摘要 (Abstract): 

The Lambda-CDM model is a very successful description of the universe. It predicts how large-scale structures form and grow with time, leading to the present-day population of clustered galaxies.

In this talk I will describe how we are testing this model with gravitational lensing measurements of the large-scale distribution of matter, in particular from the Kilo-Degree Survey, a project to map 1300 square degrees of sky using the VLT Survey Telescope at ESO in Chile.

主讲人简介 (Speaker's CV): 

Positions held Full professor at the University of Leiden (2002-now) Faculty at the Kapteyn Institute in Groningen (1994-2002) Hubble Fellow at the Harvard-Smithsonian Center for Astrophysics (1991-1994) Postdoc at the Canadian Institute for Theoretical Astrophysics (1989-1991) Corporal in the Belgian Air Force (1989) Education PhD student at the Institute of Astronomy in Cambridge, UK (1985-1988) Research interests: dynamics of galaxies, gravitational lensing and dark matter. Science functions PI of the Kilo-Degree Survey (KiDS), mapping 1350 square degrees of extragalactic sky in multiple colours, with the aim to study the distribution of dark matter and the nature of dark energy, principally through the technique of gravitational lensing. Policy Functions From 2007 until 2012 I served as Scientific Director (dept. chair) of Leiden Observatory I am currently the chair of the NWO Science domain advisory committee for astronomy, and serve on the institute advisory board of ASTRON, and the Fachbeirat of the Max-Planck Inst. for Extraterrestrial Physics (MPE). Since 2007 I have been a member of the Dutch Committee for Astronomy (NCA), now known as the "Astronomy Council". Previously I served as member of the ESO Council and the SRON board. From 2008 to 2017 I was a board member of the Koninklijke Maatschappij voor Natuurkunde "Diligentia" in the Hague, which organises lectures for the broader public by professional scientists. Recent Awards In 2015 the Alexander van Humbold Foundation in Germany granted me a research award, with which to set up a collaboration with the excellent Argelander Institute for Astrophysics in Bonn. In 2016 I was elected a member of the Koninklijke Hollandsche Maatschappij der Wetenschappen in Haarlem.
