How the speed demons of the universe tell us something about the Milky Way
They hurtle along at over a thousand kilometres per second: the fastest stars in the Milky Way. PhD candidate Fraser Evans conducted research into these elusive hypervelocity stars and discovered that they have a lot to teach us, about black holes and supernovae, for example.

First scientific images Euclid telescope exceed all expectations
Space telescope Euclid is capable of unravelling the secrets of the universe. That is what the images published by ESA today show, according to astronomers working with the telescope's data. The images exceed all expectations. Scientists within the Euclid consortium, including astronomers Henk Hoekstra…

Next quantum computer comes to the Netherlands
Europe's latest quantum computer is set to arrive in the Netherlands. The Dutch IT cooperative, SURF, which supports education and research institutions, has secured funding from the European EuroHPC programme to make this possible. Researchers from Leiden University will play a key role in the project,…

Two ERC Consolidator Grants for Leiden researchers
Research on quantum computers and Islamic charities: two Leiden researchers have received a Consolidator Grant from the European Research Council.

Special telescope measures neutrino with highest energy ever
Even with state-of-the-art technology, it is almost impossible to see: a cosmic neutrino. Yet scientists have managed to image this particle with a deep-sea telescope. And that could help to better understand our universe. Leiden particle physicists collaborated on this ambitious project, published…

The quantum computer: it doesn't exist yet, but still we understand increasingly better what problems it can solve
How do we know what a quantum computer is good for when it hasn't been built yet? That's what PhD candidate Casper Gyurik investigated by combining two terms you often hear: quantum computing and machine learning.

FLAMINGO: dark matter, ordinary matter, and neutrinos in the biggest cosmological simulation ever
Not only dark matter, but also ordinary matter and dark energy are tracked in the largest ever cosmological computer simulation ever. In the FLAMINGO simulations, you can see virtual galaxies and clusters of galaxies emerging over the course of billions of years. This is no easy task: with more than…

Looking for atmospheres in the ultimate quest for extraterrestrial life
To look for atmospheres around planets outside our solar system is to look for extraterrestrial life. Astronomist Sebastian Zieba used data from the James Webb Space Telescope to study small rocky exoplanets but found no aliens yet. However, his findings are still very interesting for future observations.…

Space telescope Euclid makes first test images - astronomers are full of anticipation
The two instruments of ESA's space telescope Euclid have taken their first test images. The first images indicate that the space telescope will achieve the scientific goals for which it was designed - and possibly much more. Euclid will create a 3D map of a third of the sky, allowing scientists to study…

Real-life data ask for strong algorithms: Mitra Baratchi designs them
How do we deal with large sources of greenhouse gases? Do schools provide a socially-inclusive environment for all children? And how can we protect Earth’s nature? These questions have two things in common: they are complex global challenges, and data can help answer them. Mitra Baratchi is computer…

Algorithms descend into our sewers to improve inspections
They never cross our minds until, that is, they become damaged and then they’re a huge problem: our sewers. Their maintenance could be much faster and more accurate, PhD candidate Dirk Meijer has discovered. Algorithms are also proving to be a godsend deep underground.

Using AI to track greenhouse gas emissions
PhD candidate Julia Wąsala searches for greenhouse gas emissions in satellite data. As a computer scientist, she bridges the gap between computer science and space research. ‘We really can't do this research without collaboration.’

Motion of stars near Milky Way's central black hole is only predictable for few hundred years
The orbits of 27 stars orbiting closely around the black hole at the center of our Milky Way are very chaotic. As a result, researchers cannot predict with confidence where they will be in about 462 years. ‘That is astonishingly short,’ says astronomer Simon Portegies Zwart who collaborated on the r…
