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?

Tijdens de Nationale Dodenherdenking op de Dam in Amsterdam was dit jaar spoken word te horen. In de Volkskrant duidt emeritus hoogleraar Mineke Schipper de herkomst van dit genre.

De natuurkundigen Carlo Beenakker en Dirk Bouwmeester spraken over kwantumverstrengeling op een mini-symposium van de Koninklijke Nederlandse Akademie van Wetenschappen (KNAW). Zij legden uit dat er een ‘spookachtige’ verstrengeling bestaat tussen elementaire deeltjes, en hoe we daar nuttig gebruik…

OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.

This thesis focuses on addressing four research problems in designing embedded streaming systems.

The majority (80%) of e-waste generated globally are recycled informally in developing countries.

1) Assess the trends in supply and production status of these critical minerals and mineral products worldwide and Europe’s dependence including on intermediate products such as permanent magnets, RE based super alloys, batteries, polishing compounds, phosphors, catalysts etc. 2) Trace the entire value…

High-angular-resolution observations of the circumstellar material have uncovered numerous and very diverse substructures in protoplanetary discs, raising the question of whether they are caused by forming planets or other mechanisms.

By documenting lexical and morpho-syntactic patterns among P’urhepecha speakers in Mexico and the US diaspora, this project will investigate the sources of language variation. The ensuing online dialect atlas will serve as an online resource for speakers, learners and researchers of the language.

Op een regenachtige avond een horrorfilm aanzetten. Wie vindt dat nou niet heerlijk? Gelukkig is het maar fictie – of niet? Volgens universitair docent Evert Jan van Leeuwen zegt moderne horror meer over onze samenleving dan wij denken. Hij is voor zijn onderzoek naar spullenverslaving in horror genomineerd…

Nieuwe krachtige telescopen, zoals de European Extremely Large Telescope, zullen de atmosferen van aardachtige planeten gaan ontrafelen met behulp van nieuwe waarneemmethoden zoals onder ontwikkeling in Leiden. Zuurstof kan dan mogelijk als eerste bewijs dienen voor buitenaards leven.

Op 12 april 2022 is Raisa Blommestijn gepromoveerd op haar proefschrift, getiteld Het spook van Weimar. Een democratie in crisis.

Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

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

A plasma is an ionized gas with very low electrical resistivity. As such, magnetic field lines are 'frozen in' and move with the fluid. Magnetic field lines that are linked, knotted and tangled, cannot be undone by the fluid motions.

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

This thesis takes steps toward understanding the interaction between gas-phase and solid-state molecules in star- and planet-forming regions.

Developing robust algorithms and theory for establishing cause-effect relationships from observational data that scale up to large data sets

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…

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.
