For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disc surrounding a young star. The discovery reaffirms that the conditions that spawned the Earth and Sun are not unique in the Universe. The results are published…

Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers at Leiden Observatory in the Netherlands have for the first time detected dimethyl ether in a planet-forming disc. With nine atoms, this is the largest molecule identified in such a disc to date. It is also a precursor…

In the discs of dust and gasses around young stars, mysterious structures occur. Together with professor Ewine van Dishoeck, PhD student Paolo Cazzoletti investigate how we can explain these forms, such as rings, spirals and holes. On 12 December, he will defend his thesis.

Rychard Bouwens from the Leiden Observatory is the first scientist in the Netherlands to be assigned a Large Programme on the state-of-the-art ALMA telescope in Chile. With his team, he wants to use the unique capabilities of the billion-euro facility to investigate the build-up of massive galaxies…

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.

Leiden Observatory has achieved a rare feat: two of its research teams have been awarded prestigious ALMA Large Programmes, allowing them to study how galaxies formed and evolved in the early Universe using cutting-edge telescope observations.

Many protoplanetary discs in which new planets are formed are much smaller than thought. Using the Atacama Large Millimeter/submillimeter Array (ALMA) scientists of the Leiden Observatory looked at 73 protoplanetary discs in the Lupus region.

A team led by Leiden University in the Netherlands and the National Radio Astronomy Observatory have, for the first time, robustly detected semi-heavy water ice around a young sunlike star. In this ice, some of the ordinary hydrogen atoms have been replaced by deuterium, a heavier variant of hydroge…

Five projects with researchers from Leiden University have received a grant from the Dutch Research Council (NWO) to build or upgrade existing research facilities.

Lecture

Galaxy intrinsic alignments induce a major astrophysical contamination to weak gravitational lensing measurements and need to be modelled and mitigated when extracting cosmological information from such measurements.

Large pairs of planets thought to orbit each other without a star, do not exist after all. That conclude Leiden researchers, after extensive computer modelling and simulations. What the double dots seen by the James Webb Space Telescope are, remains a mystery.

Res Publica is a Dutch language journal for political science, public administration, European and international politics, political sociology, and communication science.

SuperCode: Sustainability PER AI-driven CO-DEsign

The brightness peak of the ring around M87's supermassive black hole has shifted 30 degrees counterclockwise in a year. This is shown by new images released by the Event Horizon Telescope consortium.

Public sector decision-makers operate amidst an abundance of information and unclear political objectives. Attention is the sine qua non of policy-making: What is attended to can be addressed in policy responses; what is overlooked or goes unnoticed cannot. Despite its importance, public administration…

A difficulty of studies on chemical kinetics are the reaction time scales and detection of their intermediates.

The central research question in this study was twofold: 1. To what extent are the three reconstruction models useful in a reconstruction of the public decision-making process concerning decentralized government between 1947 and 2014? 2. To what extent does the reconstruction of this public decision-making…
