Since the Middle Passage is in the North Atlantic, and the North Atlantic has a relationship with the arctic, what relationship does the Arctic have with the Middle Passage? How can this relationship be used to provide a space of healing by uncovering Afro/diasporic counter narratives?

Area studies is an approach to knowledge that starts from the study of places in the human world from antiquity to the present, through the relevant source languages, with central regard for issues of positionality.

In this article, Makszin developed a conceptual framework for the operating mission of an independent Central Bank and traced changes in the operating mission of the Hungarian National Bank over its recent 27-year history together with Sebők and Simons. This study aims to understand the dynamics of…

The need for novel drugs as well as innovations in their development and application is as urgent as ever. Below we present our vision , mission, and our key research areas.

Today’s performances of medieval polyphony have a lot in common with those of other ‘classical’ or ‘early’ music. Ensembles perform pieces written by known or lesser known composers, which the listener can revisit by listening to recordings or reading a score.

The Graduate School of Social and Behavioural Sciences aims to provide a stimulating environment for conducting PhD research at an internationally competitive level within one of the excellent research programmes offered by its institutes.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

This is a Special Issue of the peer-reviewed journal 'Social Sciences and Missions', which provides a forum for exploration of the social and political influence of Christian missions worldwide.

How are top-down directives translated and implemented at mission level in UN peacekeeping?

Across Europe, the need for a more dynamic governance and a better societal integration of research and innovation is increasingly appreciated. Internal drivers of change (such as the digitalization of science) and political will to better align with societal needs and concerns are bringing about aspirational…

Optimally solving real-world expensive Black-Box Optimization (BBO) problems w.r.t. real-world constraints, such as wall-clock time and computational costs, is extremely difficult and tedious.

Our mission: a positive impact. Our vision: community. By involving the world around us in our education and research we make a positive impact. We do this by applying Open Science.

The Event Horizon Telescope (EHT) collaboration receives the 2021 Royal Astronomical Society Group Achievement Award. In April 2019, the EHT team presented the first-ever photograph of the shadow of a black hole. Leiden professor Huib-Jan van de Langevelde has been director of EHT since last year. Three…

In this book Adam Fairclough chronicles the odyssey of black teachers in the South from emancipation in 1865 to integration one hundred years later.

This book explores the intellectual and cultural flows between Asia and Europe which occurred during – and were formative of – the political and social changes of the first half of the twentieth century.

Would you like to do something for the victims of the war in Ukraine? Several actions have been set up to help the people in Ukraine. Read below what you can do.

The physical origin of the dozens of stellar-mass binaries, the mergers of which have been detected by the LIGO-Virgo-KAGRA collaboration via gravitational waves, is still unknown.

Optimization tasks in practice have multifaceted challenges as they are often black box, subject to multiple equality and inequality constraints and expensive to evaluate.

In White Lies and Black Markets, Fatah-Black offers a new account of the colonization of Suriname—one of the major European plantation colonies on the Guiana Coast—in the period between 1650-1800.

How did nineteenth century scholars evaluate each other and each other’s work through more or less informal practices of peer review?

This anthology contributes to a historically grounded understanding of the complex relationship between Christian missions and the roots of humanitarianism and its contemporary uses in a Middle Eastern context.

Certain cichlid fish in Lake Victoria seem to have adapted super-fast to changing circumstances. Dr Frans Witte from the Integrative Zoology section has been awarded an NWO subsidy (approx. € 240,000) to carry out PhD research into the rapid changes apparent in this fish species.

Continuous optimization is never easy: the exact solution is always a luxury demand and the theory of it is not always analytical and elegant.

Physicists understand little about quantum matter, which is a building block of future quantum computers. Theorists have now discovered that black holes with ‘dreadlocks’ harbor a similarly exotic order pattern, which makes calculations on quantum matter easier. Publication in Physical Review Letter…

This book is the first systematic analysis of the changes in the use of goods and services by households of Black South Africans since the early nineteenth century.

What is dark matter? How do supermassive black holes form? ‘Primordial’ black holes might hold the answer to these long-standing questions. Leiden and Chinese cosmologists have identified a new way in which these hypothetical objects could be produced just after the Big Bang. Publication in Physical…

Pulsars were first discovered in 1967 and since then the population has grown and expanded over several wavelengths.

The Dutch Black Holes Consortium receives 4.9 million euros from NWO for unravelling the mysteries of black holes and other mysteries of the universe. The Astronomy and Society group at Leiden Observatory is affiliated to use the leading research to introduce people of all ages and background, and children…

Electrons that spin synchronously around their axis, turn out to stay superconducting across large distances within magnetic chromium dioxide. Electric current from these electrons can flip small magnets, and its superconducting version could form the basis for a hard drive without energy loss. Publication…

The Court of Justice of the European Union has rocked European relations within the world of sport. In its long-awaited ruling, the Court found that UEFA ‘abused its dominant position’ by imposing sanctions on the twelve clubs that founded the Super League – an elite football competition – back in 2…

On December 13th & 14th Singer Niels Berentsen will defend his thesis Discantare super planum cantum. New Approaches to Polyphonic Improvisation 1300-1470 to obtain his doctoral degree.

The aim of the project is to contribute to the process of archive formation ongoing in Post-Apartheid South Africa through the inclusion of photographs that have been either unacknowledged or excised from the national canon.

On 3 December the Europa Institute organised a debate about the figure of Black Pete. The central theme of the debate was the role which the law can play in deciding the future of Black Pete.

An international team of astronomers has published a map of the sky showing over 25,000 supermassive black holes. The map, to be published in the journal Astronomy & Astrophysics, is the most detailed celestial map in the field of so-called low radio frequencies. The astronomers, including Leiden astronomers,…

Meet the newest Full Professor at the Leiden Observatory: Joe Hennawi. All the way from Santa Barbara, California, Hennawi will strengthen the astronomy institute. In Leiden, he will use his recent ERC Advanced Grant to study how supermassive black holes come into existence.

All kinds of reasons have been put forward for why plants apparently fail to make maximum use of the available light. None of these reasons can explain why after two billion years of evolution they are not black, like industrial photovoltaic solar cells. Are we missing something?

The New Scientist magazine has selected two young Leiden scientists for its Top 25 Young Talents in the Netherlands and Flanders: historian Karwan Fatah-Black and neuropsychologist Mariska Kret. Who will be the winner? You can vote for one of them!

Older children more frequently link Black Pete with a black person. Both younger and older children think positively about him. This is the conclusion of a study conducted by Judi Mesman, Professor of Diversity in Parenting and Development.

Finally we know for sure that there is a black hole at the centre of our own galaxy. Today, astronomers unveiled the first ever photo of Sagittarius A*, a super-massive object at the centre of the Milky Way. This picture could only be taken thanks to the cooperation of telescopes worldwide.
