Catherine Heymans




Catherine is a Reader in Astrophysics at the University of Edinburgh, based at the Institute for Astronomy.

She has the pleasure of working with the KiDS, CFHTLenS and RCSLenS surveys, three of the largest deep ground-based surveys in existence, along with the Hubble Space Telescope GEMS and STAGES surveys. All of these surveys are ideal for her main area of research into the Dark Universe using weak gravitational lensing .

The Shear TEsting Program STEP lead to the GREAT challenges for which she has made public KSBf90, which is her software version of the typically used Kaiser, Squires and Broadhurst shape measurement method.

Modern astronomy has made some astonishing discoveries - how stars burn and how black holes form; galaxies from the edge of the universe and killer rocks right next door; where the elements come from and how the expanding universe is accelerating. But how do we know all that? The truth is that astronomy would be impossible without technology, and every advance in astronomy is really an advance in technology. But the technology by itself is not enough. We have to apply it critically with a knowledge of physics to unlock the secrets of the Universe.
