Combining different disciplines, researchers work together to formulate innovative solutions to societal problems.

The supermassive black hole at the center of the Circinus galaxy is being fed with gas by two spiral arms. This is what PhD candidate Wout Goesaert discovered. But only a small percentage disappears into the black hole, the rest is ejected.

The field of science communication is very broad. Below is a list of organisations where SCS students can fulfill internships or where alumni have found jobs.

N. Karazin Kharkiv National University, The Main Astronomical Observatory,…

My work is motivated by the necessity to extend Standard Model of Particle Physics in order to explain three observed phenomena that this great theory fails to accommodate

The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.

One of the most important correlation functions in physics, especially in cosmology, is the energy density, which describes how much energy is present at each point in spacetime due to matter fields. A key contribution to the energy density of the primordial universe comes from gravitational waves (GWs),…

Internationalisation is an important part of the mission and vision of Leiden University. The Erasmus+ programme, an initiative of the European Commission, makes a substantial contribution to this goal. Erasmus+ provides grants for educational projects with partners within and outside Europe, and facilitates…

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

This thesis revolves around the electronic spectroscopy of molecules in the laboratory and the search for the carriers of the diffuse interstellar bands (DIBs).

On Saturday October 16, the special exhibition ‘Shared Sky: Canvases of the Universe’ opens in the Old Observatory in Leiden. The exhibit takes a cultural look at the starry sky by Aboriginal Australian and South African artists, and features colorful artwork that explores how these Indigenous cultures…

Radio telescope LOFAR maps the sky. It produces incredibly detailed images of the universe - and vast amounts of data. Huub Röttgering, director of the Leiden Observatory, talks about the challenges of working with those enormous datasets.

Leiden Professor of Astronomy Mike Garrett is searching for signs of extraterrestrial intelligence. In his Kaiser lecture on 23 April he will discuss how far science has progressed in this quest.

The Event Horizon Telescope (EHT) collaboration receives the 2021 Royal Astronomical Society Group Achievement Award. In April 2019, the EHT team presented the first-ever photograph of the shadow of a black hole. Leiden professor Huib-Jan van de Langevelde has been director of EHT since last year. Three…

Hoe kan de City Deal Kennis Maken bijdragen aan het formuleren van maatschappelijk relevant onderzoek dat de stad in al haar diversiteit centraal stelt? In de stad Leiden zijn burgers momenteel maar in beperkte mate betrokken bij het bepalen van de agenda van de lokale City Deal Kennis Maken. Dit onderzoeksproject…

In the master’s programme in Archaeology, you can follow courses on the archaeology of Europe, deepening your understanding of the continent’s long history.

Astronomers from Leiden Observatory have developed a new method to find distant quasars and better distinguish them from other objects that look like them, using machine learning techniques. The research result has been accepted for publication in the journal Astronomy & Astrophysics. It is the last…

This is an Erasmus+ International Credit Mobility project of Leiden University’s Faculty of Science with the Ethiopian Space Science and Technology Institute.

SuperCode: Sustainability PER AI-driven CO-DEsign

Astronomers from, among others, SRON and Leiden Observatory have discovered long-sought intergalactic gas with ESA’s space telescope XMM-Newton. This gas is one of the pieces of the puzzle to map the total amount of ‘normal’ matter in the universe. The research will be published in Nature on 21 June…

Making an impact by creating solutions for the challenges of the future. That’s what we do through our education and research in biodiversity and sustainability, artificial intelligence, complex networks, new medicines, quantum technology, and galaxies.

The thesis addresses the long-term dynamical evolution of hierarchical multiple systems.

To get an idea of the science communication products and research that is possible, a few examples of student projects of recent years are shown below.

We explore the particle physics and quantum world at the time of the big bang.

Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

Stars and planets form within cold, dense clouds of gas and dust drifting through interstellar space. Although dust makes up only a small fraction of this material, it plays a key role in shaping the chemical evolution of these environments.

Excavations at Geleen-Janskamerveld 1990/1991

This book explores the intellectual history of the Dutch empire from the sixteenth century to the postcolonial era, going beyond systemic thinkers to understand how empire was perceived in day-to-day life. It takes a transnational and transimperial approach to the Dutch empire, connecting European,…

On November 22nd, Morana Lukač succesfully defended her doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Morana on this great result.

European countries struggling how to deal with the issue of returning foreign fighters, women and children from the Caliphate.

For the first time, astronomers have managed to take a photo of a supermassive black hole and its shadow. They used the Event Horizon Telescope (EHT), a worldwide network of eight radio telescopes that together form a virtual telescope the size of the earth. The news was presented in six press conferences…

Henk Hoekstra and Alessandra Silvestri work on the astronomy and theoretical physics in the Euclid mission. These Dutch researchers are part of the mission.

De decentralisaties van de zorg aan langdurig zieken en ouderen, jeugdzorg, en werk en inkomen die vanaf 2015 zijn doorgevoerd in Nederland hebben geleid tot een transitie van een centraal naar een lokaal stelsel van zorg en welzijn. Deze transitie beoogt zorg en ondersteuning dichter bij de inwoners…

He discovered how to determine the rotation and centre of our Milky Way, predicted where comets come from and laid the groundwork for radio astronomy: Leiden Professor of Astronomy Jan Hendrik Oort (1900 – 1992). Piet van der Kruit, whose PhD supervisor was Oort himself, has written a biography about…

‘I got into Nature last year, I was nominated for a faculty teaching award and my kids don’t care. But if your simulations get on The Big Bang Theory then that’s something!’ says Huib van Langevelde.

For only the second time ever, astronomers have linked a neutrino to an object outside our Milky Way. These observations were made using telescopes both on Earth and in space. The researchers, including Leiden astronomer Sjoert van Velzen, were able to trace the neutrino to a black hole that is devouring…

The Guava Platform, which is at the centre of this PhD thesis, was initiated in 2014 as a conceptual framework of my art practice and research. The aim of the Guava Platform is to research and create possible techniques of art-actions that are part of my quest to continue to live in the conflicted landscape,…
