Model-assisted robust optimization for continuous black-box problems
Uncertainty and noise are frequently-encountered obstacles in real-world applications of numerical optimization. The practice of optimization that deals with uncertainties and noise is commonly referred to as robust optimization.

Monsters in the Deep: Using simulations to understand the excess baryonic mass in the centres of high-mass, early-type galaxies
This thesis aims to enhance our understanding of galaxies by testing theoretical models of galaxy formation against observations, particularly in the cases of extreme systems which have been found to have an excess of baryonic mass in their central regions, in the form of either supermassive black holes…

Applications of AdS/CFT to strongly correlated matter: from numerics to experiments
What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

Black Theatre springlevend in Zuid-Afrika
Black Theatre, activistisch theater van en voor zwarte Zuid-Afrikanen, bloeide op onder de apartheid. Maar met de democratisering van Zuid-Afrika heeft deze kunstvorm allerminst aan belang ingeboet, meent Francis Rangoajane. Promotie op 16 november.

Black lives matter: waarom het Amerikaanse protest in Nederland resoneert
De directe aanleiding was de dood van George Floyd door politiegeweld, maar de Black Lives Matter-betogingen in de Verenigde Staten en hier in Nederland gaan over veel meer dan dat. We vroegen Karwan Fatah-Black, historicus op het gebied van de Nederlandse slavernijgeschiedenis, naar zijn analyse. ‘We…

Neutral outflows in high-redshift dusty galaxies
Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

Helpen autistische jongeren spontaan een onhandige onderzoeker?
Spontaan elkaar helpen, waarom is dit belangrijk? Het is bekend dat elkaar helpen bijdraagt aan een betere sociale band en goede contacten, en vriendschappen bestendigt. In deze studie voerden we een experiment uit waarin de onderzoeker 'per ongeluk' lucifers liet vallen. De meeste tieners hielpen mee…

Boekensalon ‘Ooggetuigen van de Nederlandse slavernij’ – met Karwan Fatah-Black en Camilla de Koning
Gruwelen van de overtocht, publieke veiling, brandmerken en dan werken op plantages in de koloniale wereld. Over het Nederlandse slavernijverleden bestaan honderden kilometers archief, maar zelden komen daarin de mannen, vrouwen en kinderen die gedwongen in slavernij leefden aan het woord.

Kleine quantumsystemen helpt kunstmatige intelligentie
Zelflerende systemen - draaiend op ‘klassieke’ computers - hebben de afgelopen vijf jaar enorme vooruitgang geboekt. Automatische vertaling van tekst of spraak zijn twee bekende voorbeelden. Leidse onderzoekers verwachten dat zelfs quantumsystemen met maar een paar dozijn qubits deze en andere soorten…

The dust and molecular gas in the torus of NGC 1068
An Active Galactic Nucleus (AGN) is a highly luminous region at the center of a galaxy, powered by the accretion into a supermassive black hole and emitting energy from radio waves to gamma rays, often outshining the host galaxy.

Black lives matter: ‘Racisme bestaat in allerlei vormen, maar is een wereldwijd probleem'
Het begon met betogingen vanwege de dood van George Floyd door politiegeweld in Minneapolis, maar de Black Lives Matter-protesten verspreiden zich snel over heel Amerika. Dagelijks gaan door heel het land duizenden mensen de straat op. We vroegen Amerika-deskundige Sara Polak hoe dat komt. ‘Na Ferguson…

Mining the kinematics of discs to hunt for planets in formation
Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…
