Withstanding the cold: energy feedback in simulations of galaxies that include a cold interstellar medium
Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

Resolving the building blocks of galaxies in space and time
We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

Tuning in to the feedback bassline: revealing the operation of AGNs in galaxy clusters with high-resolution radio observations
Following the Big Bang, structure in the Universe started collapsing under the force of gravity. This resulted in the formation of the first stars, galaxies and clusters of galaxies.

Mathematical model helps to explain the formation of spine and ribs
Mathematical biologists from Leiden have developed a model that helps to explain how the spine and vertebrae, among other things, form during embryonic development. The same process, the other way around, plays a key role in cancer metastasis. Publication in iScience.

Towards molecular complexity in birth places of stars: Formaldehyde formation from carbon atoms reacting with water ice
Scientists at Leiden University (Netherlands), Stuttgart University (Germany) and Ural Federal University (Russia) have successfully put forward a novel, computed, reaction mechanism that was experimentally tested and show that formaldehyde is formed at much earlier stages in the birthplaces of stars…

Profile 5. The Military Orders in the Netherlands up to 1600
Fighting for the faith, caring for the sick, and praying for the soul of their benefactors were the main tasks of the military orders, who since the time of the crusades were well represented in the Netherlands in the Middle Ages, including the Frisian lands. Especially the Hospitallers and the Teutonic…

De eerste mensen in de Lage Landen
Nederland ligt in de periferie van het verhaal van menswording. De evolutie van onze familie vindt lang exclusief in Afrika plaats. En, als Europa eenmaal bewoond wordt door mensachtigen, ligt het zwaartepunt ten zuiden van onze streken. Toch heeft ons land een aantal interessante vindplaatsen en vondsten…

An Economic History of Portugal, 1143–2010
This book rovides an economic history of Portugal over the course of eight centuries, from 1143 through to 2010 and situates Portugal's economic growth within the context of European development. It also responds to fundamental questions about when, how and why the economy expanded, stagnated or co…

Making Sense of Illustrated Handwritten Archives
Many handwritten and illustrated archives contain a wealth of information, but are largely underexplored because they are complex and difficult for computers to decipher. The aim of this project is to develop a digital environment that resolves this challenge and connects heterogeneous archival content…

Interstellar Catalysts and the PAH universe
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.

Neutral outflows in high-redshift dusty galaxies
Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

Geometry of Vegetation Pattern
One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.
