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.

The thesis addresses the long-term dynamical evolution of hierarchical multiple systems.

In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.

In this thesis, we present new laboratory data of interstellar dust analogues.

One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

To observe nature at work, LUC students taking the Earth, Energy, and Sustainability major spend two weeks of their summer break in the Tauern Alps of Austria. In brief, seventeen students, two student teaching assistants, and one instructor went off-campus to explore Alpine landscapes at altitudes…

In the Phenomix Medical Delta Field Lab, which was officially opened on Thursday 9 July, scientists, healthcare institutions and businesses work together to develop innovative applications in the field of metabolomics. This research field makes it possible to determine which drugs will be effective…

Nature uses a special class of histone proteins, histone variants, to modulate the properties of chromatin at defined genomic locations.

Our group operates at the cross-roads of different disciplines: molecular and cellular microbiology, biochemistry, structural biology and biophysics. The group harbors expertise in a multitude of molecular and cellular approaches including:

When does it rain when air is oversaturated with moisture? How does an infection spread among the population? The problems that mathematician Professor Frank den Hollander tries to solve come from physics, chemistry and biology.

Marjolein van Reisen has been Institute Manager Finance for a year, and Wiesje Zikkenheiner has been Institute Manager HR for two months. This duo job is by no means a luxury in an ever-growing organisation. Marjolein: 'We’re both new to this world, so we have our hands full.'

The Joan Van der Waals colloquium is an ongoing bi-weekly lecture series.

From interpreting in Arabic and a visit to the dentist to a game of hockey. The temporary reception of 123 refugees in the University Sport Centre is running smoothly thanks to the enormous support from staff and volunteers. ‘It’s the children who most need attention.’

Dr Mike Field is the newly appointed Head of the Bioarchaeology Laboratories (Zoology, Human Osteology, and Botany). The new laboratories provide members of the Faculty with a first class infrastructure. “I see the laboratories as available for everyone to use.”

Matthew Fields, from Philadelphia, US, came to Leiden to study astronomy as part of the Euroscholars scheme. 'I came here to gain valuable research experience, and I haven't been disappointed!'

From the Big Bang to superconductivity. Many ground-breaking discoveries have been made in Leiden University’s long history.

His dissertation has been completed for more than a year, but due to corona the defence had been postponed. On Wednesday 30 September, Machiel van der Heijden will finally be able to defend his dissertation Transnational Networks and Domestic Agencies: Making Sense of Globalizing Administrative Patterns…

Archaeologist Mike Field spent his summer holiday riding in the toughest horse race in the world, the Mongol Derby: 1,000km in ten days across the Mongolian steppe, following in the footsteps of the Genghis Khan’s messengers. Field was thrown from his horse twice but managed to make it to the finish…

With the start of June, the annual Leiden Archaeology Field School has begun. Like last year, the Field School takes place in Oss. Every week, a group of 25 first year students gets to learn the ins and outs of a professional excavation.

Prof. dr. Marcel Cobussen has published a free e-pub: The Field of Musical Improvisation.

Dusted off and fresh from the field, some insight perspectives on the 2012 field season of the Proyecto Arqueologico Centro de Nicaragua. It's safe to summarize the field campaign as having generated some insights, and possible answers, many more contacts, and the occasional frustration for added bo…

All life on earth contains DNA, which is used to store biological information. Organisms compact their DNA in order for it to fit inside their cell(s).

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