Home workers experience less time pressure and feel better as a result. This appears from PhD research conducted by Maral Darouei, who defends her dissertation from home on 9 June.

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.

During the Faculty of Archaeology’s 2018 Field School excavation, in Leiden, two Early Medieval burials were encountered, as well as some house plans. One of the burials was found by Beatriz, an international student from Mexico. “When I found the pelvis bone it was clear that I had found a human sk…

This project applies a social-historical approach to examine and contrast various groups of African-American slave refugees who sought freedom within North America between 1800 and 1860. It innovatively distinguishes between different “spaces of freedom” for runaway slaves, namely sites of formal, semi-formal,…

For optimization problems, it is often unclear how to choose the most appropriate optimization algorithm. As such, rigorous benchmarking practices are critical to ensure we can gain as much insight into the strengths and weaknesses of these types of algorithms.

In Quantum mechanics, particles can be in multiple positions simultaneously. Yet, when a measurement is made, the particle is found only in one place. Technology has come to a point where we may design experiments that will tell us how.

The project examines the political conflict in the Red River Valley of Louisiana between the majority-black Republican Party and the overwhelmingly white Democratic Party by studying the composition and actions of each party.

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

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

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 first photo of a black hole and measuring anxiety in the brain... From 13 until 22 May we're serving a free slice of science with your pizza.

On Tuesday 9 June 2020, researcher Maral Darouei defended her PhD thesis on sustainable careers. A large part of her research dealt with working from home.

Stuck at home with little to do? Don’t worry, because we have the perfect space related activities you can do from home, alone or with your family, in Dutch or English.

New ways of working like working from home can have a positive impact on a person’s career, but only when their superior supports their choice. Researcher Maral Darouei will defend her PhD thesis on sustainable careers on 9 June 2020.

They hurtle along at over a thousand kilometres per second: the fastest stars in the Milky Way. PhD candidate Fraser Evans conducted research into these elusive hypervelocity stars and discovered that they have a lot to teach us, about black holes and supernovae, for example.

This is an Erasmus+ International Credit Mobility project of Leiden University’s Faculty of Humanities with Anton de Kom University in Suriname.

From a white leather armchair, on which Barack Obama once sat, Dean Michiel Kreutzer opened the academic year. This time not with visitors, but completely corona-proof via a live stream. In a homely setting, Kreutzer spoke with several guests, including Covid-19 researcher Thomas Hankemeier and brand…

In the South African context, certain iconic images have been a dominant source for public understandings of historical events. The emphasis given these images tends to overshadow the historical value of other more personal photographic sources – like studio or amateur photography. This project looks…

The Netherlands Institute in Morocco is moving to a new location in the Moroccan capital, Rabat. Following a complete renovation of the building, the doors of the new NIMAR Rabat will open in September 2016.

The new Erfgoed Gezocht/Heritage Quest website means you can play armchair detective and hunt for undiscovered burial mounds in the Veluwe. This will help stop them being destroyed by construction projects. The website is the initiative of the Leiden University Faculty of Archaeology in collaboration…

Lecturers had a week to convert their courses to online teaching. An enormous challenge because remote teaching definitely wasn’t commonplace at Leiden University, and some lecturers have to share their ‘lecture hall’ with their children or partners. Alexander Pleijter, a lecturer in Journalism and…

Macrophages and atherosclerotic lesions The infiltration of monocytes in the arterial wall, their differentiation to macrophages, and the subsequent accumulation of cholesterol in these macrophages initiate the process of atherosclerosis. We study the importance of specific genes in macrophages for…

This thesis investigates how galaxies form and what diversifies the evolutionary histories of galaxies.

A high performance computer or supercomputer owes its massive processing capacity to the fact that it chops a single overarching task into a whole series of smaller tasks. It simultaneously tackles each of those smaller problems.

Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

Meet Thomas King, alumnus BA International Studies: ‘I’m currently living in London which is a really amazing experience! I’m a British citizen and I moved to the Netherlands to study BA International Studies back in 2017. I had the best three years ever living in The Hague and studying at Leiden.’

The Summer School in Languages and Linguistics has been a regular event on the Leiden Centre for Linguistics calendar for over 14 years.

Smart algorithms and powerful processors are just as essential for astronomy as big telescopes. Astronomers at Leiden University therefore constantly operate at the interface between astronomy and data science.

Existing work in probabilistic language modeling can be mostly divided into two categories:
