First Galaxy-Galaxy Lensing Measurement of Satellite Halo Mass in the CFHT Stripe-82 Survey
Ran Li, Huanyuan Shan, HouJun Mo +7
We select satellite galaxies from the galaxy group catalog constructed with the SDSS spectroscopic galaxies and measure the tangential shear around these galaxies with source catal…
First Measurement of the Cross-Correlation of CMB Lensing and Galaxy Lensing
Nick Hand, Alexie Leauthaud, Sudeep Das +33
We measure the cross-correlation of cosmic microwave background lensing convergence maps derived from Atacama Cosmology Telescope data with galaxy lensing convergence maps as measu…
Weak lensing mass map and peak statistics in Canada-France-Hawaii Telescope Stripe 82 survey
HuanYuan Shan, Jean-Paul Kneib, Johan Comparat +10
We present a weak lensing mass map covering ~124 square degrees of the Canada-France-Hawaii Telescope Stripe 82 Survey (CS82). We study the statistics of rare peaks in the map, inc…
Stochastic bias of colour-selected BAO tracers by joint clustering-weak lensing analysis
Johan Comparat, Eric Jullo, Jean-Paul Kneib +15
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 h…
