This thesis concerns the relation bettween the good reduction of Shimura varieties and the associated loop groups.

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.

A team of Leiden astronomers has managed to calculate the first 100 million years of the history of the Oort cloud in its entirety. Until now, only parts of the history had been studied separately. The cloud, with roughly 100 billion comet-like objects, forms an enormous shell at the edge of our solar…

He discovered how to determine the rotation and centre of our Milky Way, predicted where comets come from and laid the groundwork for radio astronomy: Leiden Professor of Astronomy Jan Hendrik Oort (1900 – 1992). Piet van der Kruit, whose PhD supervisor was Oort himself, has written a biography about…

The success of Dutch radio astronomy in the last century was largely due to Leiden astronomer Jan Hendrik Oort. He made astute use of circumstances in the post-war period. Historian Astrid Elbers' research focuses on this golden period.

Whether finding signals of dark matter or discovering hydrogen in the vicinity of exoplanets, Leiden astronomers are world players in their field, and they are part of a long tradition: Leiden was the first university in the world to have its own observatory.

For two decades, language experts were certain that babies were able to learn language rules from as young as the age of seven months. However, recent research carried out by a consortium of four Dutch baby labs led by researchers from Leiden cast doubts on this certainty. We spoke to researchers Andreea…
