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…

Turen in het diepe universum
Bernhard Brandl, de nieuwe Leidse hoogleraar Infraroodastronomie, bouwt mee aan instrumenten waarmee de grootste telescopen ter wereld worden uitgerust. Met die telescopen kan de mens in het heelal objecten observeren die soms meer dan dertien miljard jaar oud zijn. Op 26 september houdt Brandl zijn…

Astronomen zien ster met stofschijf die nog steeds groeit
Een internationaal team van sterrenkundigen waaronder ook Leidse wetenschappers publiceert het beeld van een jonge ster met een omringende stofschijf die nog steeds gevoerd wordt vanuit de omgeving. Het verschijnsel rond de ster SU Aur kan verklaren waarom zoveel exoplaneten niet netjes uitgelijnd zijn…

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.

Extremely loud & incredibly far: observing radio bright AGN into the cosmic dawn
In this thesis new methodologies are developed for the detection and systematic study of radio sources in the early universe. This allows us to gain a deeper understanding of the formation and evolution of galaxies, the activity of supermassive black holes, and the final phase transition of our universe:…

Leiden Law students are looking forward to the lawyer of the future
As Leiden Law students, we are now in the digital age, 'where we believe law and technology should go together.' After all, for us, it is important to look beyond trodden paths of established legal knowledge. The books on law and case law surely will not be sufficient for the lawyer of the future. That…

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.
