GREAT3 results I: systematic errors in shear estimation and the impact of real galaxy morphology
Rachel Mandelbaum, Barnaby Rowe, Robert Armstrong +40
We present first results from the third GRavitational lEnsing Accuracy Testing (GREAT3) challenge, the third in a sequence of challenges for testing methods of inferring weak gravi…
The rise and fall of star-formation in merging galaxy clusters
Andra Stroe, David Sobral, William Dawson +6
CIZA J2242.8+5301 (`Sausage') and 1RXS J0603.3+4213 (`Toothbrush') are two low-redshift (), massive (), post-core passage merging clusters, whi…
MC^2: Galaxy Imaging and Redshift Analysis of the Merging Cluster CIZA J2242.8+5301
William A. Dawson, M. James Jee, Andra Stroe +7
X-ray and radio observations of CIZA J2242.8+5301 suggest that it is a major cluster merger. Despite being well studied in the X-ray, and radio, little has been presented on the cl…
Hubble Space Telescope/Advanced Camera for Surveys Confirmation of the Dark Substructure in A520
M. James Jee, Henk Hoekstra, Andisheh Mahdavi +1
We present the results from a weak gravitational lensing study of the merging cluster A520 based on the analysis of Hubble Space Telescope/Advanced Camera for Surveys (ACS) data. T…
