Tracing the evolution of the molecular gas content in galaxies is critical for a complete understanding of galaxy formation and evolution, as it provides the direct fuel for star formation. Studies of high-redshift (z>1) molecular gas reservoirs, most commonly traced by carbon monoxide (CO), have seen…

The intracluster medium (ICM) is a hot, tenuous and X-ray emitting gas that pervades galaxy clusters.

The following people are part of the Steering Group for Academia in Motion.

Strategic direction of the GTGC initiative lies with a Steering Group, composed of seven members from four Leiden University faculties. Chaired by Leiden's Professor of Global Transformations and Governance Challenges, the Steering Group addresses questions such as overall vision, staffing, communications,…

An Active Galactic Nucleus (AGN) is a highly luminous region at the center of a galaxy, powered by the accretion into a supermassive black hole and emitting energy from radio waves to gamma rays, often outshining the host galaxy.

Simulations of galaxy formation provide much more information about galaxies than a telescope. Simulations have been improving significantly in recent years. Astronomer Evgenii Chaikin made such a significant contribution to this field that he graduated with honours on February 27th.

On 14 November, Ilya Kokorin defended the thesis 'Intra-group financing and enterprise group insolvency: problems, principles and solutions'. The doctoral research was supervised by Matthias Haentjens and Reinout Vriesendorp.

Religion and ethnicity are inextricably linked in discourse within and about Central Asia. One common narrative suggests that as a result of differences between historically sedentary and nomadic populations, ethnic Tajiks and Uzbeks are naturally more religious and more likely to radicalise than their…

Over a seven year period an international team of scientists has mapped more than a quarter of the northern sky using the Low Frequency Array (LOFAR), a pan-European radio telescope. From Leiden, Astronomer Timothy Shimwell and Huub Röttgering, among others, are involved. It reveals an astonishingly…

On 15 July 2019 Hans-Martien ten Napel started a new series on freedom of religion or belief for the London School of Economics research-led interdisciplinary Religion and Global Society Blog.

What’s the fate of our sun, when in 5 billion years from now our Milky Way will clash with the Andromeda Galaxy? Leiden astronomers have been working on calculations on this collision. They recently gave a visual sneak preview on a big tech conference.

Healthy University Leiden consists of a taskforce, focus group and seminars.

Several so-called Special Interest Groups are linked to DSRP. These groups focus on specialized topics and organize their own group meetings, talks etc. Contact the group leader if you are interested to join. It is possible to be a member of multiple groups.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Through the clever use of two types of telescopes, a team of researchers has produced stunning images of clusters of galaxies. This not only produces beautiful images, but also provides more information about the enormous amounts of energy released around supermassive black holes in clusters. The astronomers,…

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

The purpose of eLaw's Working Groups is to stimulate a productive working environment for cooperation within the Center for Law and Digital Technologies at Leiden University.

An international team of astronomers has published the most sensitive images of the Universe ever taken at low radio frequencies, using the International Low Frequency Array (LOFAR). ‘LOFAR is unique in its ability to make high-quality images of the sky at metre-wavelengths’, said Huub Röttgering, Leiden…

The research at The Metabolomics & Analytics Centre is centered around developing innovating analytical methods to enable metabolomics-driven systems biology in personalized health strategies.

The China Region Group develops and monitors Leiden University's cooperation with China. It is chaired by the Dean of the Faculty of Science, Prof. Jasper Knoester, and consists of representatives of Leiden University's faculties and various policy departments.

The Royal Academy of Art and the Royal Conservatoire together with the Academy of Creative and Performing Arts (ACPA) at Leiden University are developing a new platform for research in and with the arts, with an emphasis on collaboration.

The LOFAR e-infrastructure group is responsible for deploying and maintaining LOFAR processing on distributed e-infrastructure. A co-operation between SURFsara, Leiden University and ASTRON, the group develops software to integrate the LOFAR stack with processing pipelines. Our software can schedule…

Three major cosmology-focused missions are planned for the next decade: the Euclid space telescope, the Vera C. Rubin Observatory in Chile, and the Nancy Grace Roman Space Telescope.

Every PhD candidate has access to MS Teams ‘LACDR PhD group’. This site is specially for PhD candidates of LACDR. We strive to collect here all relevant PhD information and to stimulate the collaboration and communication in the LACDR PhD community.

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?

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.

The extensive use of electronic communication channels and other devices has opened new possibilities for collecting data on human behavior. This information is sometimes openly accessible, but largely part of administrative registration systems that are not open to the broader public. The data provides…
