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…

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

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

This project studies travel writing about the Dutch East Indies written between 1800 and the end of the Second World War. By analyzing both Dutch travel texts and Indigenous travel texts in Javanese and Malay, it presents a new, double-voiced perspective on (the historiography of) the Dutch colonial…

To what extent does exoplanet Proxima b resemble our Earth? And is there some form of life present? Astronomers hope to find answers to these questions with the new European Extremely Large Telescope (ELT). An NWO research grant of €18 million will allow a Dutch consortium to continue building instruments…

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-…

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.

Teaching is a vital part of CompaRe’s activities. Both in Leiden and abroad, our aim is to educate the minds that will redesign and drive forward the regional integration of tomorrow. We do so by offering multiple courses on comparative regional integration in Leiden, the creation of a MOOC on comparative…
