Probing Gravity at Cosmic Scales
The theoretical explanation of cosmic acceleration is nowadays one of the biggest puzzles in cosmology.

Shedding light on the dark side of the universe
It must be there. We just cannot see it: mysterious dark matter and dark energy in the universe. Henk Hoekstra is one of the many cosmologists who would love to know what exactly these substances consist of. He has received a European research grant of 1.3 euro million to find out.

ERC Advanced Grant for dark matter research
Dark matter. Something invisible that, according to calculations, comprises about 85% of the matter in the universe. With an ERC Advanced Grant of €2.5 million, Professor of Observational Cosmology Henk Hoekstra will map out even more precisely where this dark matter is to be found.

Exploring the Edge
At the largest scales, two ingredients dictate the distribution of matter in the Universe. The first is dark matter, acting as an invisible scaffolding held together by gravitational forces.

Gravitational waves through the cosmic web
The first direct detection of gravitational waves opened the possibility of mapping the Universe via this new and independent messenger.

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…

This is how ESA telescope Euclid is going to visualise dark matter
How can you see something that’s invisible? Well, with Euclid! This future ESA telescope will map the structure of the Universe and teach us more about invisible dark matter and dark energy. Scientific coordinator of Euclid and Leiden astronomer Henk Hoekstra explains how this works.
