This project involves research into the oeuvre of the Sundanese sculptor Iko, who has worked for the Catholic mission in Java and has carved sculptures for a chapel and church in Ganjuran. The images were designed by the Catholic layman Jos Schmutzer and are characterized by a fusion in style and symbolism…

Automated government decisions can be cost-effective. But using algorithms also makes understanding the reasons behind decisions particularly complicated. Dr Melanie Fink, Assistant Professor at Leiden Law School, has received a Veni grant to fund her research into this.

More papers, more grants, more students: constant growth is still the gold standard at universities. Neuroscientists Anne Urai and Claire Kelly argue that this mentality obstructs us in resolving such complex societal problems as the climate crisis. Their alternative? The university as a doughnut.

A signal that is present both in the centre of our Milky Way and in distant places in the universe could reveal the origin of dark matter. This is what Leiden physicist Alexey Boyarsky concludes in an article in Physical Review Letters.

Decent work involves opportunities for work that delivers a fair income, care for occupational health and safety, freedom for people to organize and equality of opportunity and treatment for all women and men. The Labour Law department at Leiden University conducts research and provides education on…

This thesis is comprised of three chapters covering the theme of studying semistable varieties by looking at their dual combinatorial objects.

A post-colonial approach to the concept of time in the past and present Maya culture

The European Space Agency (ESA) introduces the members of the European Center for Space Law (ECSL) on its website through interviews with its members. One of those members is Tanja Masson-Zwaan.

Shifting the Compass: Pluricontinental Connections in Dutch Colonial and Postcolonial Literature

Voor zowel archeologen, paleontologen en geologen als vrijwilligers in de archeologie en paleontologie is het geen verrassing meer dat op de stranden van de Nederlandse kust fraaie vondsten gedaan kunnen worden. Vele artikelen, boeken, tentoonstellingen, congressen, lezingen, ‘zoekdagen’, krantenberichten,…

Op maandag 1 april 2024 stierf onze leermeester, vriend en gewaardeerd collega Dr. Alexander Hendrik de Groot (Sander).

This is an Erasmus+ International Credit Mobility project of Leiden University’s Faculty of Science with two Nigerian universities, the Center for Basic Space Science and University of Nigeria.

Researchers at Leiden Observatory study the fundamental physics that creates structure in the Universe. These processes collect matter into galaxies and gas into stars. With the use of powerful telescopes and advanced calculations and computer simulations, Leiden astronomers seek to understand the origin,…

Why do flowers often smell so wonderful? And some other plants are very horrible? Come smell it, see it and discover it in the visitor center in the Old Observatory. Suitable for young and old.

In 2015, Jorryt Matthee thought he discovered an extremely distant galaxy called CR7, which lacked elements heavier than helium. Three years later, he shows with measurements using the ALMA telescope that the galaxy does have carbon after all, and even in normal concentrations. The American Astronomical…

Afgelopen zondagavond, 22 augustus, is na een kort ziekbed onze zeer gewaardeerde collega professor Wim Jiskoot, Hoogleraar Technologie van toediening van medicijnen, overleden. Wim werd twee weken geleden onverwachts geconfronteerd met het feit dat hij een vergevorderd stadium van kanker had, waarvoor…

Over the past few months, Urban Studies students have been helping to think about the realisation of the Humanities Campus. To test their knowledge in practice, the future urban specialists gave advice on several different aspects, including thermal energy storage and the new central campus building…

On 16 January 2018, the Asia-Pacific Research and Training Network on Trade (ARTNeT) published Fengan Jiang's (Richard) working paper entitled 'Export restrictions and policy space for sustainable development: Lessons from trends in the regulation of export restrictions (2012-2016)''.

In this 'Educatip's column, psychology teachers share their key insights about work. This time: course coordinator Evelien Broekhof received support from teaching assistant Vincent during the last term. ‘I have more room in my schedule now that I don't have to do everything alone anymore.’

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

Promotores: F.H. van Lunteren, F.P. Israel

The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

Planets are formed in disks of gas and dust around young stars.

In this thesis new methodologies are developed for the detection and systematic study of radio sources in the early universe. This allows us to gain a deeper understanding of the formation and evolution of galaxies, the activity of supermassive black holes, and the final phase transition of our universe:…

This thesis focus on the interaction between M dwarf stellar winds and Galactic cosmic rays and the possible effects on the habitability of exoplanets.

The Leidse Weer en Sterrenkunde Kring (LWSK) is a society of amateurs interested in astronomy, space travel and meteorology. The association organises a monthly lecture on a fascinating subject, given by an expert in the field.

Promotor: Christoph U. Keller, Co-promotores: Matthew A. Kenworthy, Frans Snik

In this thesis, I study the formation of large-scale structure and the physics of particle acceleration at large scales (~Mpc).

This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.

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

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

The Jeugdwerkgroep is a national astronomy association for young people who are interested in astronomy. The Leiden section organizes a monthly meeting in the Old Observatory Leiden.

Tanja heeft zich sedert 1985 met haar bijzondere en veelzijdige talenten ingezet voor het opbouwen van het internationaal Instituut voor Lucht- en Ruimterecht, waarvan zij vanaf de oprichting codirecteur is.

The moon exerts a pull on us. The Americans won the space race and were first to land there. In the Universiteit van Nederland, space law expert Tanja Masson explores the questions that this raises. Who owns the moon and the valuable resources that are found there?

We are delighted that our annual "Science to Experience" exhibition will again take place, hosted by the V2_ Lab for the Unstable Media. Students were challenged to communicate their own science-inspired statements as experiences within the exhibition, this year along the theme "MUTATE".

Over the last three decades, the discovery of exoplanets has revealed the boundless variety of worlds beyond our own Solar System⁠. Majority of planetary systems contain short-period planets that are larger than Earth but smaller than Neptune⁠.

It has now been well established that shocks and turbulent motions in the intra-cluster medium (ICM) generated through cluster mergers can produce large-scale synchrotron emission.

For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.
