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.

This thesis utilises the exceptional sensitivity and resolution of LOFAR to explore the low-frequency Universe, while simultaneously advancing the telescope's capabilities to enable new scientific discovery.

The Institute of Criminal Law and Criminology’s ‘Vulnerable Groups and Inequality’ research project draws on a number of disciplines.

Besides the Hortus being a beautiful place where visitors can relax and learn more about plants, we also facilitate botanical research. At the botanic garden, our ‘Living Botany’ research group investigates (plant) biodiversity and the relationship between plants and people.

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

Noah Millman defended his thesis on 26 May 2015

The research group on governance of crises studies phenomena, dynamics and actors related to crisis governance. The Leiden University Crisis Research Center (CRC) is part of this Research Group.

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.

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.

In this dissertation, the life account is constructed of of the founder of Bon Religion, Shenrab Miwo.

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.

We examine the effect of social learning on emotional competence in children and adolescents with a typical or atypical development.

The University of Groningen is organizing a summer school on the topic of Medieval “Lived Religion” this summer. In this interdisciplinary summer school Masters and PhD students will be challenged by leading specialists dealing with textual and material sources of medieval religious cultures. They will…

Researchers at Leiden study group behaviour. One of their findings is that when people make sacrifices for another member of their group, it is probably instinctive. Insights of this kind enable us to better understand and influence the social processes in a neighbourhood or company.

When a physical system possesses symmetries, these are often accompanied by a representation of the symmetry group on a Hilbert space. Group representations on Hilbert spaces have been extensively studied.

This work analyzes ritual practices and knowledge related to the Mesoamerican calendar with the aim of contributing to the understanding of the use and conceptualization of this calendar system in the contemporary K’iche’ community of Momostenango, in the Highlands of Guatemala.

Collaboration is increasingly common among teachers in schools. As such, teacher education should prepare prospective teachers to effectively interact with other teachers in different types of communities or groups.

Terrorist groups adapt to environmental changes to maintain power. This project provides new insights by developing a theory of strategic target selection and using big data analytics and machine learning to test these hypotheses.

The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…
