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…

Some 5000 years ago the people of the corded ware culture exchanged ideas about death on a continental scale. There were strong gender differences in these ideas: men were buried in an international style, and women in a local style. This discovery was made by archaeologist Quentin Bourgeois.

Two radio telescopes in Green Bank, West Virginia have brought together a few remarkable people. A new photo exhibition in the Old Observatory visitor centre gives an insight into the remote community. Due to the corona crisis, the Observatory is not open to the public. That’s why we’ve selected a few…

Minister Judith Uitermark proposes that 125 seats will become electable through provincial electoral lists and only 25 seats through a national electoral list, according to Dutch RTL news. Wim Voermans, Professor of Constitutional Law, comments on the plan.

Dr. Ahmad Al-Jallad and Prof.dr. Peter Akkermans have been awarded with the NWO Free Competition Grant for their research project 'Landscapes of Survival: Pastoralist Societies, Rock Art and Literacy in Jordan's Black Desert, c. 1000 BC to 500 AD'. Together, they study settlements, burials and inscr…

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…

In this book, a new generation of scholars offers fresh perspectives on the history of the Dutch slave trade. Traditionally, Dutch research has focused on business practices, often overlooking the enslaved and the complexities of illegal trade and violence.

The Leiden University Centre for Linguistics has been badly affected by the corona crisis: the research in the four labs and the fieldwork has come to a standstill. What are the implications?

Below, you can find the answers to frequently asked questions about the Summer School.

The following lectures/courses are given in the framework of the EU Jean Monnet Chair EUTAXGOV at Leiden University. Topic of this Jean Monnet Chair: EU Tax Governance and International Tax Law Making by the EU.

Adoptees in the Netherlands generally do not use more medication than their non-adopted peers.

The main interest of this project concerns learners’ perceived learning outcomes in massive open online courses and the factors related to their perceived learning outcomes.

Knowledge is everywhere at Leiden University. It is also accessible for those who do not study or work at the University.

Roll your sustainable sleeves! Our students and staff have found various ways to do just that, both at home and at our university.

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 LOFAR radio telescope produces petabytes of data every year. Radio Astronomers use complex multi-step pipelines to process this data and produce scientific images.

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.
