The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

The group Theoretical Physics of Life Processes, led by Helmut Schiessel, focuses on the physics of chromatin, the DNA-protein complex that fills the nuclei of eukaryotic cells.

In a modernist interpretation of migration controls, nation states play a major role. This book challenges this interpretation by showing that comprehensive migration checks and permanent border controls appeared much earlier, in early modern dynastic states and empires, and predated nation states by…

In this thesis, I studied the origin and evolution of the non-thermal radiation in merging galaxy clusters.

Climate finance, especially for developing countries, is crucial for limiting global warming to 1.5C. However, the current level of North -South climate finance is chronically inadequate. As the climate crisis intensifies, more actors are entering the climate finance market, transforming the global…

This book discusses theories of crisis management and the radical right, to shed light on how responses to crisis influence radical right parties in their presence, discourse, and evolution. The book offers a comparative perspective by examining case studies with various traditions of radical right…

We are a community of researchers from diverse backgrounds who explore becoming and being human, in relation to the world around us and other living beings.

The largest genus within the Phyllanthaceae family is a group called Phyllanthus L. Recent studies have shown, that Phyllanthus is paraphyletic with the genera Glochidion, Breynia and Synostemon nested within it.

The research project of Jos Raaijmakers is nominated for the Huibregtsenprijs 2022. The researcher of NIOO, with a guest appointment at the Institute of Biology Leiden (IBL), is one of six nominees. On the Evening of Science & Society (Dutch: Avond van Wetenschap & Maatschappij), 10 October 2022, the…

Dr Amanda Henry has secured a prestigious Vici grant for her groundbreaking research project, Hominin FoodWays: Changing Diet and Food Processing Across Climate Frontiers. This five-year study, set to begin in September, aims to unravel the dietary adaptations of Eurasian hominins between 1.8 and 0.9…

Eleven researchers of the Faculty of Science are on the 2021 Highly Cited Researchers list of Clarivate Analytics. Only 0.1 per cent of researchers are included in this list, literally making them one in a thousand.

If we want to build robots and computer systems that are not only smarter but also possess more social skills, we first need to find out more about how humans interpret information. Max van Duijn and Tessa Verhoef conduct research at the intersection of cognitive science and AI.

A neural network mimics how our brain works. Evolutionary algorithms use the principle of natural selection to solve complex problems. This kind of 'natural computing' is being used to improve the diagnosis of Parkinson's disease or the production of steel.

Leiden Observatory is the astronomical institute of the Faculty of Science of Leiden University.

Research at the Catalysis and Surface Chemistry group is comprised of the following research themes:

Key publications of the Quantitative Pharmacology group

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,…

PBDL favors multidisciplinary research. Depending on the problems under investigation, PBDL establishes collaborations between experts from for example molecular genetics, molecular and electro cell physiology, biochemistry, organic chemistry, analytical mathematics, mathematical statistics and computational…

This handbook provides a resource for those already familiar with some kinds of micro-particles who wish to learn more about others, or for those just starting out in the study of microremains who wish to have a broad understanding about microscopic archaeology.

The aim of this research is to investigate the informative potential of drawings and decorations in Italian secular cantata manuscripts from the seventeenth century.

We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

The Van Vollenhoven Institute for Law, Governance and Society (VVI) is part of the Leiden Law School.

The field of exoplanet research is rapidly advancing through the development of new technology, observing techniques, and post-processing methods.

This research delves into a region of space known as the interstellar medium (ISM), which is essentially the area between the stars filled with gas and dust.

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.

On May 2nd, Petr Kocharov succesfully defended his doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Petr on this great result.

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.

Stellar feedback is a crucial ingredient in the evolution of galaxies.

The Role and Effectiveness of the G20. In this article, published in The Changing Global Order part of the United Nations University Series on Regionalism book series, author Jaroslaw Kantorowicz discusses the evolution of the G20.

How do Humanitarian Response Organizations (HROs) and Virtual & Technical Communities (V&TCs) collaboratively govern disaster sensemaking processes, and what challenges shape the effectiveness of these collaborations between 2010 and 2016?
