The work presented in this thesis is based on ALMA surveys of protoplanetary disks in three star-forming regions: Lupus, OMC-2, and NGC 2024.

Diverse types of exoplanets such as gas giants on close-in orbits (hot Jupiters) and young massive giants on wide orbits (super Jupiters), with no analogs in the Solar System, pose challenges but also opportunities to our understanding of planet formation and evolution.

Circumstellar discs are the reservoirs of gas and dust that surround young stars and have the potential to become planetary systems.

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

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

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

To study how planetary systems come into existence we study much younger systems still in formation.

This thesis focuses on protoplanetary disks: flattened structures of gas and dust around young stars in which planets are expected to form and grow.

Indigenous Latin American artifacts have attracted the interest of Europeans since the earliest moment of contact between Europeans and the Indigenous peoples of the Americas. The ERC-funded BECACO project uses an innovative multidisciplinary framework to investigate the provenance of ethnographic and…

Stellar feedback is a crucial ingredient in the evolution of galaxies.

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…

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.

Following the Big Bang, structure in the Universe started collapsing under the force of gravity. This resulted in the formation of the first stars, galaxies and clusters of galaxies.

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.

This thesis focus on the interaction between M dwarf stellar winds and Galactic cosmic rays and the possible effects on the habitability of exoplanets.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

De eerste boom is geplant: op woensdag 6 maart vond de feestelijke start plaats van de aanleg van het Schilperoortpark in het Leiden Bio Science Park. Wethouder Paul Dirkse en vicevoorzitter van het college van bestuur Martijn Ridderbos plantten de boom samen met Cas Schilperoort. Hij is de kleinzoon…

De bedrijfsDocent Ontwikkel Teams voor natuurkunde, scheikunde en wiskunde zijn in maart succesvol van start gegaan.

Op 25 mei 2016 was in Museum Volkenkunde de kick-off van het project arbeidsmarktvoorbereiding van de Universiteit Leiden. Studenten, bestuurders, mensen uit het bedrijfsleven en docenten spraken over de behoefte aan en plannen voor arbeidsmarktvoorbereiding van studenten.

Het Navigatielab is gestart met een onderzoek naar de effecten van de door ons ontwikkelde navigatietraining Wayfinder. Onderzoeker Milan van der Kuil leidt dit onderzoek en bekijkt hoe het navigatievermogen van mensen met niet aangeboren hersenletsel verbeterd kan worden.

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

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…
