We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…

Galaxies in the Universe are distributed along the intricate framework of the Cosmic Web. Groups and clusters of galaxies comprise the densest regions in this network, and therefore, are excellent cosmic laboratories to study different aspects of galaxy evolution in extreme environments.

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.

Evolutie is elke dag om je heen. Dat is de boodschap van de nieuwe Massive Open Online Course (MOOC) van de Universiteit Leiden en Naturalis die 19 september van start gaat.

Radio jets are important to the evoultion of galaxies. However, it is still not fully understood how a radio jet can be triggered.

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

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…

Taxonomy as a science has accumulated data and knowledge for more than 250 years.

In this dissertation iron-based homogeneous catalysts were synthesized, characterized and investigated for water oxidation activity.

This dissertation studies the Asymptotics of Bayesian nonparametric inference for Gaussian linear models.

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…

Climate change is one of the largest challenges faced by humanity. To combat this research into alternatives to fossil fuels is ongoing. Dihydrogen is considered a good alternative fuel, since its burning only forms water.

To design the ideal water oxidation catalyst, understanding of the catalytic mechanism and decomposition pathways is essential.

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.

Dr. Helen Pluut heeft een artikel gepubliceerd in het gerenommeerde tijdschrift Organizational Behavior and Human Decision Processes (OBHDP) in samenwerking met Remus Ilies (National University of Singapore), Petru Curşeu (Open Universiteit en Babeş-Bolyai University) en Yukun Liu (University of Western…

This thesis investigates the evolution and fate of gaseous exoplanets, which are continuously shaped by stellar activity across both short and long timescales.

One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

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…

Voltammetry plays a crucial role in modern scientific research by offering valuable insights into the electrochemical properties of materials, with wide-ranging applications in fields such as materials science, energy storage, corrosion studies, and sensor development.

Within the field of astronomy, understanding how galaxies grow and evolve from the Big Bang to the present day is a challenging and complex question.

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

Vanuit Leiden de eerste reactie op de opening van het promovendidiscours. Charlotte de Roon en Gijs van Houwelingen wijzen op de onderbelichte rol van de buitenpromovendus in de connectie tussen maatschappij en wetenschap.

In this dissertation, the synthesis and characterization of a series of iron complexes based on different ligand platforms are described.

When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

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

Een wereldwijd biologisch onderzoek heeft het meest directe bewijs tot nu toe geleverd dat mensen, en specifiek steden, de aanjager zijn van evolutionaire veranderingen op Aarde. De Universiteit Leiden, Naturalis en de gemeente Leiden droegen inhoudelijk en financieel bij aan de studie.

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.
