To construct catalysts that can produce fuels from CO2 innumerable times, we need to learn much more about how catalysis works. Irene Groot is conducting groundbreaking research into catalysis at the atomic level.

Inaugural lecture

Large telescopes can look so deep into the Universe that they can also look back billions of years in time. From 2018, the successor of the Hubble Space Telescope, the James Webb Space Telescope, will be able to see the period just after the Big Bang, when the first stars and galaxies formed. Astronomers…

Duizenden metaalvondsten die door detectorzoeker wijlen Herman Zomerdijk zijn gedaan in de regio Kennemerland schetsen een uniek beeld van Noord-Holland door de eeuwen heen. Hij zocht en verzamelde decennialang historische metalen objecten in Noord-Holland en bouwde zo een unieke metaalcollectie op.

These are the proposed research projects for LEAPS 2019. Please note that not all projects will go ahead and some may still be added in the near future. Final funding decisions lie with the Faculty sponsors. And please make a note that if you are interested in an ESA project, to check if your state…

We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

The nanoscale structure of a catalyst under reaction conditions determines its activity, selectivity, and stability. For the production of sustainable energy and materials, new catalysts are needed. By understanding the structure-activity relationships of catalysts under reaction conditions, insight…

Improvements of weak gravitational lensing shape measurements are presented and some used for data analysis.

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…

Plants could be regarded as small chemical factories, which produce chemical substances via photosynthesis. If we can imitate photosynthesis in an artificial system, we can make clean fuels and materials out of sunlight and CO2. Huub de Groot is very close to designing a system of this kind.

Overview of the CML reports

The long term goal of the Biophysical Organic Chemistry/SSNMR group, headed by Prof. Huub de Groot, is to reach an understanding of structure, dynamics and functional mechanisms of membrane proteins and self-organized biological assemblies and to translate this knowledge into new concepts for nano-devices,…

Astronomers want to understand the Universe, from the Big Bang to the present day, and what the future will hold. In Leiden they focus on two key questions: ‘How did stars and planets originate’ and ‘How were galaxies and black holes formed in the young Universe?’ A new generation of telescopes – just…

Stellar feedback is a crucial ingredient in the evolution of galaxies.

Supervisor: S.F. Portegies Zwart Co-Supervisor: A.G.A. Brown

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

What are the 'dark' components of the universe?

In welke mate hebben domaniale structuren de machtsvorming en nederzettingsontwikkeling in en van het gewest Holland bepaald?

Below you will find a collection of books, other than those in the BLRN book series, to which members of BLRN have contributed.

The Dutch-Japanese made DESHIMA instrument has passed its first practical tests when measuring the distances and ages of distant galaxies. The core of the instrument is a chip the size of two euro coins that measures 49 shades of far infrared light. The developers of the spectrometer publish the results…

Ariadne Schmidt, Isabelle Devos and Julie de Groot provide you with refreshing insights concerning the study on urban singles in the period between 1200 and 1900.

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.

A century ago, it was unclear whether the stars in the sky were clustered in groups, or widely spread in the universe.

One of the most important puzzles in modern astrophysics is the nature of dark matter.

The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.

How can we make the production of chlorine cheaper and more friendly for the environment?

Professor Jan Aart Scholte delivered an inaugural lecture, entitled “Governing a (Better) Global World” on Friday 4 February 2022 in the Groot Auditorium of the Academy Building, Rapenburg 73 in Leiden.

Research at the BPOC/SSNMR group is comprised of the following research themes:

We are interested in understanding the mechanics of soft materials, of which biological materials are prominent examples.

The transition to new and renewable energy sources should be completed by 2050. Researchers in various disciplines at Leiden University are conducting unique research that will help us make this transition and reduce CO2 emissions.

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.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

The solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.
