In this thesis, I studied the origin and evolution of the non-thermal radiation in merging galaxy clusters.

It has now been well established that shocks and turbulent motions in the intra-cluster medium (ICM) generated through cluster mergers can produce large-scale synchrotron emission.

Within the ICM 2018 project, Leiden University cooperated with 25 partner universities from 14 countries. In total, 97 mobilities were granted to this project - 65 mobilities were realised (some mobilities had to be ended prematurely due to covid-19, others were finished online).

In this thesis, I study the formation of large-scale structure and the physics of particle acceleration at large scales (~Mpc).

On Sunday 15 September 'ICM Weekendschool Den Haag' (ICM Weekend School The Hague) gathered at the Wijnhaven location for the first time.

Our in-house human skin equivalents contain all stratum corneum (SC) barrier lipid classes, but have a reduced level of free fatty acids (FAs), of which a part is mono-unsaturated. These differences lead to an altered SC lipid organization and thereby a reduced barrier function compared to human skin.…

In Film and Video Intermediality, Janna Houwen innovatively rewrites the concept of medium specificity in order to answer the questions “what is meant by video?” and “what is meant by film?”

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

A revolutionary supercomputer with energy-efficient parts that are available in the shops. Professor of Computational Astrophysics Simon Portegies Zwart has been awarded an NWO Medium Grant to build this processing giant, which will have the power of a supercomputer but requires only one percent of…

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.

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.

Polycyclic aromatic hydrocarbons (PAHs) are the most abundant class of organic compounds in space. The PAH field evolves from the constant interaction between experimentalists, theorists, modellers and observers. While laboratory research and quantum chemical calculations together set up the molecular…

Galaxies are environments where gas coalesces, cools, and is converted into stars. However, it remains unclear the exact mechanisms through which galaxies acquire, redistribute and lose their gas.

In 2015, Leiden University has been awarded an ICM grant for student and staff exchange with eight different partner countries outside Europe. In 2018 this number almost doubled to fourteen. A complete list can be found in the overview section. Here we share a couple of highlights from 2018.

Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.

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

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

Stellar feedback is a crucial ingredient in the evolution of galaxies.

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

The formation and evolution of galaxies is fundamentally driven by the formation of new stars out of cold gas.

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.
