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

An international team of astronomers, including Leiden’s Christian Ginski, has discovered previously unobserved structures in a debris disk around a nearby star. Article published in Nature on 8 October.

Former PhD student Cameron Mackie will been awarded not one, but two dissertation prizes for his thesis on the aromatic universe. His work could provide us with a virtual sniff of space. ‘These molecules in space likely smell like a big charcoal grill!’

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…

A team of astronomers of Leiden University and the University of Texas (Austin, United States) has discovered a new way to map distant galaxies. They did so by observing the fingerprint of oxygen in a distant galaxy, something that is usually not possible from Earth. The researchers will publish their…

This research aims to fully recall these lost sound aspects of the eighteenth century and is, therefore, a study that passionately advocates the diversity of musical experience in the context of historical performance practice.

Why does the textural gap between the music that one can improvise and that which one can practice and learn to play (as in completely written-out music) seem to be bigger in the case of the guitar than, for example, in that of keyboard instruments?

The next generation of high-contrast imaging instruments on space-based observatories requires sophisticated wavefront sensing and control in addition to a high-performance coronagraph.

Harry’s research work looks at the techniques and influence of chordal and polyphonic accompaniment on viola da gamba in the sixteenth century.

NASA’s telescope SOFIA has provided a new glimpse of the chemistry in the inner region surrounding massive young stars where future planets could begin to form. Leiden PhD candidate Andrew Barr writes about it in the Astrophysical Journal. The scientists found massive quantities of water and organic…

What is the origin of solar systems?

How did galaxies form? How did galaxies evolve?

In order to analyze the challenges linked to data use in the context of nexus governance, Giest & Mukherjee use a policy design lens and more specifically the perspective of organizational policy instruments to look at the Mediterranean region.

From the effects of hormone fluctuations in women via the interior structure of giant planets to the prehistory of the languages: six Leiden researchers have been awarded a Consolidator Grant by the European Research Council.

Recent study led at the Leiden Observatory has observed Orion with unprecedented detail. New data from the Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes have been used to create this stunning image showing a web of filaments in the Orion Nebula. These features appear red-hot…

Professor Ewine van Dishoeck, together with an international team of colleagues, has written an overview of everything we know about water in interstellar clouds thanks to the Herschel space observatory. The article, published in the journal Astronomy & Astrophysics, summarizes existing knowledge and…

In addition to the walk-in tours at the visitor center, we also offer private tours for groups. These tours delve deeper into the history of the building, but also offer the opportunity to learn more about astronomy in general.

The Old Observatory has a rich history. On this page you will find a short version of the history that took place in the observatory.

On 18 December 2019, Marianne Lochs defended her thesis 'Contempt of court'. The doctoral research was supervised by Prof. C.P.M. Cleiren and Prof. J.H. Crijns.

In the past 30 years, over 5,000 planets have been discovered outside our solar system. One common exoplanet is the lava world, a hot super-Earth with oceans of liquid lava. Mantas Zilinskas developed models to simulate possible atmospheres of these. Those simulations provide guidance for astronomers…

Sasse, van Breen, Spears & Gordijn demonstrated an anger gap in response to sexism which was larger for women than for men and found evidence that expressed anger was associated with instrumental concerns.

His instrument, his technique, his music and his life

Sarah Giest, Assistant Professor at Leiden University, and Ishani Mukherjee researched the topic of 'Behavioural Insights Teams (BITs) and Policy Change: An Exploration of Impact, Location, and Temporality of Policy Advice'.

The management teams lead the department and consist of a General Manager, an Outreach Manager, an Instrumentation Manager, an ICT/Housing Manager, a HR/Finances Manager and an Education Manager.

What type of violones were used to perform Bach’s music in his time? And which octaves and tunings are appropriate for his stringed bass instruments?

An international team led by Leiden astronomers has discovered diverse ices in the darkest, coldest regions of a molecular cloud. To do so, they used the James Webb Space Telescope. This discovery allows astronomers to examine the simple icy molecules that will be incorporated into future exoplanets,…

Recent welfare reforms in the Netherlands show a trend of reducing welfare accessibility and increasing obligations. Although the effects thereof on directly-targeted economic outcomes, such as welfare dependency and labor participation, are often assessed, potential spillovers to other economic and…

The application procedure is broken down into three parts.

ILS organizes monthly Lunch Seminars in which all researchers from Leiden Law School can present their research. The idea is to share in an open and accessible way what researchers from other research programs and institutes are working on. During a seminar, two or three speakers will present their…

Astronomers led by Leiden astronomer Sebastiaan Haffert have directly imaged two planets that are gravitationally carving out a wide gap within a planet-forming disk surrounding a young star. While over a dozen exoplanets have been directly imaged, this is only the second multi-planet system to be p…

A signal that is present both in the centre of our Milky Way and in distant places in the universe could reveal the origin of dark matter. This is what Leiden physicist Alexey Boyarsky concludes in an article in Physical Review Letters.

An international team of astronomers, with researchers at Leiden Observatory playing a leading role, has mapped the fuel for galaxy formation in the iconic Hubble Ultra Deep Field. The results of the research have been accepted for publication in The Astrophysical Journal.

Dark matter represents around eighty per cent of the total mass in the Universe. Yet, we still don't really know what it's made of. Astronomer Pavel Mancera Piña is looking for answers. With a Veni grant from NWO and the most advanced telescopes, such as the James Webb Space Telescope, he will investigate…

A Dutch-Italian-German team of astronomers has observed a huge glow of radio emission around a cluster of thousands of galaxies. They combined data from thousands of LOFAR antennas that were focused for 18 nights on an area the size of four full moons. This is the first time astronomers have been able…
