De geboorte van een ster: een traag en mysterieus drama
Een ster staat niet zomaar van de ene op de andere dag aan de hemel. Het ontstaan duurt enkele tienduizenden jaren. Twintig jaar geleden maakten astronomen een plaatje van een ster in zijn geboortefase. De James Webb Space Telescoop (JWST) kon diezelfde ster nu veel gedetailleerder vastleggen. Dat levert…

Optrekkende mist rond jong sterrenstelsel voor het eerst in beeld
In het vroege heelal worden sterrenstelsels omhuld door een soort mist: een wolk van waterstof. Bij stelsels in het latere heelal is die mist verdwenen. Sterrenkundige Jorryt Matthee slaagde er voor het eerst in het optrekken van die mist in beeld te brengen. Promotie op 19 september.

Prying eyes on radio skies: pushing the high-resolution low-frequency frontier with LOFAR
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.

Sterrenkundigen zien voor het eerst benzeen in planeetvormende schijf rond ster
Een internationaal team van sterrenkundigen onder wie de Leidse hoogleraar Ewine van Dishoeck heeft voor het eerst het gas benzeen (C6H6) waargenomen in een planeetvormende schijf rond een jonge ster. De waarnemingen vertellen ons meer over het ontstaan van planeten in deze schijf, zoals ook onze aarde.…

Light Weighed: On the Statistics and Systematics of Weak Gravitational Lensing
In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Giant galactic outflows and shocks in the Cosmic Web
The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…
