Combining weak and strong cluster lensing : Applications to simulations and MS 2137

Abstract

Aims. While weak lensing cannot resolve cluster cores and strong lensing is almost insensitive to density profiles outside the scale radius, combinations of both effects promise to constrain density profiles of galaxy clusters well, and thus to allow testing of the CDM expectation on dark-matter halo density profiles. Methods. We develop an algorithm… (More)
