What Lies Beneath: Using p(z) to Reduce Systematic Photometric Redshift Errors
D. Wittman
We use simulations to demonstrate that photometric redshift "errors" can be greatly reduced by using the photometric redshift probability distribution p(z) rather than a one-point…
Shear-Selected Clusters From the Deep Lens Survey III: Masses from Weak Lensing
Alexandra Abate, D. Wittman, V. E. Margoniner +4
We present weak lensing mass estimates of seven shear-selected galaxy cluster candidates from the Deep Lens Survey. The clusters were previously identified as mass peaks in converg…
Dark Matter Structures in the Universe: Prospects for Optical Astronomy in the Next Decade
P. J. Marshall, M. Auger, J. G. Bartlett +13
The Cold Dark Matter theory of gravitationally-driven hierarchical structure formation has earned its status as a paradigm by explaining the distribution of matter over large spans…
Exploring Dark Energy with Next-Generation Photometric Redshift Surveys
Hu Zhan, Andreas Albrecht, Asantha Cooray +15
The coming decade will be an exciting period for dark energy research, during which astronomers will address the question of what drives the accelerated cosmic expansion as first r…
Handbook for the GREAT08 Challenge: An image analysis competition for cosmological lensing
Sarah Bridle, John Shawe-Taylor, Adam Amara +35
The GRavitational lEnsing Accuracy Testing 2008 (GREAT08) Challenge focuses on a problem that is of crucial importance for future observations in cosmology. The shapes of distant g…
