Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

Artin L-functions associated to continuous representations of the absolute Galois group G_K of a global field K capture a lot of information about G_K as well as arithmetic properties of K.

Real-life processes are characterized by dynamics involving time. Examples are walking, sleeping, disease progress in medical treatment, and events in a workflow.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

Circumstellar discs are the reservoirs of gas and dust that surround young stars and have the potential to become planetary systems.

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

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.

Mechanical metamaterials are man-made materials which derive their unusual properties from their structure rather than their composition.

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

Studievoorlichting

In dit interdisciplinaire onderzoeksprogramma werken onderzoekers uit vijf verschillende disciplines met elkaar samen. Zij stellen zich hieronder (in het Engels) aan u voor.

Wiskunde en Natuurwetenschappen, Leids Instituut voor Onderzoek in de Natuurkunde (LION)

Eerder schreef van Dijkhuizen boeken over duistere onderwerpen als pijn, demonische bezetenheid en exorcisme. Maar voor zijn nieuwste boek koos hij een schijnbaar luchtiger onderwerp: verzoening. Maar wat blijkt, verzoening is vaak juist helemaal geen ''happy affair''. Hij vertelde erover in een podcast…

Op 3 mei jongstleden werd de 10e Niko Tinbergenlezing georganiseerd. De lezingen werden dit jaar verzorgd door Steven Pinker en Rivke Jaffe. De beelden van de lezing van Steven Pinker zijn nu online terug te kijken en daarnaast is er een fotoreportage gemaakt.

Er worden veel goede afstudeerscripties geschreven door de studenten die hun Leidse geschiedenisopleiding ermee afronden. Alleen de allerbeste scripties worden voorgedragen voor de Fruinprijs: de jaarlijkse prijs voor de beste onderzoeksmaster-, master- of Europaeumscriptie van de Opleiding Geschied…

China is een belangrijke partner voor de Universiteit Leiden. We werken samen met meer dan 20 Chinese universiteiten en in Leiden studeren zo'n 500 Chinese bachelor-, master- en PhD-studenten. Leiden heeft China aangewezen als prioriteitsland waarmee het een partnerprogramma voor langetermijnsamenwerking…

This interdisciplinary minor addresses sustainabilty challenges from a systems perspective, and investigates ways to sustain society within planetary boundaries.

Met onderzoek in de wetenschappen kun je issues die spelen in de samenleving beter begrijpen. Lees, kijk of luister naar verhalen van onze wetenschappers die vertellen over hun werk. Bij geesteswetenschappen leer je de wereld kennen!

Lezing

In een nieuwe video op het YouTube-kanaal van de faculteit Geesteswetenschappen volgen we Sophie, masterstudent Russian and Eurasian Studies. Zij loopt stage bij VPRO's OVT, een wekelijks radioprogramma that historische achtergronden biedt bij nieuws, columns en documentaires.

On April 14 we will celebrate the launch of our Faculty action plan ‘diversity and inclusivity’ with a symposium. We will present the action plan and our colleague Professor Tomas Brage will be keynote speaker. He is the Director of Education at the Physics Institute of Lund University in Sweden and…

How to bring together different footprints into an integrated family and what are the synergies? What are the roles of inventory analysis and characterization in measuring individual footprints and how these affect a footprint family? How to benchmark environmental footprints against related planetary…

The research group Politics, Culture and National Identities 1789-present investigates a wide range of national political cultures in Europe and the Americas in the 19th and 20th centuries. Instead of only analyzing high politics (the acts of governments and political parties), the research group focuses…

A neurocognitive investigation of the development of social performance monitoring in youth growing up in stressful versus non-stressful environments

This dissertation presents a new perspective on the life, work and character of the Dutch physical chemist Jacobus Henricus van ’t Hoff, first recipient of the Nobel Prize in Chemistry, and one of the most important and colourful scientists in Dutch history. The image of Van ’t Hoff that emerges from…

How can we, together international experts, define future needs of R+D contributions for innovations in the field of risk-based management of chemicals and products in a global perspective using alternative testing strategies to minimize animal tests?

How can we broaden youth participation in STEM Learning

LIACS is a partner in the EU Erasmus+ Curriculum Development for the Asian education system. The knowledge available in the field of Data Science and Artificial Intelligence education will be shared and adapted for the Asian market.

A recent study on reintroduced tigers in Panna Tiger Reserve in India reveals that risks from tigers increased more because of human behaviour and people's livestock husbandry practices.

CML-IA is a database that contains characterisation factors for life cycle impact assessment (LCIA) and is easily read by the CMLCA software program.

Investigating the contribution of interpreters, informants, hunters and guides in the making of colonial scientific knowledge.

In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).

Streptomyces present a valuable platform for natural product discovery. Lugdunomycin is a novel angucycline-derived polyketide from Streptomyces sp QL37, with unprecedented skeleton and antimicrobial activity.

Ferritin is a spherical metalloprotein, capable of storing and releasing iron in a controllable way. It is composed of a protein shell of about 12 nm and within its cavity, iron is stored in a mineral form.

Death in all types of melanomas is generally caused by metastasis. Uveal melanoma (UM) is the most common intraocular melanoma, there are currently no (patient-derived) animal models that faithfully recapitulate metastatic dissemination of UM.

The lipid membrane is a basic structural component of all living cells. Embedded in this nanometer-thin barrier, membrane proteins shape the membrane and at the same time respond to the shape of the membrane.

Consequences for sediment stability and seston trapping

The subject of this thesis, ‘Approach to Markov Operators on Spaces of Measures by Means of Equicontinuity’, combines an analytical and probabilistic approach to Markov operators.
