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.

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:…

Who Owns the Hills? Ownership, Inequality, and Communal Sharing in the Borderlands of India
In his historical analysis of upland societies of the Zomia massif, James Scott (2009) emphasizes how the modern state strives to control and “make taxable” all of its subjects. For Tania Murray Li (2014), the development of neoliberal markets is the primary driver of change, as she shows based on long-term…

Astronomers see two planets vacuuming around young star
Astronomers led by Leiden astronomer Sebastiaan Haffert have directly imaged two planets that are gravitationally carving out a wide gap within a planet-forming disk surrounding a young star. While over a dozen exoplanets have been directly imaged, this is only the second multi-planet system to be p…

Giant cosmic tsunami wakes up comatose galaxies
Galaxies are often found in clusters, which contain many “red and dead” members that stopped forming stars in the distant past. Now, an international team of astronomers, led by Andra Stroe of Leiden Observatory and David Sobral of Leiden and the University of Lisbon, has discovered that these comatose…

Focal-plane wavefront sensors for direct exoplanet imaging: Theory, simulations and on-sky demonstrations
One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…
