Simulations of galaxies help researchers understand astronomical observations better. The EAGLE simulation, a large project in which Leiden astronomers play a leading role, shows the evolution of the Universe, from just after the Big Bang to the present day.

COVID-19 poses a significant barrier to intra-regional trade within the EAC, causing interminable hold-ups at the internal borders.

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

Within the bachelor's program of Education and Child Studies, we include the minor Kindermishandeling en Verwaarlozing: een levensloopperspectief and several other courses.

Pintores, arquitectos y exposiciones internacionales –como las de Barcelona y Sevilla– tuvieron un papel crucial en la definición y visualización del carácter idiosincrático de cada región.

Providing a valuable overview of regionalism throughout the entire continent, Regionalism in Modern Europe combines both geographical and thematic approaches to examine the origins and development of regional movements and identities in Europe from 1890 to the present.

A permanent exhibition on the place of humans in the cosmos. This is something Franx wants to use his Spinoza Prize for. ‘So much progress has been made that we are still trying to define the questions. In finding the answers we are constantly coming up against surprises.’

Latin America has seen multiple waves of regional integration, with various levels of success. The last wave foundered after the rise of nationalist politicians. But new developments require a reconsideration, including a number of new, more collaborative-minded presidents coming to power and urgent…

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…

The aim of this study was to provide insight into how teachers in higher education can be supported in the design, implementation and evaluation of group assignments by developing a theoretical and evidence-based framework for the design of group assignments.

On 19 April 2022, Armin Cuyvers and Frederik Behre gave an online guest lecture for students of Los Andes University in Bogotá covering the topics of comparative regional integration and specifically the EU experience.

On 1 April 2020, Ivan Romashchenko defended his thesis 'Related Party Transactions and Corporate Groups: When Eastern Europe Meets the West'. The doctoral research was supervised by Prof. S.M. Bartman en Prof. A. Radwan (Kaunas, Lithuania).

In this article, Tokdemir & Klein examine the strategic actions of governments against domestic terrorist groups and domestic terrorist groups’ reactions to such actions.

Why does one person radicalize to involvement in terrorist violence within a group-based context, while another engages in this form of violence alone?

These are the proposed research projects for LEAPS 2019. Please note that not all projects will go ahead and some may still be added in the near future. Final funding decisions lie with the Faculty sponsors. And please make a note that if you are interested in an ESA project, to check if your state…

Can SMILE, our multi-component intervention, which combines cognitive-behavioural therapy for insomnia, mindfulness, stress, and lifestyle components, improve sleep quality? Can it also improve mood and quality of life and prevent depression and anxiety in the long term?

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.

How does self-reliance lead to a decrease in collaboration for public goods?

Diplomatic services across the world are trying to keep up with the times. In Abu Dhabi Jan Melissen, Senior Fellow International Relations and Diplomacy at ISGA and the Clingendael Institute, experienced how non-Western spaces can be among the more stimulating ones for practitioners of diplomacy to…

Research at Leiden Observatory spans the full width of modern astrophysical enquiry. It is based on observation, theory, simulation, and experiment. Two broad clusters characterize the ongoing research. Within each theme, researchers carry out their personal and specialized research programme. The two…

Improvements of weak gravitational lensing shape measurements are presented and some used for data analysis.

This study seeks to partially fill the knowledge gap about national culture in Africa, basing its research on data on ethnolinguistic groups (instead of administrative regions).

This article discusses the impact of symbolic gender representation on the willingness of citizens to coproduce.

How did free agents cooperate with the VOC and the WIC, through lobbying for private interests within the Companies as well as at the highest political levels?

Astronomers want to understand the Universe, from the Big Bang to the present day, and what the future will hold. In Leiden they focus on two key questions: ‘How did stars and planets originate’ and ‘How were galaxies and black holes formed in the young Universe?’ A new generation of telescopes – just…

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.

How can we organize the food system in the Amsterdam Metropolitan Region in a more sustainable and democratic way? Prof. Cristina Grasseni gave a presentation of her work at the Food Council Metropolitan Region Amsterdam.

During an Erasmus+ research stay in Rwanda, Frederik Behre gave several guest lectures to bachelor's and master's students enrolled in the various law programmes of the University of Rwanda.
