This thesis is an experimental study of the UV irradiation of the interstellar ice analogues, relevant for the different stages of the star and planet formation sequence.

This thesis is largely an experimental study on the formation of solid-state simple and complex organic molecules in the H2O-rich and CO-rich ice phases of dense interstellar clouds and dark cores.

The

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.

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

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

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.

What are the mysteries behind soft condensed matter?

Research groups in the Quantum Matter & Optics programme investigate electronic properties of matter and light-matter interactions with emphasis on quantum information.

In this thesis, we show how MRFM can usefully contribute to the field of condensed-matter.

The physics of black holes appears to be as far removed from the physics of electrons in metals as it can be.

Gold Matters: Sustainability Transformations in Artisanal and Small-scale Gold Mining: A Multi-Actor and Trans-Regional Perspective.This project explores whether a transformative approach towards sustainability can arise in Artisanal and Smallscale Gold Mining (ASGM).

At the Faculty of Humanities, we study languages, cultures, civilisations and their connection to each other. This knowledge is relevant to society and we gladly share it with the world around us.

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

Research groups in the Biological & Soft Matter Programme unravel mechanisms in biological processes and develop novel bio-inspired soft materials.

The quantum nature of matter and light has grown into a broad and fruitful research field for theorists and experimentalists alike. It combines foundational research with toward applications, the most well known of which is the quantum computer.

The Low Frequency Array enables studies of low-frequency carbon radio recombination lines with unprecedented sensitivity, spectral and spatial resolution.

Before embarking on your studies at Leiden University, it is important to thoroughly research the financial aspects of your stay. Look into the cost of living and studying in the Netherlands, and find out about all the available sources of financial aid. There are many options available.

What is neutron star matter?

Errors are everywhere, and mechanical failures are especially common: buckled grain silos and cracked support columns are, justly, seen as an issue to be avoided.

It is an established fact that the Standard Model has to be extended to explain the so-called Beyond the Standard Model (BSM) phenomena: dark matter, matter-antimatter asymmetry of the Universe and neutrino flavour oscillations.

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.

Discovering what is inside giant planets and their atmosphere, that is one of the goals of astronomer Yamila Miguel. With an ERC Consolidator Grant of 2 million euro, she will study giant planets both inside and outside our solar system. ‘We want to know more about how planetary systems are born, how…

‘Islam and Muslims are not something that happened to Europe; they are part of Europe. In fact, Islam is one the biggest constants in European history,’ argues Professor Maurits Berger in the new eight-part Matters of Humanities: History of Islam in Europe podcast series of the Leiden University Faculty…

The focus of our theoretical physics research is the nature of macroscopic matter that is in one or the other way still in the grip of quantum physics.

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

The focus of our theoretical research is understanding the behaviour of soft condensed matter, physical matter which is deformed or structurally altered by thermal fluctuations or small stresses.

Laboratory, observation and modeling work on the dissociation of polycyclic aromatic hydrocarbons in interstellar environments and the formation of new molecular species through the fragmentation process.
