In this thesis, we use low-frequency and high-frequency radio observations to address the following questions regarding quasars: is the radio loud/quiet quasar dichotomy real?

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.

Scattering of light in the presence of nano-structured materials, i.e. with features in the order of the wavelength of the light or smaller, reveals details of how light interacts with matter at the nanoscale.

Today, knowledge is the most crucial element to stimulate organizational competitiveness and economic development.

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.

Physics and Engineering Approaches to Biomedicine and Pharmacology

This thesis revolves around the electronic spectroscopy of molecules in the laboratory and the search for the carriers of the diffuse interstellar bands (DIBs).

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

Astronomers from Leiden Observatory have developed a new method to find distant quasars and better distinguish them from other objects that look like them, using machine learning techniques. The research result has been accepted for publication in the journal Astronomy & Astrophysics. It is the last…

The Dutch atlas with pesticides concentrations in surface waters have been overhauled. This new, free accessible, website is in line with the European Framework Directive on Water (In Dutch: KRW).

Meet the newest Full Professor at the Leiden Observatory: Joe Hennawi. All the way from Santa Barbara, California, Hennawi will strengthen the astronomy institute. In Leiden, he will use his recent ERC Advanced Grant to study how supermassive black holes come into existence.

We have conducted a full spectral line survey of the 3-13 micron region of two massive protostars, AFGL 2591 and AFGL 2136, for the first time at high spectral resolution.

Vast, often populated, areas in dryland ecosystems face the dangers of desertification.

This article on private active cyber defense by Dennis Broeders is part of a special issue of the Journal of Cybersecurity, based on a selection of contributions taken from the 2019 Conference on Cyber Norms organized by The Hague Program for Cyber Norms.

The parliamentary elections in the Netherlands, scheduled for March 2017, are likely to result in a fragmented parliament and a complicated coalition formation process, according to Dutch political scientist Hans Vollaard (Leiden University).

It appears to be a paradox: ultra-thin material that absorbs all the incident light. Nonetheless, it does exist. Two Leiden researchers report on their research in ‘Applied Physics Letters’. The article is among the Top 20 of the most downloaded articles of this reputable journal in May.

Astronomers from, among others, SRON and Leiden Observatory have discovered long-sought intergalactic gas with ESA’s space telescope XMM-Newton. This gas is one of the pieces of the puzzle to map the total amount of ‘normal’ matter in the universe. The research will be published in Nature on 21 June…

This article traces the evolution of interpretations of international law and international cyber norms on responsible state behaviour in cyberspace by reassessing five major – and allegedly state-led – cyber operations: Stuxnet 2010; Belgacom 2013-2014, the Ukrainian power grid 2015, the US presidential…

Research on art is often compared to other forms of scientific research. Professor Henk Borgdorff believes that's unfortunate. 'Research on art is absolutely one of the front lines of science.' Inaugural lecture 10 February.

Marie Curie once said: I have no dress except the one I wear every day. If you are going to be kind enough to give me one, please let it be practical and dark so that I can put it on afterwards to go to the laboratory.

A team of astronomers of Leiden University and the University of Texas (Austin, United States) has discovered a new way to map distant galaxies. They did so by observing the fingerprint of oxygen in a distant galaxy, something that is usually not possible from Earth. The researchers will publish their…
