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…
CFHTLenS: Co-evolution of galaxies and their dark matter haloes
Michael J. Hudson, Bryan R. Gillis, Jean Coupon +16
Galaxy-galaxy weak lensing is a direct probe of the mean matter distribution around galaxies. The depth and sky coverage of the CFHT Legacy Survey yield statistically significant g…
Cluster Magnification & the Mass-Richness Relation in CFHTLenS
Jes Ford, Hendrik Hildebrandt, Ludovic Van Waerbeke +4
Gravitational lensing magnification is measured with a significance of 9.7 sigma on a large sample of galaxy clusters in the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS…
CFHTLenS: The relation between galaxy dark matter haloes and baryons from weak gravitational lensing
Malin Velander, Edo van Uitert, Henk Hoekstra +16
We present a study of the relation between dark matter halo mass and the baryonic content of host galaxies, quantified via luminosity and stellar mass. Our investigation uses 154 d…
