Challenges facing young astrophysicists
N. L. Zakamska, A. E. Schulz, K. Heng +9
In order to attract and retain excellent researchers and diverse individuals in astrophysics, we recommend action be taken in several key areas impacting young scientists: (1) Main…
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…
Halo masses for optically-selected and for radio-loud AGN from clustering and galaxy-galaxy lensing
Rachel Mandelbaum, Cheng Li, Guinevere Kauffmann +1
We compute two-point correlation functions and measure the shear signal due to galaxy-galaxy lensing for 80,000 optically identified and 5,700 radio-loud AGN from Data Release 4 (D…
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…
Precision photometric redshift calibration for galaxy-galaxy weak lensing
R. Mandelbaum, U. Seljak, C. M. Hirata +26
Accurate photometric redshifts are among the key requirements for precision weak lensing measurements. Both the large size of the Sloan Digital Sky Survey (SDSS) and the existence…
