Cosmic tomography with weak gravitational lensing
We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

Shaping Massive Galaxies: the structural evolution of galaxies across
Galaxies in the local Universe fall into two main categories of spirals and ellipticals. In this Thesis, we explore the structural evolution of galaxies into this bimodal distribution.

Withstanding the cold: energy feedback in simulations of galaxies that include a cold interstellar medium
Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

responses to online peer conflict: How self‐evaluation and ethnicity matter
In online games conflicts between players may arise. Novin, Bos, Stevenson and Rieffe investigated factors that may explain why some adolescents react more angrily than others in this type of situation. In their realistically designed gaming environment, the (pre-programmed) fellow player suddenly started…

COMMUNITY: unraveling the regulatory networks in Streptomyces that switch on antibiotic production on demand
Through his project we will unravel the global regulatory networks that control gene expression in Streptomyces bacteria and allow them to properly respond to major changes in the environment; we will then harness this knowledge to activate and identify novel antibiotics

Exploring the Universe
Astronomers want to understand the Universe, from the Big Bang to the present day, and what the future will hold. In Leiden they focus on two key questions: ‘How did stars and planets originate’ and ‘How were galaxies and black holes formed in the young Universe?’ A new generation of telescopes – just…

Black holes with ‘dreadlocks’ offer insight into quantum matter
Physicists understand little about quantum matter, which is a building block of future quantum computers. Theorists have now discovered that black holes with ‘dreadlocks’ harbor a similarly exotic order pattern, which makes calculations on quantum matter easier. Publication in Physical Review Letter…
