New KiDS result: Universe 10 per cent more homogeneous than assumed
New results from the Kilo-Degree Survey (KiDS) show that the Universe is almost 10 percent more homogeneous than previously thought. The new KiDS map was created using the partly Dutch OmegaCAM on ESO's VLT Survey Telescope on Cerro Paranal in Northern Chile. An international team of astronomers from,…

Irene Groot receives Vidi grant: looking at catalysts at atomic scale
Catalysts are indispensable in everyday life. We know what they do and more or less how they do it, but we still lack a fundamental understanding about their functioning at an atomic scale. Therefore, Irene Groot from the Leiden Institute of Chemistry develops new measuring techniques to unravel the…
