The interplay between stars, gas and dust in faint star-forming galaxies
When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

De zoektocht door het heelal
Astronomen willen het heelal begrijpen, van de Oerknal tot nu, en hoe dit verder zal gaan. In Leiden concentreren ze zich daarbij op twee vragen: 'Hoe ontstaan sterren en planeten? en 'Hoe ontstonden in het jonge heelal sterrenstelsels en zwarte gaten?' Een nieuwe generatie telescopen – net klaar of…
