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…
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…
Cluster-lensing: A Python Package for Galaxy Clusters & Miscentering
Jes Ford, Jake VanderPlas
We describe a new open source package for calculating properties of galaxy clusters, including NFW halo profiles with and without the effects of cluster miscentering. This pure-Pyt…
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…
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…
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…
