Gravitational Lensing Accuracy Testing 2010 (GREAT10) Challenge Handbook
Thomas Kitching, Sreekumar Balan, Gary Bernstein +32
GRavitational lEnsing Accuracy Testing 2010 (GREAT10) is a public image analysis challenge aimed at the development of algorithms to analyze astronomical images. Specifically, the…
Weak lensing from space: first cosmological constraints from three-point shear statistics
Elisabetta Semboloni, Tim Schrabback, Ludovic van Waerbeke +3
We use weak lensing data from the Hubble Space Telescope COSMOS survey to measure the second- and third-moments of the cosmic shear field, estimated from about 450,000 galaxies wit…
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…
Photometric redshifts: estimating their contamination and distribution using clustering information
Jonathan Benjamin, Ludovic Van Waerbeke, Brice Ménard +1
We present a new technique to estimate the level of contamination between photometric redshift bins. If the true angular cross-correlation between redshift bins can be safely assum…
