Research at the Leiden Institute of Physics (LION) is foundational and curiosity driven. All our scientists share a desire to increase the knowledge of the world around us, in an open atmosphere of inquiry from which innovative ideas emerge that provide applications and value for society.

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,…

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…

Within the two-year Astronomy master’s programme, you can choose from seven specialisations, ranging from fundamental or applied astronomy research in cosmology, instrumentation or data science, to combinations of astronomy research with education, management or science communication.

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…

Saskia Gras, PhD graduate from the Dual PhD Center, presents her book on Wednesday 6 June:

Er is dit jaar veel aandacht voor de ‘geboorte van Nederland’ 450 jaar geleden. Minder bekend is dat in 1572 ook de Protestantse Kerk in Nederland in de wieg lag, terwijl de Rooms-Katholieke Kerk voor een paar eeuwen schijndood werd verklaard. In het kader van de Maand van de Geschiedenis brengt het…

Onlangs verscheen het boek ‘Afgrond zonder vangnet’ van Yra van Dijk, hoogleraar Moderne Nederlandse Literatuur. In haar boek analyseert ze verschillende thema's in het werk van Arnon Grunberg.

The Cryogenics Department has a liquid helium production unit and an automatic liquid nitrogen filling plant.

Elk jaar organiseert het LIBC in samenwerking met de gemeente Leiden een Publieksdag over hersenonderzoek.

This thesis explores Breaking of Ensemble Equivalence (BEE) in random graph models by examining the spectral properties of adjacency matrices. The goal is to identify spectral characteristics that differentiate random graph ensembles, enhancing the understanding of complex network structures and beh…

Stochastic resetting is simple enough to be approached analytically, yet modifies stochastic processes in a non-trivial way.

Three major cosmology-focused missions are planned for the next decade: the Euclid space telescope, the Vera C. Rubin Observatory in Chile, and the Nancy Grace Roman Space Telescope.

Planet formation is a surprisingly homogeneous process that does not take place gradually from inside out, but that occurs everywhere at the same time in a proto-planetary disc, as Dave Lommen has discovered. He will obtain his doctorate this week based on his research into the dust around young stars…

Physicists, including Dorothea Samtleben from Leiden University, are building a giant underwater telescope to unravel the origin of neutrinos and to solve the mystery surrounding dark matter. The first detector has now been installed. Once it is finished, the telescope will be three cubic kilometres…

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

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-…

Recent study led at the Leiden Observatory has observed Orion with unprecedented detail. New data from the Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes have been used to create this stunning image showing a web of filaments in the Orion Nebula. These features appear red-hot…

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…

Tussen de sterren is niet alleen leegte. Er zweven ook stoffen als methanol en koolstofdioxide. Chemische theorieën kunnen nog niet verklaren hoe die zijn ontstaan onder omstandigheden die dat juist onmogelijk zouden moeten maken. Fedor Goumans gaat met een Veni-beurs proberen die vraag te beantwoor…
