• Radio galaxies near the epoch of reionisation Onderzoeksoutput

  This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

• Multiple star formation: chemistry, physics and coevality Onderzoeksoutput

  Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

• Lights in a sea of darkness: constraining the nature and properties of dark matter using the stellar kinematics in the centres of ultra-faint Onderzoeksoutput

  Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

• Studying dark matter using weak gravitational lensing : from galaxies to the cosmic web Onderzoeksoutput

  Of all the mass in our Universe, 80% is thought to consist of a hypothetical and invisible substance called dark matter (DM).

• Protoplanetary disk anatomy: examining the structure and chemistry of planetary birthplaces with simple molecules Onderzoeksoutput

  This thesis examines the link between simple molecules and the underlying structure and chemistry within protoplanetary disks - the birthplaces of planets.

• Lava worlds: characterising atmospheres of impossible nature Onderzoeksoutput

  Over the last three decades, the discovery of exoplanets has revealed the boundless variety of worlds beyond our own Solar System⁠. Majority of planetary systems contain short-period planets that are larger than Earth but smaller than Neptune⁠.

• Cold gas in distant galaxies Onderzoeksoutput

  The formation and evolution of galaxies is fundamentally driven by the formation of new stars out of cold gas.

• The colours of the extreme universe Onderzoeksoutput

  This thesis presents pioneering work on the panchromatic emission of some of the most luminous galaxies in the early Universe: star forming galaxies and active galactic nuclei.

• Unveiling protostellar disk formation around low-mass stars Onderzoeksoutput

  Promotor: Prof.dr. E.F. van Dishoeck

• On a quest to discover where stellar-mass black holes merge: testing the AGN binary formation channel with spatial correlation analyses Onderzoeksoutput

  The physical origin of the dozens of stellar-mass binaries, the mergers of which have been detected by the LIGO-Virgo-KAGRA collaboration via gravitational waves, is still unknown.

• Temminck's Order. Debates on Zoological Classification: 1800-1850 Onderzoeksoutput

  “Temminck’s Order” is the scientific biography of Coenraad Jacob Temminck (1778–1850), a Dutch naturalist and the first director of ’s Rijks Museum van Natuurlijke Historie in Leiden.

• From supernovae to galaxy clusters: observing the chemical enrichment in the hot intra-cluster medium Onderzoeksoutput

  Promotor: Jelle S. Kaastra Co-promotor: Jelle de Plaa

• Hunting for the fastest stars in the Milky Way Onderzoeksoutput

  The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.

• Mind the gap: gas and dust in planet-forming disks Onderzoeksoutput

  Promotores: Prof.dr. E.F. van Dishoeck, Prof.dr. C.P. Dullemond

• Chemistry in embedded disks: setting the stage for planet formation Onderzoeksoutput

  To address the fundamental questions of how life on Earth emerged and how common life may be in the Universe, it is crucial to know the chemical composition of the planet-forming material.

• wavefront sensors for direct exoplanet imaging: Theory, simulations and on-sky demonstrations Onderzoeksoutput

  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…

• Shining Light on Interstellar Matter Onderzoeksoutput

  Promotor: H.V.J. Linnartz

• Layered loyalties: the Natuurkundige Commissie in the Netherlands Indies (1820-1850) Onderzoeksoutput

  This dissertation, Layered Loyalties: The Natuurkundige Commissie in the Netherlands Indies (1820-1850), studies the Natuurkundige Commissie.

• Bridging the gap between physics and chemistry in early stages of star formation Onderzoeksoutput

  A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.

• Painting with starlight : optical techniques for the high-contrast imaging of exoplanets Onderzoeksoutput

  This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

• Jaap Kistemaker en uraniumverrijking in Nederland 1945-1962 Onderzoeksoutput

  De Nederlandse fysicus Jaap Kistemaker slaagde er in 1952 voor de eerste keer in om uranium te verrijken.

• Tracing the journey of the sun and the solar siblings through the Milky Way Onderzoeksoutput

  Supervisor: S.F. Portegies Zwart Co-Supervisor: A.G.A. Brown

• X-ray spectroscopy of merging galaxy clusters Onderzoeksoutput

  This thesis focuses on the X-ray spectral analysis of merging galaxy clusters and the plasma code development for future high-resolution X-ray spectroscopy observations.

• Inferno Worlds Onderzoeksoutput

  A remarkable population of short period transiting rocky exoplanets with equilibrium temperatures on the order of 2,000 K has recently been discovered.

• Molecules during stellar formation and death Onderzoeksoutput
