On 1 September, the conference of the Kirchheiner Chair ‘Government and citizens: A matter of trust’ took place. In a packed hall in the beautiful Old Observatory of Leiden University, under the inspiring leadership of Willemien den Ouden, a debate was held on the role of the Dutch National Ombudsman,…

Please note that SP2024 uses a two-step submission process with two separate deadlines; 20 December 2023 for the abstract and 12 January 2024 for the full paper. The abstract submission (or pre-submission) is needed for the program chairs to assign your submission to reviewers with matching expertise.…

How did parties as political organizations emerge?

Multiple identities of elites and ‘commoners’ viewed through the lens of crafting from the Chalcolithic to the Iron Ages in Europe and the Mediterranean

Within 3 months of the start of the PhD project, your supervisors and you will draw up a Training and Supervision Plan in consultation with you and the other members of the supervision team. 

Research at Leiden Observatory spans the full width of modern astrophysical enquiry. It is based on observation, theory, simulation, and experiment. Two broad clusters characterize the ongoing research. Within each theme, researchers carry out their personal and specialized research programme. The two…

In this thesis we investigate cosmology and the large scale structure of the Universe using cosmological simulations.

This research focuses on the distribution of chemical elements in protoplanetary disks, the birthplaces of planets. These disks form around young stars and contain gas and dust, from which planets grow. Ice plays a crucial role in planet formation, aiding the clumping of dust particles and influencing…

This dissertation studies the formation of the wage laboring class in the Iranian oil industry during the first decades of the 20th century.

On April 26th, Kate Bellamy succesfully defended her doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Kate on this great result.

How does open government affect the level of public trust?

Hydrocarbonylation of alkenes with carboxylic acids in synthesis of carboxylic acid anhydrides is relatively less explored. We herein present a study and optimization of a palladium-catalyzed hydrocarbonylation reaction of alkenes using carboxylic acids as the nucleophile, by which acid anhydrides can…

Exploring Late Bronze Age attitudes towards martiality through experimentation and micro-wear analysis

The applications of studying the early development of insects range from agriculture to material science.

ICEHL will take place in Leiden on 7-11 June, 2021.

In this thesis, we aimed to better understand the underlying mechanisms involved in TNBC progression and metastasis formation and discover new targets to reduce breast cancer related deaths.

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

Promotores: Prof.dr. J. Kuiper, Prof.dr. P.H.A. Quax

Abdolreza Alamdar Baghini defended his thesis on 5 December 2019.

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-…

Mining the unusually rich diaries, memoirs, and poems written by Netherlandish Catholics, Judith Pollmann explores how Catholic believers experienced religious and political turmoil in the generations between Erasmus and Rubens.

Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

Invasive lobular carcinoma (ILC) is the second most common type of breast cancer.

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.

Supramolecular polymers are class of materials that are formed by non-covalent interactions such as hydrogen bonding, π-π interactions, electrostatic interactions and the hydrophobic effect.

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

The mechanism of the electrochemical reduction of dioxygen by a mononuclear pyridylalkylamine copper complex was investigated (see picture). It was shown that in neutral aqueous solution dioxygen undergoes stepwise reduction, wherein hydrogen peroxide plays a key role. The rate constants determined…

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

On Friday 15 November 2024 Chunli Song successfully defended a doctoral thesis and graduated.

Mr. Sujadi defended his thesis on 29 June 2017

PNAS publication on protein encounter complexes

Cardiovascular disease is the leading cause of death worldwide.

A key step in the synthesis of oligosaccharides and glycoconjugates is the formation of the glycosidic bond.

The Municipality of Lelystad is using a new kind of council agreement: a general agreement that all parties are entitled to have their say on. As Professor of Constitutional Law Wim Voermans recently said on Dutch current affairs programme ‘EenVandaag’, this form of agreement would also lend itself…

An international team of astronomers led by Ardjan Sturm of the Observatory has made the first two-dimensional inventory of ice in a planet-forming disk of dust and gas surrounding a young star. The researches, including Melissa McClure, used the James Webb Space Telescope and publish their findings…

The Hague Journal of Diplomacy only accepts online submission of articles through its Editorial Manager.

In Germany, the United States and even in Vietnam: all over the world, the Leiden discovery of the birth of two planets was shared. Astronomer Sebastiaan Haffert and his team were able to record multiple planets in the making for the first time and published their findings in Nature Astronomy. A unique…

Lecture, LUCL Colloquium - Series '24/'25

How can governments reach their policy goals in the most effective way? Which manner of financing is the most suitable? Does the spirit of our times call for new forms of subsidy? What does the future of subsidy law look like?

Have you had a busy week at work? If so, it’s better to take a walk in a natural environment than to go shopping in the city.

Macrophages and atherosclerotic lesions The infiltration of monocytes in the arterial wall, their differentiation to macrophages, and the subsequent accumulation of cholesterol in these macrophages initiate the process of atherosclerosis. We study the importance of specific genes in macrophages for…
