THOR: An Algorithm for Cadence-Independent Asteroid Discovery
Joachim Moeyens, Mario Juric, Jes Ford +7
We present "Tracklet-less Heliocentric Orbit Recovery" (THOR), an algorithm for linking of observations of Solar System objects across multiple epochs that does not require intra-n…
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…
Magnification by Galaxy Group Dark Matter Halos
Jes Ford, Hendrik Hildebrandt, Ludovic Van Waerbeke +6
We report on the detection of gravitational lensing magnification by a population of galaxy groups, at a significance level of 4.9 sigma. Using X-ray selected groups in the COSMOS…
CFHTLenS: A Weak Lensing Shear Analysis of the 3D-Matched-Filter Galaxy Clusters
Jes Ford, Ludovic Van Waerbeke, Martha Milkeraitis +17
We present the cluster mass-richness scaling relation calibrated by a weak lensing analysis of >18000 galaxy cluster candidates in the Canada-France-Hawaii Telescope Lensing Survey…
Magnification as a Probe of Dark Matter Halos at high redshift
Ludovic Van Waerbeke, Hendrik Hildebrandt, Jes Ford +1
We propose a new approach for measuring the mass profile and shape of groups and clusters of galaxies, which uses lensing magnification of distant background galaxies. The main adv…
Next Generation Virgo Cluster Survey. XXI. The weak lensing masses of the CFHTLS and NGVS RedGOLD galaxy clusters and calibration of the optical richness
Carolina Parroni, Simona Mei, Thomas Erben +14
We measured stacked weak lensing cluster masses for a sample of 1325 galaxy clusters detected by the RedGOLD algorithm in the Canada-France-Hawaii Telescope Legacy Survey W1 and th…
