Weak-lensing mass calibration of the Atacama Cosmology Telescope equatorial Sunyaev-Zeldovich cluster sample with the Canada-France-Hawaii telescope stripe 82 survey
Jean-Paul Richard Kneib, Huanyuan Shan
Mass calibration uncertainty is the largest systematic effect for using clusters of galaxies to constrain cosmological parameters. We present weak lensing mass measurements from the Canada-France-Hawaii Telescope Stripe 82 Survey for galaxy clusters select ...
Iop Publishing Ltd2016MultiDarkLens Simulations: weak lensing light-cones and data base presentation
Jean-Paul Richard Kneib, Johan Comparat, Huanyuan Shan
In this paper we present a large data base of weak lensing light cones constructed using different snapshots from the Big MultiDark simulation (BigMDPL). The ray-tracing through different multiple plane has been performed with the GLAMER code accounting bo ...
Oxford Univ Press2016Measuring subhalo mass in redMaPPer clusters with CFHT Stripe 82 Survey
Jean-Paul Richard Kneib, Huanyuan Shan
We use the shear catalogue from the CFHT Stripe-82 Survey to measure the subhalo masses of satellite galaxies in redMaPPer clusters. Assuming a Chabrier initial mass function and a truncated NFW model for the subhalo mass distribution, we find that the sub ...
Oxford Univ Press2016Cosmological constraints from weak lensing peak statistics with Canada-France-Hawaii Telescope Stripe 82 Survey
Jean-Paul Richard Kneib, Huanyuan Shan, Qiao Wang
We derived constraints on cosmological parameters using weak lensing peak statistics measured on the similar to aEuro parts per thousand 130 deg(2) of the Canada-France-Hawaii Telescope Stripe 82 Survey. This analysis demonstrates the feasibility of using ...
Oxford University Press2015First measurement of the cross-correlation of CMB lensing and galaxy lensing
Jean-Paul Richard Kneib, Huanyuan Shan
We measure the cross-correlation of cosmic microwave background (CMB) lensing convergence maps derived from Atacama Cosmology Telescope data with galaxy lensing convergence maps as measured by the Canada-France-Hawaii Telescope Stripe 82 Survey. The CMB-ga ...
Amer Physical Soc2015GREAT3 results - I. Systematic errors in shear estimation and the impact of real galaxy morphology
Frédéric Courbin, Jean-Luc Starck, Thibault Adrien Kuntzer, Malte Tewes, Huanyuan Shan, Marc Gentile, Guldariya Nurbaeva, Jun Zhang
We present first results from the third GRavitational lEnsing Accuracy Testing (GREAT3) challenge, the third in a sequence of challenges for testing methods of inferring weak gravitational lensing shear distortions from simulated galaxy images. GREAT3 was ...
Oxford University Press2015MASS-CONCENTRATION RELATION OF CLUSTERS OF GALAXIES FROM CFHTLenS
Jean-Paul Richard Kneib, Huanyuan Shan
Based on weak lensing data from the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS), in this paper we study the mass-concentration (M-c) relation for similar to 200 redMaPPer clusters in the fields. We extract the M-c relation by measuring the den ...
Iop Publishing Ltd2015First galaxy-galaxy lensing measurement of satellite halo mass in the CFHT Stripe-82 Survey
Jean-Paul Richard Kneib, Huanyuan Shan
We select satellite galaxies from the galaxy group catalogue constructed with the Sloan Digital Sky Survey spectroscopic galaxies and measure the tangential shear around these galaxies with the source catalogue extracted from the Canada-France-Hawaii Teles ...
Wiley-Blackwell2014Weak lensing mass map and peak statistics in Canada-France-Hawaii Telescope Stripe 82 survey
Jean-Paul Richard Kneib, Frédéric Courbin, Georges Meylan, Johan Comparat, Huanyuan Shan
We present a weak lensing mass map covering similar to 124 deg(2) of the Canada-France-Hawaii Telescope Stripe 82 Survey (CS82). We study the statistics of rare peaks in the map, including peak abundance, the peak-peak correlation functions and the tangent ...
Wiley-Blackwell2014Stochastic bias of colour-selected BAO tracers by joint clustering-weak lensing analysis
Jean-Paul Richard Kneib, Johan Comparat, Huanyuan Shan, David Schlegel
The baryon acoustic oscillation (BAO) feature in the two-point correlation function of galaxies supplies a standard ruler to probe the expansion history of the Universe. We study here several galaxy selection schemes, aiming at building an emission-line ga ...
