Henk Hoekstra

Research Summary

[ Cosmology and CMB, Planets and Planet Formation ]

Henk Hoekstra studies the distribution of dark matter in the universe through its weak gravitational lensing effect. The lensing signal induced by large scale structure can be used to constrain cosmological parameters, whereas the signal around galaxies provides a unique way to study their dark matter halos. Hoekstra uses data from various large surveys, such as the Red-Sequence Cluster Survey, VIRMOS-DESCART survey and the CFHT Legacy Survey. Recently, Hoekstra has started a project to search for binary stars in wide field imaging data.
