ESA’s Gaia mission has produced the richest star catalogue to date, including high-precision measurements of nearly 1.7 billion stars and revealing previously unseen details of our home Galaxy.

The unit residue group, to which the present thesis is devoted, is defined using the norm-residue symbol, which Hilbert introduced into algebraic number theory in 1897.

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 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,…

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

Since it was announced that North Korean President Kim Jong-un is ready to launch an intercontinental nuclear missile, fear of a nuclear war is growing by the day. Professor and North Korea expert Remco Breuker talks about the increased international tensions and their consequences for his work.

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.

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.

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.

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…

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.

The Faculty of Humanities has two advisory groups for Diversty & Inclusion: one for staff members and one for students.

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,…

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.

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.

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…

Together with researchers from over the world, the ENIGMA-Anxiety Working Group endeavors to unravel the neurobiology of anxiety disorders and related constructs.

In my research, we developed a method to distinguish knots. A knot is a mathematical depiction of the everyday knot that occurs in ropes and cords.

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.
