In the past decade many population studies have been performed with the Atacama Large Millimeter/submillimeter Array (ALMA) to understand the bulk properties of protoplanetary disks around young stars. These population studies mostly consisted of low mass stars, with relatively few of the disks around…

Within the field of astronomy, understanding how galaxies grow and evolve from the Big Bang to the present day is a challenging and complex question.

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

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

Op 29 april heeft een live viewing plaatsgevonden op de Spaanse Trappen van het Wijnhavengebouw in Den Haag van het ‘Spitzenkandidaten’-debat vanuit het Theater aan het Vrijthof in Maastricht tussen de kandidaten die door hun Europese politieke partij zijn aangewezen als kandidaat-voorzitter van de…

Dit onderzoek richt zich op hoe de voedselconsumptie en -verspilling van huishoudens tijdens COVID-19 werd aangepast aan de levensstijl.

On November 27-28 2025, the congress 'Disability and inclusion in the medieval city: a comparative view between Europe and the Islamic World' will be held at the university of Cantabaria, Spain. The deadline for submissions is 13 October, 2025

Anthropogenic change is reshaping ecological systems, raising concerns about increasing transmission of infectious diseases. Among these, mosquito-borne diseases may be particularly sensitive to environmental change, as their transmission depends on vector populations.

This thesis describes the development of improved formulations and alternative delivery strategies for polio vaccination.

In het academisch jaar 2023-2024 biedt het interdisciplinaire onderzoeksprogramma Sociale Veerkracht en Veiligheid vier vakken aan voor studenten die beginnen met het derde jaar van hun bachelor. Deze vakken zijn te volgen binnen de ruimte voor keuzevakken. Je kunt de vakken afzonderlijk als keuzevak…

This thesis is about augmented reality (AR). AR is commonly considered a technology that integrates virtual images into a user’s view of the real world.

This thesis explored the molecular pharmacological mechanisms of targeting CB2R via investigation of novel drug discovery concepts such as target binding kinetics, allosteric modulation and biased signaling.

Tracing the evolution of the molecular gas content in galaxies is critical for a complete understanding of galaxy formation and evolution, as it provides the direct fuel for star formation. Studies of high-redshift (z>1) molecular gas reservoirs, most commonly traced by carbon monoxide (CO), have seen…

In this thesis we push the boundaries of high-resolution imaging at radio frequencies between 100 and 200 MHz. Using the International LOFAR Telescope that spans across Europe we achieve sub-arcsecond angular resolution.

De wetenschappelijke onderbouwing van beleid wordt cruciaal geacht voor goed bestuur. Maar ondanks de overvloed aan beschikbare kennis uit onderzoek en evaluaties, weten we nog maar weinig over de daadwerkelijke invloed die dergelijke evidence heeft op overheidsbeleid. Het onderzoeksprogramma ‘Power…

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.

The work presented in this thesis is based on ALMA surveys of protoplanetary disks in three star-forming regions: Lupus, OMC-2, and NGC 2024.

In times of hardships or crisis, local people know how to deal with it using their resourcefulness. Although efforts are sometimes made by the government to help them, they are fully aware that community support is at least equally important.

Including modelling as part of software development appears to have various benefits.

“Temminck’s Order” is the scientific biography of Coenraad Jacob Temminck (1778–1850), a Dutch naturalist and the first director of ’s Rijks Museum van Natuurlijke Historie in Leiden.

In this Yearbook you will find some fascinating examples of what was done in 2021, not only by ourselves, but also by our international colleagues.

Self-assembly is an abundant process in nature and is vital to many processes in living organisms.

Electrocatalysis allows for storing electricity or converting it into chemical bonds, producing chemical building blocks and fuels using renewable resources.

The sequence-dependence of biomolecular interactions involving nucleic acids and proteins is essential for numerous processes inside the cell. Insights into the underlying molecular mechanisms have been obtained using various biochemical and biophysical methods on two different levels — bulk and sin…

Where does the urge to collect come from? What are the explicit or underlying reasons for gathering large amount of objects?

One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

My work focuses on a class of astronomical objects called protoplanetary disks.

This collection of papers was compiled in celebration of the remarkable academic career of Professor Wil Roebroeks, who has established himself as one of Europe’s leading figures in Palaeolithic archaeology over the past three decades and founded the Human origins research group at Leiden University…
