Henk Hoekstra Observational cosmologist

Henk Hoekstra’s research interests include observational cosmology, clusters of galaxies, galaxy formation, dark matter and dark energy. He has been actively involved in a number of large observational programs, including the CFHT Legacy Survey, that study dark matter and dark energy using weak gravitational lensing. For example, he has led observational programs to improve mass estimates of galaxy clusters.

Currently, he is using the KiloDegree Survey to learn more about the dark matter distribution around galaxies, groups of galaxies and to map the matter distribution as a function of cosmological distance. He is also leading the development of the weak lensing science case for Euclid, the ESA mission to study dark energy and many other aspects of our current cosmological paradigm.
