Galaxies are environments where gas coalesces, cools, and is converted into stars. However, it remains unclear the exact mechanisms through which galaxies acquire, redistribute and lose their gas.

Drie projecten met Leidse onderzoekers ontvangen van NWO een subsidie voor de bouw of vernieuwing van grootschalige onderzoeksfaciliteiten. Zij gaan werken aan elektronenmicroscopie, een X-omics initiatief en een röntgentelescoop. De projecten maken deel uit van de Nationale Roadmap voor Grootschalige…

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.

This thesis investigates how galaxies form and what diversifies the evolutionary histories of galaxies.

Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.

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.

In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.

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…

In this thesis, I study the formation of large-scale structure and the physics of particle acceleration at large scales (~Mpc).

Sustainable energy from wind and solar is most readily available near the sea.

Balsaminaceae is a diverse plant family characterized by a huge floral morphological diversity.

The solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.

The logic seems inescapable indeed. The bigger the population, the higher the probability it contains an Einstein. Hence, bigger populations are more likely to develop complex culture.

The growing demand of energy indicates that global energy resources in the form of fossil fuels will not be sufficient in the future. In order to solve potential future energy problems development of a sustainable hydrogen economy is highly desirable.

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

To gain more insight into the evolutionary development of orchid flowers and fruits, the orchid species Erycina pusilla was studied. The evolutionary origin of the median petaloid sepal, the callus on the labellum, and the stelidia was studied.

This thesis investigates the structural evolution and assembly of galaxies since the first few billions years after the big bang.

We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

NWO heeft vier TOP subsidies toegekend voor Leidse astronomen en één voor een Leidse wiskundige, landelijk zijn er 19 subsidies toekend aan exacte wetenschappers. De onderzoeken van prof. Xander Tielens met prof. Huub Rottgering, dr. Michiel Hogerheijde en dr. Jelle Kaastra zijn gehonoreerd met een…
