A remarkable population of short period transiting rocky exoplanets with equilibrium temperatures on the order of 2,000 K has recently been discovered.

In this thesis, bioorthogonal chemistry is combined with correlative light-electron microscopy to selectively label and study pathogenic intracellular bacteria within the host immune cell.

Large telescopes can look so deep into the Universe that they can also look back billions of years in time. From 2018, the successor of the Hubble Space Telescope, the James Webb Space Telescope, will be able to see the period just after the Big Bang, when the first stars and galaxies formed. Astronomers…

From black holes to artificial intelligence and from drug research to data science: welcome to the fascinating world of the Faculty of Science. Our researchers, students and guests regularly give public lectures about their work. You are welcome to attend.

Everything you need to know about the minor Cultural Memory of War and Conflict.

Welcome to the Graduate School of the Faculty of Humanities.

The chaotic years after the Civil War are often seen as a time of uniquely American idealism—a revolutionary attempt to rebuild the nation that paved the way for the civil rights movement of the twentieth century. But Adam Fairclough rejects this prevailing view, challenging prominent historians such…

In 'Dutch Atlantic Connections, 1680-1800', Gert Oostindie and Jessica V. Roitman, both of the Royal Netherlands Institute of Southeast Asian and Caribbean Studies (KITLV) and also affiliated with the History Institute of Leiden University, assemble an internationally acclaimed selection of authors,…

It is a common technique in global optimization with expensive black-box functions to learn a surrogate-model of the response function from past evaluations and use it to decide on the location of future evaluations.

Artificial intelligence algorithms govern in subtle, yet fundamental ways, the way we live and are transforming our societies. The promise of efficient, low‐cost or ‘neutral’ solutions harnessing the potential of big data has led public bodies to adopt algorithmic systems in the provision of public…

Freshwater and brackish water ecosystems are arguably the most vulnerable ecosystems on earth, due to concentrated human developments in and around them. The Pontocaspian (PC) region located at the border of Europe and Asia contains a variety of brackish water ecosystems and unique inhabitants, known…

A century ago, it was unclear whether the stars in the sky were clustered in groups, or widely spread in the universe.

Journal of the Royal Anthropological Institute published Annemarie Samuels' article on the 2004 tsunami in the Indian Ocean. It's a detailed ethnographic account of the experiences of three Indonesian survivors.

We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

Galaxies in the Universe are distributed along the intricate framework of the Cosmic Web. Groups and clusters of galaxies comprise the densest regions in this network, and therefore, are excellent cosmic laboratories to study different aspects of galaxy evolution in extreme environments.

This paper written by Alexandre Afonso, Assistant Professor and Researcher at Leiden University, argues that gender norms and the political strength of the left were important structuring factors regarding why European countries choose migrant labour to expand their labour force in the decades that…

Human civilization consumes a huge amount of fossil fuels, which has resulted in an atmospheric CO2 level which has not been higher in over 800 millennia.

Modern computer-aided simulation tools used by various industries produce gigabytes of data. But currently, they take days and even up to weeks of computation effort. To make the best use of all these data, the DAMIOSO project focuses on developing algorithms and tools for managing, mining, and optimizing…

The mission of Thamyris/Intersecting is to rigorously bring into encounter the crucial insights of black and ethnic studies, gender studies, and queer studies, and facilitate dialogue and confrontations between them.

Over the last three decades, the discovery of exoplanets has revealed the boundless variety of worlds beyond our own Solar System⁠. Majority of planetary systems contain short-period planets that are larger than Earth but smaller than Neptune⁠.

We are a dynamic research group at the Leiden Institute of Physics. Our aim is to explore and understand quantum materials, including strange metals, high-temperature superconductors, and quantum critical electron matter.
