For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.

Planets are formed in disks of gas and dust around young stars.

This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

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.

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

My work is motivated by the necessity to extend Standard Model of Particle Physics in order to explain three observed phenomena that this great theory fails to accommodate

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

It has now been well established that shocks and turbulent motions in the intra-cluster medium (ICM) generated through cluster mergers can produce large-scale synchrotron emission.

The Jeugdwerkgroep is a national astronomy association for young people who are interested in astronomy. The Leiden section organizes a monthly meeting in the Old Observatory Leiden.

On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.

The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

Over the last three decades, the discovery of exoplanets has revealed the boundless variety of worlds beyond our own Solar System⁠. Majority of planetary systems contain short-period planets that are larger than Earth but smaller than Neptune⁠.

The Leidse Weer en Sterrenkunde Kring (LWSK) is a society of amateurs interested in astronomy, space travel and meteorology. The association organises a monthly lecture on a fascinating subject, given by an expert in the field.

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

Welcome to the Hensen Lab! We are a young dynamic experimental research group starting at the Leiden Institute of Physics. Our lab addresses one of the key challenges of modern physics: understanding the interface between quantum mechanics and general relativity.

The Leiden Science Young Talent Award celebrates a student who completed their bachelor’s degree with an outstanding thesis.

We are delighted that our annual "Science to Experience" exhibition will again take place, hosted by the V2_ Lab for the Unstable Media. Students were challenged to communicate their own science-inspired statements as experiences within the exhibition, this year along the theme "MUTATE".

On 16 January 2018, the Asia-Pacific Research and Training Network on Trade (ARTNeT) published Fengan Jiang's (Richard) working paper entitled 'Export restrictions and policy space for sustainable development: Lessons from trends in the regulation of export restrictions (2012-2016)''.

In this thesis, we address two problems concerning the tautological rings of the moduli space of curves.

An international team of astronomers from Leiden Observatory and others, has for the first time mapped a piece of the dark, cosmic web. The research strengthens the hypothesis that the young universe consisted of huge numbers of small groups of newly formed stars. The astronomers publish their findings…

On Tuesday October 11th, ACPA’s PhD-candidate Frank Blokland will publicly defend his thesis “On the origin of patterning in movable Latin type: Renaissance standardisation, systematisation, and unitisation of textura and roman type”.

To strenghten ties with the public, press, other academics and wider society, LION employs an outreach officer.

We are a dynamic research group at the Leiden Institute of Physics. Our aim is to explore and understand quantum materials, including strange metals, high-temperature superconductors, and quantum critical electron matter.

During the bachelor’s programme Astronomy you will immerse yourself in questions about our universe. Questions such as: ‘what happens in a black hole?’ and ‘what is dark matter?’ In doing so you will learn to apply mathematics and physics to astronomical problems and you will work with computer simulations…

This thesis takes steps toward understanding the interaction between gas-phase and solid-state molecules in star- and planet-forming regions.

The Tatiana Afanassjewa-lecture series was a series of public talks in Dutch that was started during the Covid-19 lockdown. The talks were given by Leiden physicists on wednesday evenings, intended for everyone with an interest in physics.

The High-Tech Innovation specialisation consists of a 60 EC track alongside the students' core MSc programme: Astronomy, Chemistry, Computer Science, Mathematics and Physics.

This thesis aims to demonstrate how the achromatic nature and design flexibility of liquid-crystal optics can be used to improve high-contrast imaging instruments to facilitate detailed exoplanet characterization.

The Astronomy and Instrumentation specialisation consists of 120 European Credit Transfer System (EC) points and includes highly specialized instrumentation courses, a selection of advanced electives and two research projects.

How safe do you feel walking on the street in Leiden? Do you feel safe, or are there situations that make you feel unsafe in the city? These are questions that city criminologist Marianne Franken of Leiden University wants to find answers to. In collaboration with the municipality of Leiden and the…

Our students and public and private organisations have much to offer each other. To connect students with organisations, FGGA facilitates this through an internship and traineeship platform: TRAIL.
