The theme of the Heritage Open Days Leiden on 10 and 11 September is sustainability. At four University locations guides will talk about the history of the buildings and how they have been renovated. And there is a first: tours in sign language.

This thesis investigates the relations between metabolism and anatomy through the use of Magnetic Resonance Imaging (MRI).

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

The redox-conversion reaction of metal-disulfide and metal-thiolate complexes are important, as they may shed light on electron-transfer reactions that often occur in Nature.

On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.

A remarkable population of short period transiting rocky exoplanets with equilibrium temperatures on the order of 2,000 K has recently been discovered.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

Subproject of the NWO Smart Culture Grant research project 'The Critical Visitor'.

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

How do humans control their thoughts and actions, and what can high-field brain scanning reveal about the underlying processes?

Northern lights, stellar winds and exoplanets. This is what astronomer's PhD research revolved around. PhD candidate astronomer Rob Kavanagh developed mathematical models to better understand the interactions between exoplanets and stellar winds and to define features of exoplanets. He will receive…

The insights leading to the present project firstly manifested themselves in 2008, when I worked with field recordings on the basis of relatively well-established notions in music composition studies, such as ‘musical material’ and écriture. With hindsight, I understand the outcomes of those first experiments…

In this thesis, we show that we can use Shimura’s CM theory to explicitly compute the Hilbert class field of any primitive quartic CM field.

Reducing greenhouse gas emissions is one of the most pressing challenges that humanity faces in the coming decades.

The month of October saw LUGO host an active Green Morning to celebrate the opening of the largest green solar roof of the Benelux (located on the rooftop of the Snellius building!).

The west side of the campus square is occupied by the Lecture Hall, known as ‘the dish’. This building houses the largest lecture halls of Leiden University, which welcome hundreds of students every day. It also has Leiden’s largest solar panel roof, with 1241 solar panels.

This project, commissioned by DG Research and Innovation, aims to provide information for policies that lead to the creation and improvement of the conditions which will allow researchers and European industries to safely master the properties of nanomaterials and to innovate with nanotechnology.

Leiden Professor of Number Theory Manjul Bhargava has been awarded a Fields Medal, widely regarded as the Nobel Prize for Maths. Bhargava is a professor in Princeton, and since 2010 has also been the holder of the Stieltjes chair in Leiden.

How can complexity science advance intelligence transformation?

This book provides the answers, presenting clear insights into the current state of affairs and exploring future prospects.

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.

Hastings College of the Law and Leiden Law School have a longstanding exchange programme. Each year students participate in the existing student exchange programmes. Likewise professors from Hastings College of Law have been visiting Leiden Law School and vice versa.

Leiden University has participated in an international study carried out by the CARMENES consortium, which has discovered two small, terrestrial planets around Teegarden’s Star. The planets have masses similar to Earth and their temperatures could be mild enough to sustain liquid water on their surf…

On the 14th and 15th of March, we, the students of Security Studies, went on a field trip to the National Coordinator for Security and Counterterrorism (NCTV) in the Ministry of Justice and Security.

The thesis explores how interstellar chemistry evolves as a function of time and changing physical architectures during the formation of stars.

In 2021, Leiden University will develop a new Sustainability Vision 2030. This vision for the future focuses on the primary tasks of the University: integration and visibility of sustainability in our education and research.

With the recent rise and fall of IS, academics and policy makers around the world are expressing concerns about the fate of children of former foreign fighters. Will they follow in their parents’ footsteps? In this paper, Layla van Wieringen, Daan Weggemans and Marieke Liem argue that in light of this…

This work represents the final results of several years of research within the Maya region. It deals with the relations between architecture and urbanism with landscape and astronomy.

Over the past years it has been discovered that the population of extra-solar planets is large and diverse.

Quantum computers are a proposed fundamentally new type of computer. They aim to perform some computations much faster than previously possible by exploiting phenomena at the quantum scale, called superposition and entanglement.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

During the development of the Humanities Campus, many aspects of sustainability are combined. For example:

Phase 2A of the Gorlaeus Building has, like phase 1, been developed and delivered according to high sustainability standards. The building has achieved a BREEAM-NL Very Good certification.

What is Leiden University doing to reduce energy consumption and move away from fossil energy? Where can you find information about energy? And what changes can you make yourself?

Is there extra-terrestrial life out there? It now looks as though we can sketch out an answer to this enduring question. Leiden Observatory is helping to build new instruments to find the most promising exoplanets.

The four thousand war victims buried at the Netherlands Field of Honour at Loenen include a number of Leiden students who were in the Resistance. The War Graves Foundation is looking for volunteers to take part in a special event to honour the deceased.
