Fast estimation of aperture-mass statistics I: aperture mass variance and an application to the CFHTLenS data
Lucas Porth, Robert E. Smith, Patrick Simon +2
We explore an alternative method to the usual shear correlation function approach for the estimation of aperture mass statistics in weak lensing survey data. Our approach builds on…
KiDS+VIKING+GAMA: Testing semi-analytic models of galaxy evolution with galaxy-galaxy-galaxy lensing
Laila Linke, Patrick Simon, Peter Schneider +9
Several semi-analytic models (SAMs) try to explain how galaxies form, evolve and interact inside the dark matter large-scale structure. These SAMs can be tested by comparing their…
Measuring galaxy-galaxy-galaxy-lensing with higher precision and accuracy
Laila Linke, Patrick Simon, Peter Schneider +1
Galaxy-galaxy-galaxy lensing (G3L) is a powerful tool for constraining the three-point correlation between the galaxy and matter distribution and thereby models of galaxy evolution…
CFHTLenS: A Gaussian likelihood is a sufficient approximation for a cosmological analysis of third-order cosmic shear statistics
P. Simon, E. Semboloni, L. van Waerbeke +10
We study the correlations of the shear signal between triplets of sources in the Canada-France-Hawaii Lensing Survey (CFHTLenS) to probe cosmological parameters via the matter bisp…
GaBoDS: The Garching-Bonn Deep Survey; IV. Methods for the Image reduction of multi-chip Cameras
T. Erben, M. Schirmer, J. P. Dietrich +21
We present our image processing system for the reduction of optical imaging data from multi-chip cameras. In the framework of the Garching Bonn Deep Survey (GaBoDS; Schirmer et al.…
