Tailoring x-ray tomography techniques for cultural heritage research
Visualizing the internal structure is a crucial step in acquiring knowledge about the origin, state, and composition of cultural heritage artifacts. Among the most powerful techniques for exposing the interior of cultural heritage objects is computed tomography (CT), a technique that computationally…

Speuren naar gepolariseerd licht in zoektocht naar buitenaards leven
Een nieuwe manier om het licht van verre planeten te analyseren zou ons bewijs kunnen leveren van buitenaardse planten, schrijft astronomie-auteur Colin Stuart in de New Scientist. In zijn artikel beschrijft hij het werk van de groep van de Leidse astronoom Rob van Holstein. Dit team detecteerde afgelopen…

Goed werkgeverschap in relatie tot medewerkerswelzijn
Goed werkgeverschap is net als goed werknemerschap een open norm. Daarmee is het onduidelijk en onzeker waar werkgevers zich op dienen te richten en welke rechten (en plichten) werknemers hebben in dat verband. De doelstelling van dit onderzoek is om invulling te geven aan de norm goed werkgeverschap…

Hoe herken je de atmosfeer van buitenaardse lavawerelden?
In de afgelopen 30 jaar zijn er ruim 5000 planeten ontdekt buiten ons zonnestelsel. Een veelvoorkomende exoplaneet is de lavawereld, een hete superaarde met oceanen van vloeibaar lava. Mantas Zilinskas ontwikkelde modellen om mogelijke atmosferen daarvan te simuleren. Die simulaties bieden houvast voor…

Tuning in to star-planet interactions at radio wavelengths
Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

High-contrast imaging polarimetry of exoplanets and circumstellar disks
Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

Untangling cosmic collisions: a study of particle acceleration and magnetic fields in merging galaxy clusters
On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.
