who are interested in astronomy. The Leiden section organizes a monthly meeting in the Old Observatory Leiden.

How safe do you feel walking on the street in Leiden? Do you feel safe, or are there situations that make you feel unsafe in the city? These are questions that city criminologist Marianne Franken of Leiden University wants to find answers to. In collaboration with the municipality of Leiden and the…

An international team of astronomers from Leiden Observatory and others, has for the first time mapped a piece of the dark, cosmic web. The research strengthens the hypothesis that the young universe consisted of huge numbers of small groups of newly formed stars. The astronomers publish their findings…

From fake news via WhatsApp to mini hearts from a 3D printer: four Leiden researchers have been awarded a Consolidator Grant by the European Research Council. These grants, of up to 2m euros, enable researchers to establish or expand their research team and continue to develop their career.

As Director-General of the ESO for the past ten years, Leiden University astronomer Tim de Zeeuw had ‘the best astronomy job in the world’. Back at the Leiden Observatory, he is focusing on the first 3D map of the Milky Way.

How do stars and galaxies form? What is dark matter? To answer these and other questions, we need increasingly large telescopes. And to build these, we need international partnerships. A series on the impact of collaboration.

Five projects with researchers from Leiden University have received a grant from the Dutch Research Council (NWO) to build or upgrade existing research facilities.
